- In detail
Yale hand pumps are easy to use and operate independently of any external energy source. They are designed for maximum 700 bar system pressure and will allow each Yale hydraulic cylinder to utilise its maximum capacity.
The two stage system reduces pumping time. Stage 1 allows rapid piston travel under no load or light load conditions. The pump automatically switches to stage 2 when the piston is loaded and a higher force is required.
The Yale hand pump is an all-steel construction designed for rough use and has a high-efficiency pumping action. The handle can be locked for easy carrying. The large and easy to control return valve allows the operator to precisely control the return stroke. Other standard features include a large and easy to control hand wheel, air bleeding and oil filling plug, large support feet for stability, tilted tank to increase useable oil volume and ergonomic handle grip.
