Yale PAY Mini Hydraulic Pumps, w/Compressed Air Driven Motor

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.
