SOLENOID SHIFTED AIR

DISTRIBUTION VALVE OPTION

Warren Rupps solenoid shifted, air

distribution valve option utilizes electrical

signals to precisely control your

SandPIPERs speed. The solenoid coil

is connected to the Warren Rupp

Solenoid Rate Controller/Batch Control,

or a customer - supplied control.

Compressed air provides the pumping

power, while electrical signals control

pump speed (pumping rate).

OPERATION

The Solenoid Shifted SandPIPER has a

solenoid operated, air distribution valve

in place of the standard SandPIPERs

pilot operated, air distribution valve.

Where a pilot valve is normally utilized

to cycle the pumps air distribution valve,

an electric solenoid is utilized. As the

solenoid is powered, one of the pumps

air chambers is pressurized while the

other chamber is exhausted. When

electric power is turned off, the solenoid

shifts and the pressurized chamber is

exhausted while the other chamber is

pressurized. By alternately applying and

removing power to the solenoid, the

pump cycles much like a standard

SandPIPER pump, with one exception.

This option provides a way to precisely

control and monitor pump speed.

BEFORE INSTALLATION

Before wiring the solenoid, make certain

it is compatible with your system voltage.
