Double acting hand pump for single effect cylinder

The PM20 hand pumps are lever operated pumps with 20 cm3/cycle (1,22 in3/cycle) displacement.



The PM20 hand pumps are manually operated single delivery hydraulic pumps. They are suitable for feeding single-acting or dipping hydraulic cylinders. The displacement is fixed: 20 cm3/cycle (1,22 in3/cycle). The cycle is double pumped, therefore it generates pressure in both movements of the lever and the value of the displacement is therefore referred to the operation of the pump in both directions. This type of hand pumps is particularly suitable for emergency controls. The PME20 is a pump for panel installation. The suction of the fluid from the tank occurs through the application of a tube to the inlet port. The maximum working pressure is 350 bar (5075 PSI), while the optimal one to contain the mechanical driving force is 150 bar (2175 PSI). The pump body is made of cast iron and protected externally by painting, all the other steel parts are protected externally from oxidation with a galvanizing treatment. Optional functions such as the by-pass valve are available on request. The pump is supplied with an operating lever L=600 mm.
