Temperature range:
-20 to +65 °C
Connection thread:
NPT 3/8" (FT)
Scope of delivery:
The pumps are delivered filled with HLP oil.
Note:
The cost-efficient single-stage hand pumps deliver a fixed, small volume of oil per stroke regardless of the operating pressure and are therefore suitable for occasional use. The two-stage hand pumps, on the other hand, supply a large volume of oil during the unpressurised idle stroke of the cylinder and only switch to the high-pressure stage when the operating pressure is reached. In the high-pressure stage, the two-stage hand pumps (like the single-stage pumps) then pump a fixed, small volume of oil per stroke. Use of a two-stage pump can save a lot of time and physical labour depending on application.
Advantages:
•robust full metal construction ensures strength and a long service life - Welding sparks do not burn through, •the pump is equipped with a safety valve and a check valves, •a large control valve button simplifies the precise, slow relieving of the load.
