The popular Bell & Gossett System Syzer software program is now available as a mobile application for the Android operating system.

Widely recognized as the industry standard for calculating flow rates and pressure drops in piping systems, the System Syzer Android app can be downloaded for free from the Google Play Store^TM  HVAC professionals with a smartphone or smart mobile device can now enjoy the same functionality and program features while working in the field.

The System Syzer performs several critical calculations and offers a variety of unique features, including:

Calculating the friction loss and velocity through various pipe types and sizes based on existing fluid conditions.
Calculating the relationship between fluid temperatures, system flow and heating/cooling load.
A unique Cv tool that shows the relationship between Cv, flow and head and accounts for fluid properties.
A Pipe Length/Pressure Drop tool that interfaces with the other calculators to view the relationship between pipe length, friction loss and total head loss.
A bundled Circuit Setter®/Triple Duty Valve calculator that is very useful during the design phase to help predetermine valve settings, and out in the field, to determine flow through the valves based on pressure drop readings.
The System Syzer application is based on the novel plastic wheel calculator designed by Bell & Gossett’s Gil Carlson. Widely recognized as the ‘Father of Modern Hydronics,” Carlson first introduced the System Syzer in 1963; it has since been distributed to well over 100,000 engineers and tradesmen.

The System Syzer was released as an app for Apple iPhone® and iPad® devices last year. It is also available for free download on all iPad and iPhone devices from the iTunes App Store®.

The High Temp Sump Pump is designed for extreme operating conditions and is instrumental where liquids are too hot for conventionally built submersible pumps. This would include moving wastewater coming from high temperature processes like boiler blow down or hot water rinses in the commercial plumbing market and applications requiring handling liquids up to 200ºF.

Bringing Bell & Gossett systems expertise to heat transfer package building ensures that every installation is as efficient and effective as it can be at the job site.

This week Xylem participated in the much-anticipated Golf Industry Show and displayed their many solutions in booth 4628, February 6-7 at the San Diego Convention Center, where it’s always perfect golfing weather. The show combines education, networking and product solutions for golf course superintendents, equipment managers, owners/operators, general managers, chief operating officers, architects and builders.

Presented by the Golf Course Superintendents Association of America (GCSAA) and the National Golf Course Association of America) (NGCOA), thousands of exhibitors, distributors, buyers and media packed the San Diego Convention Center to get face time with industry experts, preview the latest products, and gain educational credits.

The Xylem team representing the Flowtronex and WET brands brought their green solutions to the show. The products included:

• Evacuator 8000 is the latest high efficiency potable utility pump designed specifically to help with the removal of water in sand traps and bunkers. Sand trap maintenance is one of the most time consuming jobs for busy groundskeepers. Heavy rains and inadequate drainage systems can cause standing water in the bunker, causing more of a hazard than desired. Standing water on sand traps should be removed as soon as possible to prevent contamination and bacteria growth, not to mention the complaints of the golfers. Providing a robust 2000 GPH, a capable 4000 GPH, or a sizeable 8000 GPH, the Evacuator series provides a perfect collaboration between size and functionality. The innovative power connection, which allows for direct operation from any vehicle’s 12 volt battery via two heavy duty battery clips, provides flexibility for use in work environments requiring fast, efficient removal of water.

• Silent Storm represents the apex of variable speed water pumping system technology. Designed for easy set and start, it is designed to meet specific requirements. The Silent Storm VFD systems are completely UL Listed for both US and Canada, and CE rated for Europe. Available in vertical and horizontal configurations, Silent Storm irrigation pump systems work in harmony with our line of integrated water management solutions to bring the source water to the course.

• Silent Storm Express is a golf course pump station that is available for delivery in only 4 weeks and represents the apex of variable speed water pumping system technology. Designed for easy set and start, Silent Storm integrates precision computer control with Variable Frequency Drive (VFD) efficiency, giving golf course superintendents the ultimate in fully programmable pump stations.

• RO System Golf course irrigation can present unique challenges. The Water Equipment Technologies reverse osmosis system provides up to 600,000 GPD of water for irrigation from brackish water wells. This unique system combines two 300,000 GPD systems on one skid. Each train can be operated independently of the other or at the same time.

At last year’s show Xylem donated a Flowtronex Silent Storm Express pump system that was displayed in the booth prior to shipping it to the American Lake Veterans Golf Course. The pump system was a crucial element in the renovation of the veterans-only golf course that helps in the healing process from all types of physical and mental wounds and relies on private donations and volunteers to run it. Earlier this month, the participating partners were featured in GCM magazine.

We hope to see everyone again next year in Orlando!

Yesterday was a very interesting day at the Little Red Schoolhouse. We had the privilege of hosting David Jern and Cliff Reis from the American Society of Plumbing Engineers (ASPE) at the Xylem facilities in Morton Grove, Illinois. Among the items on our agenda was discussing how we might collaborate on industry training and educational opportunities.

Many of you are probably familiar with ASPE, and some of you are probably members. But for those of you that are not familiar with the organization, it is the international society for professionals skilled in the design, specification and inspection of plumbing systems. They are dedicated to the advancement of the science of plumbing engineering, to the professional growth and advancement of its members and the health, welfare and safety of the public.

The meeting covered a variety or topics, but the main focus was how we might work more closely together to enhance industry educational opportunities. Since both of our organizations are dedicated to providing valuable training and educational programs to all levels of HVAC and plumbing professionals, we felt there had to be some opportunities worth exploring.

After all, ASPE provides plumbing engineers and designers with myriad of ways to enhance their skills and knowledge, while earning the continuing education units needed for certifications and professional registrations. Likewise, Bell & Gossett has led the industry in providing high-quality continuing education programs focusing on HVAC and plumbing for nearly 60 years.

In fact, we are very proud that we were just approved for LEED certification for another one of the LRSH’s industry-renowned courses. The Schoolhouse’s Design & Application of Water Based HVAC Systems course has been approved by the Green Building Certification Institute (GBCI) to provide credit toward the credential maintenance requirements of LEED certifications. This is the third course that the Little Red Schoolhouse offers, which provides credit toward the credential maintenance requirements of the LEED Green Associate and LEED AP certifications. The other courses are Large Chilled Water System Design and Modern Hydronic Heating Systems – Basic.

Did you know that since 1954, more than 55,000 engineers, contractors and installers have been trained in the Little Red Schoolhouse’s fully equipped learning center, while another 150,000-plus professionals have received training through Bell & Gossett’s ‘traveling classroom’ program. And, the graduates of the Little Red Schoolhouse can be found in every state in the U.S. as well as Europe, the Middle East, Asia, Latin America, and Australia.

We look forward to continuing these discussions to identify new educational solutions with ASPE. Working and teaming with associations such as APSE helps to create a stronger and more educated industry, which in the end helps our industry.

This year’s Miami International Boat Show was especially “sweet” for the Xylem brands being showcased there. Beginning on Valentine’s Day, February 14, the massive event attracted more than 100,000 attendees from around the world. At times, it seemed that most of them were packed into our booth to see the latest line-up of the Jabsco^® and Rule^® products.

For those of you who have never attended the event, it is considered the premier focal point for new product launches, which makes it a great networking event within the marine industry, and a way to gauge public reaction to our products. The 2013 show was no exception. It is produced by the National Marine Manufacturers Association (NMMA), the world’s largest producer of boat shows and the leading association representing the recreational boating industry.

Although one may think it is challenging to compete for attendees’ attention against multi-million dollar yachts, an incredible array of boats and big-name celebrities featured at the show, we were very busy meeting with our channel partners and the buying public.

Xylem featured products from its line of marine brands. Many of the products and accessories featured at the show were part of fully functional demos presented by the company’s team of marine experts. Among the products on display included:

• Jabsco Lite Flush™ electric toilet
• Jabsco Vflo water pressure pump
• Jabsco PAR-Max^TM Plus water pressure pumps
• Jabsco HotShot^TM washdown pumps

We wrote this week’s blog from ISH 2013 in Frankfurt, Germany, where more than 200,000 engineers, contractors, architects and other building services professionals from nearly 50 countries come together to see all the latest product innovations and technologies at what is billed as “the world’s biggest exhibition of water and energy”.

Taking place from March 12-16, ISH showcases everything from energy efficient heating technologies combined with renewable energies to environmentally friendly air-conditioning, cooling and ventilation technology. It truly covers all aspects of future-oriented building solutions in both horizontal and vertical terms.

Xylem and other global market leaders are among the more than 2,300 exhibitors displaying the latest energy efficient technologies and working with customers to find innovative solutions to their specific challenges. At the Xylem booth, we’re introducing our customers to several new products from our leading brand Lowara. The demos include two new additions from the family of Ecocirc^® high efficiency circulator pumps:

• The Lowara XL is a large wet circulator developed for commercial applications. This pump can meet heating and cooling requirements across a broad range of applications but still maintain the value and energy efficiency that customers have come to expect with the Ecocirc series.
• The Lowara Ecocirc domestic hot water pump is now offered with the option of a new air purge control function – an innovative function that rids domestic water systems of troublesome air pockets within the pump housing quickly and cost effectively.

Another new product we announced at the show is the Lowara e-HM, which is a stainless steel, horizontal, multi-stage pump specifically designed for residential applications.

Although many of the visitors to our booth thus far have had specific installation challenges, they were all seeking to save energy and more effectively manage water. We find it very interesting that although there are attendees from many countries, the world truly speaks the same language when it comes to energy efficiency, technology and water conservation.

If you attended ISH 2013 already or plan on attending in the next two days, we hope you stop by the Xylem booth to see our products first-hand. If you aren’t able to attend visit our virtual booth to see what you missed.

Morton Grove, Ill. April 2, 2013 — Xylem’s Paul Ruzicka, chief mechanical engineer and James Roberts, chief product engineer were recently honored by the Hydraulic Institute for their technical leadership and contributions in the creation of new ANSI/HI Standards for pumps.

The Hydraulic Institute (HI), under the approval of the American National Standards Institute (ANSI), recruits technically qualified individuals from North American companies that are directly and materially affected by the standard to participate in the review process.

ANSI/HI standards are reliable, widely accepted references for anyone involved in the pump industry. Those involved can include users, consultants, engineers, contractors, construction firms, pump manufacturers, and pump software developers and systems integrators. HI periodically introduces new standards based on industry needs.

Ruzicka, an active HI committee chair, has been an active member of the Institute for 21 years and was recognized for his work on two standards. The first was Rotodynamic Pumps Guideline for NPSH Margin, ANSI/HI 9.6.1-2012, which establishes margins over NPSH3 that will lead to acceptable pump performance and service life. The second was Rotodynamic (Centrifugal and Vertical) Pumps – Guideline for Allowable Operating Region, ANSI/HI 9.6.3-2012. This standard provides guidance for determining the Allowable Operating Region (AOR) and Preferred Operating Region (POR) for rotodynamic pumps as related to the Best Efficiency Point (BEP) of each pump.

“Seeing the efforts of all the members that work to drive the standards to completion and to publication is truly satisfying,” said Ruzicka. “I’m proud to be a member that is part of the core team and grateful for the opportunity made available to me by Xylem to be a HI member.”

James Roberts was also honored by the HI for his contributions to three standards committees. He has participated in more than a dozen HI committees in his 18 years of membership. Roberts was recognized for his contributions as a member of the committee that developed Rotodynamic Pumps for Pump Intake Design, ANSI/HI 9.8-2012. This new version represents a significant update with twice the content as the 1998 version.

Roberts also joined Ruzicka on the Rotodynamic Pumps Guideline for NPSH Margin, ANSI/HI 9.6.1-2012 and Rotodynamic (Centrifugal and Vertical) Pumps – Guideline for Allowable Operating Region, ANSI/HI 9.6.3-2012.

“Working with the other members of the HI committees is very rewarding. It’s been a great way to learn and grow from others experiences. Most of the members have many years of experience in the pump world,” Roberts noted.

Xylem recognizes the value of ANSI/HI Standards and encourages staff to participate on HI committees. Xylem has long been a member of HI, which is the largest association of pump producers and suppliers to the pump industry in North America and a global authority on pumps and pumping systems.

As you know, primary-secondary pumping is simple in theory as well as in operation. It is based on a simple fact: when two circuits are interconnected, flow in one will not cause flow in the other if the pressure drop in the piping common to both is eliminated.

Each type of pumping system configuration has distinct advantages for the user or operator.  Fundamental to all of these configurations is sound design principles. Without the proper application of the basics, the most sophisticated systems will not operate effectively.

To optimize system performance, the designer has a number of variations of basic primary-secondary pumping to explore. Standard rules of thumb are:

• THE COMMON PIPE: The key to all primary-secondary applications is the use of a common pipe, which interconnects the primary and secondary circuits. The length of this pipe should be kept very short in order to keep the pressure drop very low, and the supply and return tees to the secondary circuit should be a maximum of four pipe diameters apart. By keeping the pressure drop very low, water that is flowing in the primary loop will not flow into the secondary circuit until its circulator turns on.

• THE SECONDARY PUMP: A separate pumpis installed in the secondary circuit to establish flow. This pump is sized to move the flow rate and to overcome the pressure drop of its circuit only. The pump should be located so it is pumping away from the “common piping” and discharging into the secondary circuit. This causes an increase in pressure in the secondary circuit rather than a reduction in pressure, which would occur if the pump were located on the return pumping towards the common pipe.

• THE LAW OF THE TEE: This rule determines the flow rate and direction of flow that occurs in common piping. It is based on the relationship of the primary and secondary flow rates, and there are three possibilities to evaluate:
  • Primary flow more than secondary
  • Primary flow equal to secondary
  • Primary flow less than secondary

This rule of thumb is best described by a simple statement: flow into a tee must equal flow away from the tee.

Finally, there are two important advantages to primary-secondary pumping:

1. Less energy is required to move water through the entire system (rather than one large circulator, small energy efficient circulators can be used to overcome the friction and inertia (“pressure drop”) of their respective loops).
2. More control can be taken over zones (and each zone can operate at its own optimum temperature).

There are many ways modern HVAC systems can be pumped. Each method has its own advantages and disadvantages to the user or operator. The designer must consider present system use, plans for the future, cost considerations, and the ability level of the operator. With more tools in the toolbox, the engineer is better equipped to make the decision, “Which system is the best for my client?”

Are the days of wasted electrical energy through poorly designed hydronic systems with low efficiency circulators about to end? We say yes, with the help of electronically commutated motors (ECM).

Many industry experts consider ECM-based circulators one of the major advancements in hydronics technology over the last two decades and with good reason as the advanced technology provides much greater efficiency for heating and cooling systems. They are quickly becoming the “new normal” in hydronic system design.

The reason we bring this up is that next week with help and coordination from one of our media partners, we will be sponsoring a webinar entitled, “Smart Pumping – The “New Normal” in Hydronics”.

Moderated by industry guru John Siegenthaler, the webinar will explain the benefits these circulators offer, and show you how to best apply them in residential and light commercial hydronic systems. It will cover both basic and unique applications for the Bell & Gossett VARIO and AUTO circulators. Why not make the “hydraulic efficiency” of your systems on par with their thermal efficiency? This webinar will show you how to do just that.

What also makes this webinar valuable is that John provides great insight from the perspective of an engineer with over 25 years of experience in designing modern hydronic heating systems. He is also the author of the text Modern Hydronic Heating, and writes for several other industry publications dealing with hydronic heating, including Plumbing & Mechanical, PM Engineer and Heating Piping & Air Conditioning.

For many of us in the building services industry, webinars have become a great way to gain technical knowledge on specific topics without ever needing to leave the office. If you are not able to join us, you can still gain access to the archived webinar by registering here.

We hope you can make it Thursday, April 18, at 1 pm CST.

It’s been six months since Hurricane Sandy devastated the northeastern United States. The impact was significant, with a total of $71 billion in damages caused by the storm, as referenced by the New York Daily News. In addition to the economic tragedy left in the hurricane’s wake, the environment was also hit hard. According to a report released earlier this week by Climate Central, Hurricane Sandy flushed 11 billion gallons of sewage into New York and New Jersey’s waterways, destroying miles of beautiful shoreline. How much sewage is 11 billion gallons exactly? Enough to fill Central Park’s 843 acres and then piled 41 feet high. Water quality issues and damage to sewage facilities – totaling $2 billion in New York City alone – are two serious outcomes of the storm that are still being dealt with today.

But recovery efforts continue, even as the 2013 hurricane season looms on the horizon. The Federal Emergency Management Agency (FEMA) recently announced that it will give more than $5 million to reimburse repair and reconstruction costs for damaged New York City pump stations. Many stations were damaged when salt water submerged the sites, flooding underground concrete vaults and damaging electrical equipment.

Numerous organizations stepped up to help the storm-ravaged city repair infrastructure and pumping facilities that were overcome by the storm. Xylem’s dewatering solutions and Godwin brand pumps helped dry out transportation tunnels, train stations and basements in New York City and surrounding areas. Xylem also deployed more than 200 Evacuator pumps to move water out of residential and commercial buildings – even before power was restored.

Outreach after Hurricane Sandy went beyond companies simply sending the right products to expel flood waters, restore electricity and gas service, and rebuild structures. It was the hard work of employees who swiftly manufactured and shipped pumps to the affected areas. It was the flexibility of those who transported materials to the flood sites, as they rerouted other shipments and navigated debris and power failures across the region to get supplies to the east coast. It was the long hours in cold weather of the workers who operated the pumps, working tirelessly to reopen main arteries of the city. True support was shown when all these people and organizations pulled together to support the storm-stricken communities and their residents.

The damaged region has made a lot of progress in the past six months, but still has a long road ahead.

With summer just around the corner, recreational boat owners are preparing to launch their pontoons, speedboats and fishing boats for a season on the water. However, taking care of a watercraft can be more of an undertaking than one might anticipate.

There are many areas that require maintenance and inspection before a boat can be launched and driven safely. Among the most crucial equipment to check thoroughly are the pumps and the systems connected to them.

Keep the tips below in mind as you prepare your boat and its components for summer. The following measures will help prevent problems that could ruin your first outings of the boating season.

• Keep pumps clean and free from debris: It is vital that the bilge pump be checked often to ensure that the pump and inlets around it are clean. Ensuring there’s no debris near the pump is also important so that seaweed, driftwood or other items don’t get sucked up into the boat engine.

• Test the automatic float switch: Manually raise the float switch to ensure it properly triggers the bilge pump. If the switch fails to turn on the pump, your boat could take on too much water, resulting in serious damage.

• Inspect fluids: Take a close look at fuel, oils and other fluids, as well as their lines, which may have become damaged or contaminated while the boat was not in use.

• Check for leaks: Inspect your boat’s water system and pumps for oil, fluid and water leaks. Seals, impellers, hoses, hose clamps and gaskets should be checked for deterioration, which can cause harmful leaks and costly damage.

• Keep a strong battery: It is important to keep batteries in top condition. Clean, tight battery connections will help your boat’s pumps run smoothly all summer long. To avoid overloading the battery, unplug the stereo, cooler and other accessories on board before starting the boat engine.

• Ensure a functioning manual pump: If your boat’s battery dies and you get stranded, a properly operating manual bilge pump will keep too much water from amassing in the bilge and help you avoid sinking.

If you remember these tips, your boat and pumps should be ready to hit the water for the summer. Whether navigating lazy rivers, congested lakes or rough seas, it’s important to take the proper precautions when launching your boat. Where will your summer boating excursions take you?
