Air Driven Pump

PRINCIPLE:
Oil pressure is intensified due to the area ratio of air piston & oil piston. As the air
piston moves towards the end position, pressurized air input is diverted & is used for pilot operated pneumatic direction control valve. Due to this arrangement, air piston is reversed at both ends. Hence this system is self-reciprocating & acts as pump. Two check valves are used in suction & delivery line.

OPERATION:
Clean & lubricated air is connected to "Hy-Power" air driven pump. Pump reciprocates to give oil output till full pressure is reached. By changing hydraulic direction control valve position, pump reciprocates to operate cylinder till full pressure is reached. In case of oil leakage & pressure drop, pump operates to compensate the pressure drop.
