Hand Pump with Reservoir comes with an in-built check valve and pressure reducing system. The Hand Pump has its own reservoir and is offered in piston type design, where piston is actuated by a cam, integral with the handle of the pump. The Hand Pump is designed in such a way that as the pulling force on the handle is released, the piston returns back by spring force and the pressure in the lubrication line is reduced to 1kg/sq.Cm and so on. Hand Pump with Reservoir is also equipped with relief valve, which safeguards it from overloading.
