Condensate Return Pumps

The float, which is connected to the switch assembly, rises when condensate enters the receiver tank. When the float rises above its set point, it energizes the motor on the pump. Once started, the pump will continue to run until the water level drops below the bottom position of the float switch.There it will de-energize the motor to shut off the pump. This cycle repeats as condensate begins to fill the receiver tank. On duplex systems the float switch is replaced with a Mechanical Alternator-Switch connected to a float. The Mechanical Alternator cycles use between the two pumps, allowing only one pump to run at a time under normalconditions. If the condensate reaches a high water level, both pumps will be activated.

How Condensate Return Pumps Work

Condensate Return Pumps are designed to operate intermittently, discharging condensate only when the receiver tank is full. This is accomplished with a float switch that energizes the pump when the float rises above a set point. Once started, the pump will continue to operate until the water level drops below the bottom set position of the float switch. On Duplex condensate return pumps, a Mechanical Alternator float switch is mounted to the receiver so that both pumps are used in an alternating manner.

The Condensate Return Pumps (W4100 series) are equipped with Cast Iron bodies and Bronze Impellers. The pump receiver tank is made of Carbon Steel and available in Simplex or Duplex configurations.
