Strong and durable hydraulic hand pump with pressure and safety control valves.
HPT OTVS has built-in pressure relief valves which prevents pumping with greater force than set. At the same time the pump has the feature that if the load exceeds a specified limit, then a flow limited relief valve will be activated.
For example if a crane-arm maximum may lift 500 kg and attempting to lift 550 kg, then the pump pressure will activate the relief valve. Also if a crane arm should be loaded with more than permissible, then the crane arm will automatically be lowered safe and easy.
Oil reservoir capacity: 1.1 L (the pump is not delivered oil filled)
Pump volume: 11 cm3
Pump pressure relief valve interval: 50 - 350 bar
Load pressure relief valve interval: 50 - 350 bar
Surface treatment: zink/iron silver passivated + sealer
( #Before taking the pump in use, please turn the little shiny screw in the white cap 3600 counter clockwise to ensure a free oil-flow!) see instructions!
