OPERATING PRINCIPLES: The heart of

switch(s) the unit is a precision, long-life radial-piston
pump controlled upon pressure demand by
• Pressure adjustable from 1500 to the integral pressure switch. This switch is
maximum adjustable, to give you precise and repeatable
clamping forces. Automatic pressure control
• Quiet long life radial piston pump
is assured, because the pump restarts if
• Filler breather with inlet screen pressure drops. Clamping pressure is assured
even with an electrical power failure since the
• Leak free fittings and poppet valves
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.
