About Condensate Pumps
Condensate pumps are used to pump condensation from vapor in steam systems. In steam systems, a condensate pump receives the condensate from several condensate piping systems, and then pumps the condensate to a main condensate tank or a deaerator tank. Condensate pumps’ role in recycling condensate greatly increases the efficiency of producing steam by reducing consumption of water, boiler chemicals, and energy needed to heat water to steam.
Insulating Condensate Pumps
With the exception of some centrifugal pumped condensate receivers, most experts agree that condensate pumps that employ steam or air to move condensate should be insulated for maximum energy efficiency. Condensate pumps are just one part of a complex condensate system, and any weak link can compromise energy efficiency. Pumps, condensate lines, and condensate tanks should be insulated, so as to avoid losing any thermal energy in the condensate. These components in the condensate system typically exceed the maximum temperature threshold of 120 °F, above which energy is compromised, so reducing that temperature is important. Insulation on condensate pumps will also improve plant safety, as workers are better protected from the hot condensate system.
