P720

N° 5 PRESSURE RATIOS

This model of pneumohydraulic pump, complete with internal circuit for operating single-acting cylinders, is very widely used in the supply of automatic production, manufacturing and testing systems. It can be controlled by means of a handwheel on the pump (P720/M version), or with pneumatic remote control (P720/A version) and cuts out when the maximum hydraulic pressure is reached, charging the circuit, before restarting automatically if headlosses due to leakages interfere with the equilibrium. With these characteristics, it is particularly ideal for supplying clamping cylinders, with pressure ranges from 20 to 700 bar in the 5 intensi cation ratios. In the standard model, the tank has a working capacity of 1.2 litres.
