phase motor with thermal protection pressure. Mount push button switch(es) near
the operator. Push one button to clamp and

• Pressure adjustable from minimum to the unit is a precision, long-life radial-piston
maximum as shown in pump chart pump controlled upon pressure demand by
the integral pressure switch. This switch is

psi. Automatic pressure control is assured,
Multi-Pressure Pumps because the pump restarts if pressure drops.
Clamping pressure is assured even with an
electrical power failure since the solenoid
valves are mechanically held in the clamped
position - and only need power to unclamp.
The poppet design of these valves means
positive, leakage-free sealing.
