- Industry / Applications
Carotek has significant expertise in the application of pumps for the movement of condensate.
Condensate pumping brings a great deal of challenges that require both the proper selection of type pump to be used and the correct installation of the pump. Armstrong International offers both electric condensate pump packages and mechanical steam or air powered pump packages (pressure powered pumps).

Electric Condensate Pump
The electric condensate pump package has advantages such as:
Small package sizeExcellent for returning cooler condensateInexpensive initial purchase priceLow inlet height requirementsCan operate against high back pressure
Unfortunately, they also have several disadvantages including high maintenance cost on hot condensate applications due to NPSH issues, electrical safety in wet areas and units must have a 3:1 safety factor on receiver for condensate cooling.
Pressure Powered Pump
They have advantages over electric condensate pumps including:
No seals, motors or impellers thus lower maintenanceElectric Condensate PumpsSized for actual condensate loadNo need for a 3:1 safety factorCan be used in closed loop applicationsSingle trade to install and repairCan return hotter condensate in closed-loop systems increasing efficiency and reducing Carbonic acid potentialOften the superior choice for long term reliability.
