During the fill cycle, fluid flows from the receiving chamber (A) through the inlet check valve (B) into the pumping chamber (C). The 3-way valve (D) is open between the pumping chamber and the receiving chamber, equalizing the pressure between them through the equalizing line (E).
Stage 2
When the level control (F) senses that the pumping chamber is full, the 3-way valve energizes to admit the motive pressure into the pumping chamber (C). The inlet check valve (B) prevents backflow into the fill line.
The discharge cycle begins when pressure inside the pumping chamber is greater than in the discharge line. The discharge check valve (G) opens and fluid flows into the discharge line. During this cycle, incoming condensate is stored in the receiver.
Stage 3
Once the level control (F) senses the pumping chamber has emptied, the 3-way valve (D) de-energizes, shutting off the motive pressure, and opening the vent port in the valve. This equalization cycle allows the pumping chamber (C) and the receiving chamber (A) to equalize in pressure, and the fill cycle begins again.
