Metropolitan recently fabricated a pre-piped heat transfer system to a local chemical company. The unit was then shipped complete and ready for integration in the customer’s system, which is located outside of the United States. The system is designed to heat 160 GPM of a 50% Propylene Glycol Solution from 155°F to 158°F using 15 psig steam at the heat exchanger inlet (125 psig steam at the pressure reducing valve inlet and inlet to the skid).  The condensate section of the heat transfer package included a steam pressure powered pump along with the pump receiver to ensure proper condensate drainage from the heat transfer.  All water and glycol piping was fabricated from schedule 40 steel piping. All steam and condensate piping was fabricated using schedule 80 steel piping, with the majority of the piping being welded in lieu of threading.

This air-gap/ break tank system, for supplying non-potable water, was recently shipped to a Wastewater Treatment Facility in Washington.

This air-gap/ break tank system, for supplying non-potable water, was recently shipped to a Wastewater Treatment Facility in Washington.

Cross connections between city water supply and water piping in certain types of public and private facilities constitute a potential public health risk. Owners of properties that pose an actual or potential risk of contamination are required to install some means of cross-connection control on the main water pipes that supply their buildings. A device is needed to prevent potentially contaminated water from flowing back into the city’s water supply. Typical approved devices include reduced pressure zone device (RPZ), double check valve (DCV, DCVA), or a physical air gap. The use of RPZs requires a significant amount of regular maintenance to insure the water source is protected.

While RPZs and DCVs have been approved for years, many governing agencies are making the transition to an air gap/ break tank system. The use of an approved air gap system requires an isolated storage tank and a separate booster pump system to re-pressurize the water supply to the facility and it provides a more positive means of separation and protection of the public water system in the event of contamination within the customer’s facility.

Metropolitan Industries recently provided an air-gap/ break tank system, for the supplying non-potable water, at a Wastewater Treatment Facility located in Washington.

After years of using a RPZ backflow prevention device, the plant decided to replace the device with a more reliable prevention system, to completely eliminate the risk of contamination. The air gap creates a barrier to backflow so there is a zero percent chance the water will become cross-contaminated.

“More and more communities are beginning to look past RPZs and towards the air-gap/ break tank system,” said Metropolitan Industries National Sales Manager, Mike Tierney, “Metropolitan is one of the companies at the forefront of this technology.”

For this application, Metropolitan designed a triplex, pressure booster system with air gap protection for the non-potable water supply and a 540 gallon tank with a system capacity rated for 290 gallons per minute.

Variable frequency drives are often used on the air-gap water pressure booster. The VFDs accurately control the speed of the pump motor to maintain a constant pressure in the facilities water piping. VFDs also minimize the electrical power used to re-pressurize the water, saving the owner money on their utility bills.

Sewage treatment plants, laboratories, boiler plants, warehouses, manufacturing and processing plants are just a few of the types of facilities that can make use of an air gap pressure booster system as a positive means of cross-connection control. The packaged air-gap/ break tank system is typically supplied complete with tanks, pumps, motors, piping, valves and controls all factory assembled and tested.

With the liability of protecting a city’s water supply, there is a real need for a reliable system that is a fail-safe solution to protect the water.

Metropolitan supplied the municipality with a prefabricated housed system, including all associated pumps, piping and controls.

At Metropolitan Industries, our reach extends far beyond the Midwest. Our national sales team can supply customized pumping solutions shipped fully assembled for ease of installation. Over the years, we have provided domestic water booster systems, complete sump and sewage lift station packages and many more of our cataloged products to customers not just nationwide, but around the globe as well.

Our ability to deliver solutions to pumping challenges to all is demonstrated by the work done in the city of Marianna, Fla. Working with an existing pump system over 25 years old and in need of more pumping capacity, the city turned to the team of Blankenship Contracting, Inc., Pump and Process Equipment Company and Metropolitan Industries to provide a custom solution.

“The customer required a custom pump system package that would not only provide more flow to account for increased demand, but could also supply the fire flow if needed,” said Pump and Process Equipment’s Eric McGee. “To meet these specifications, we designed a three-pump system housed in a prefabricated steel building, all of which was supplied by Metropolitan.”

Each of the three pumps is designed to provide a flow of 750 GPM at 134 feet of TDH. Each pump motor is rated at 40 HP and performs at 3500 RPM at 76.6 percent efficiency.

The prefabricated galvanized steel building includes a 72-inch by 84-inch double door entry to the pump room and a “pebblestone” exterior finish for an attractive design solution.

The system will primarily serve a nearby health department and surrounding residents.

McGee said initial design discussions planned to incorporate a two-pump system, but after discussing options with Metropolitan salesperson Mike Tierney, the group came to a resolution to implement a three-pump system housed in a prefabricated structure.

“We originally planned to build a system with two large pumps, but instead, designed a system with three smaller pumps for a variety of reasons, one of them being energy-efficient operation,” said McGee. “With three pumps, we can run just one at low loads. If the demand increases at any time, the other pump(s) will kick into gear.”

McGee said one of the primary challenges faced was meeting a short lead time, which forced the team of Metropolitan, Pump and Process and Blankenship to complete the project in a quick and well-organized fashion.

“From start to finish, we only had around 8 to 10 weeks to complete the project,” said McGee. “It required a team effort from everyone involved and thanks to a well-executed plan, we were able to deliver the system to our customer on time.”

In order to ensure water operators were familiar with the new system, Metropolitan sent service technicians to the job site to conduct training.

“Training provides a good start for customers when becoming acclimated to a new system,” said McGee. “Knowing the major do’s and don’ts of a system can make for a smooth transition.”

McGee said working with a single source provider was critical to Pump and Process and a chief reason why Metropolitan was involved with the project.

“We wanted to partner with an organization that had all capabilities under one roof,” said McGee. “Metropolitan was able to provide manufacturing, controls, pumps and service. We were comfortable having to contact one sole organization if any issues arose.”

Since installation, McGee said the system has run “flawlessly” and described his overall experience of working with Metropolitan as positive.

“When working with Metropolitan, the word professionalism comes to mind,” said McGee. “We’ve worked with many businesses in the water and wastewater industries and appreciate the way Metropolitan communicates with its customers. The ‘no excuses’ approach they take to developing a system ensures quality is of supreme concern.”
