The hydraulic clamping pump is particulary suitable for small to medium-sized clamping and mounting devices having single-acting cylinders which operate primarily by intermittence (pressure build-up and pressure holding).
Description
The tandem plunger pump is built into the oil reservoir in a space-saving manner. It operates with oscillating movements and automatic stroke reversal control by a pilot-operated 4/2 valve. The stroke frequency, and consequently the delivery flow rate depend on the air pressure and the hydraulic counterpressure.
