  • Packaged Pumping Units

  • Condensate Pumping UnitsCondensate Return Pumping Units are packaged assemblies consisting of a receiver (either Cast Iron or Steel), Pump and Motor (either Simplex or Duplex) and control device to turn the pump motor on or off.  They are designed to collect condensed liquid at remote locations in a steam system and move it back to the boiler room. The Units can be powered by either electricity or steam. Electrically powered units are the norm while the steam-driven units are typically used in hazardous environments or where electricity may not be readily available.

    Many variables come into play when selecting a suitable Condensate Return Pumping Unit including:

    • System Capacity (generally a function of boiler horsepower) and determines tank size
    • System Type (Vacuum or Gravity)
    • Outlet Pressure requirement (which determines motor HP)
    • Electrical requirement (single or three phase, voltage)
    • Type of  motor (TEFC, Explosion-Proof, Open Drip)
    • NPSH (determines type of pump)
    • Tank material (determines service life of receiver)
    • Single or Double Pump Design
    • Accessories (e.g. Pressure Gauge, Water Level Gauge Glass, Isolation Valve, etc.)

    Boiler Feed Pumping Units

    Boiler Feed Pumping Units are packaged assemblies consisting of a receiver (either Cast Iron or Steel), Pump and Motor (either Simplex or Duplex) and control device to turn the pump motor on or off (usually controlled by the boiler). They are designed to send condensed liquid from the system, augmenting it with make-up water when required, to the boiler. They are generally larger than the Condensate Return Pumping Unit(s) found in the system as they must store boiler feed water until the boiler calls for additional water. Many of the same criteria as used to select a Condensate Return Pumping Unit are used to select a Boiler Feed Pumping Unit with the additional variables:

    • Type of make-up water control (float or solenoid)
    • Horizontal or vertical design

    Benefits:

    • Achieve substantial energy savings by collecting the already heated condensate and returning it to the boiler thereby lowering the consumption of fuel needed to heat the much cooler make-up water.
    • Lower operating costs by reusing condensate already chemically treated thereby reducing the consumption of additional chemicals needed to treat fresh make-up water.
