These hand pumps boast a large oil capacity to power a wide range of cylinders or tools. A two-speed operation is incorporated for reduced operator fatigue (except on P-39).
A 4-way valving on the P-84 and P-464 is for operation of the double-acting cylinders.
In addition, the pumps have an external load release valve on remaining models for single-acting cylinder operation.
An internal pressure relief valve for overload protection is also included.
