2ES Clasic Pump

Energy Saver Option

The pump includes a non-return valve and an air piloted supply valve controlled via an adjustable pneumatic vacuum sensor. The vacuum sensor cycles the pump off when a preset vacuum level is achieved and cycles the pump on when the vacuum level decreases from the preset level. A regulated air supply is connected to port 1 (Air Supply - Main) and the pump is controlled by a positive pilot signal to port 4 (Pilot Signal - Air Control). The energy saver control will operate only when the pilot signal is present. Best suited for non-porous or volume tank applications. Because of the non-return valve, a quick release valve (RC18A) or some other means should be provided for dissipating the vacuum.
