Triple & Quad Base Classic Pump Options

ES

Energy Saver - Assembly includes non-return valves and air pilot supply valves controlled via one adjustable pneumatic vacuum sensor to cycle the entire pump off when a preset vacuum level is achieved and back on when the vacuum level decreases. Primary pump control is via on remote air pilot signal and a maintained air supply to the pump base inlet port. Suited for non-porous or volume tank applicatoins. A quick release valve (RP, RS) should also be specified.

AV

Automatic Variable Capacity - Configuration where air pilot valves are controlled via one remote air pilot signal plus adjustable pneumatic vacuum sensor to switch on/off sections of the pump as required by the sensor settings. One station of a triple and two stations of a quad pump remain active at all times. Non-return valves are included and a quick release valve (RP, RS) should be specified. Suited for both porous and non-porous applications or for any application where the system duty cycle includes high flowrate "roughing" plus long holding periods of high vacuum with lower flow rate requirement. Leakage or porosity losses during high vacuum phase are compensated for by the stations remaining active.

RP & RS

RP - Quick Release Piloted - A two-way valve is controlled via remote air pilot signal. Used to admit a burst of compressed air into the base vacuum chamber to quickly release a work piece and to momentarily reverse flow through filter elements to provide a cleaning action. This option requires a maintained air supply to the pump base inlet port.

RS - Quick Release Solenoid - A two-way valve is controlled via solenoid valve. Used to admit a burst of compressed air into the base vacuum chambers to quickly release a work piece and to momentarily reverse flow through filter elements to provide a cleaning action. This option requires a maintained air supply to the pump base inlet port.

Weight = 0.53 lbs. (0.24 kg)

CE

Captured Exhaust Option - To specify, add suffix "CE" to pump model code. Use with 3" (75 MM) I.D. hose. Add 0.86 lbs. (0.39 kg) to total pump weight.
