Air-driven hydraulic pump PAY series

single-actingminiaturedouble-acting

Operating pressure max. 700 bar These mini-pumps are driven by an air-powered motor and can be connected to any supply source of compressed air. These compact low-cost pumps can operate all single-acting or double-acting hydraulic cylinders up to a max. operating pressure of 700 bar. Features & Benefits Due to large reservoirs, large cylinders or multiple cylinders can be operated. The use of an inline air filter-lubricator is recommended. The hydraulic pressure can be infinitely adjusted on the regulator of the air-lubricator unit. The air-driven motor guarantees 100 % explosion protection. Pumps for double-acting hydraulic cylinders are equipped with an additional 4-way control valve type VHH-4/3. The connected hydraulic cylinder is controlled ‒ advance ‒ hold ‒ return ‒ by the universal pedal, which can be either hand or foot-operated. Control of cylinder motion • Pedal in neutral position – motor stands still, cylinder stands, pressure is held. • Pedal depressed – motor starts, cylinder advances, pressure is built-up. • Pedal pushed forward – motor stands still, pressure is released, cylinder retracts.
