Do I need a high temperature seal for my condensate pump? »

Volume 3/ Issue 2/ May 2016 Rapid or repeating pump failures often lead clients to ask if a high temperature seal is needed. But it’s more likely there are NPSH problems. Keep in mind that the maximum temperature that can be reached in the receiver is 212ºF. Domestic Pump condensate and boiler feed receivers are

Pressure testing Series 2000 valves »

Volume 3/ Issue 2/ May 2016 A customer recently asked our recommendation on testing the regulator valve and piping between the PRV station shutoff valves. “I am required to hydro test to 150 PSI on the high pressure and 60 PSI on the low pressure steam,” he wrote. “Could these test pressures damage the regulator

Sizing boiler feed units vs. condensate return units »

Volume 3/ Issue 1/ March 2016 We’ve previously discussed how to size condensate return units. Sizing a boiler feed unit requires similar information but is affected by differences in design and operation. Condensate return units are generally smaller, fitting their function of collecting steam condensate and pumping it back into the system before too much

Two pressure-reducing valves (PRVs) in series (Two-step pressure reduction) »

Volume 3/ Issue 1/ March 2016 Application Reduce a steady or varying high inlet pressure to a constant adjustable low delivery pressure. General Two pressure-reducing valves in series are generally used when the total reduction in pressure is greater than that attainable with one valve. Here’s the rule of thumb: Use a two-step reduction whenever

How to run a condensate zone off a steam boiler »

Volume 2/ Issue 5/ September 2015 1. Can I run a hot water zone off an existing steam boiler without a heat exchanger? Yes, but there is a limit to how much radiation your steam boiler can support. Manufacturers list two capacity outputs on every steam boiler: the Department of Energy (DOE) capacity, aka the

Adding chemical treatment to boilers »

Volume 2/ Issue 5/ September 2015 An engineer planning to specify a Domestic 75CBM22-85 BFU recently asked us if it’s feasible to have a chemical feed pump come on at the same time as the make-up to the BFU. The chemicals wouldn’t be pumped into the receiver, but instead added to the make-up water. We
