Condensate Pumps

Condensate Pumps

Condensate Pumps for removal of condensate from high efficiency furnaces, A/C equipment, ice machines, drinking fountains, beverage machines, dehumidifiers and other applications requiring condensate removal. Condensate is produced at a rate of up to a gallon per hour by a residential central air conditioning unit or gas condensing furnace. The condensate is gravity fed from the appliance drain into one of the inlet ports of the condensate pump. A tubing is connected from the condensate pump check valve to a drain line, sump, french drain or laundry sink. The "Head" of the condensate pump refers to the height the pump is required to "lift" the water. The "run" is the distance the water travels horizontally once the lift is reached. The "run" does not affect the pumps lift or flow rate unless it exceeds 50 feet. "Runs" of 50' or more will decrease pump output by about 10%. All pumps should have the auxiliary safety switch wired in-line to shut down the appliance or wired directly to an alarm, in the event of a pump overflow. Pump overflow can be caused by a blocked discharge line, power loss to the pump, or pump malfunction.
