Without Reservoir

These Star single piston base or flange mounted pumps are supplied without oil reservoirs for use on equipment having a built-in reservoir. Hand operated P-LR and P-PL series pumps are available with either a screw pressure release valve for a controlled lowering speed, or an easy to operate cam release for a fast, time-saving lowering speed. Hand pumps are supplied complete with operating levers.
Maximum pressure of the hand pump is 10000 PSI. The adjustable overload will be set at the maximum pressure at the factory unless a lower pressure is specified by the customer. The overload can be adjusted by the customer in the field, if required.

    Limited Warranty

    All Star pumps are covered by a limited warranty on materials and workmanship for one year from the date of manufacture. Star will repair or replace at its option any pump in which Star finds manufacturing defects. In order to get warranty service a pump must be returned to the Star plant freight prepaid with a written explanation of the problem.

    Technical Data

    Light hydraulic oil is recommended for use with Star pumps. Oils with SUS viscosity of 75 to 150 at 100 degrees Fahrenheit will give satisfactory performance (ISO grade 15, 22, or 32). In an emergency situation when the above oils are not available, use 5 W or 10 W motor oil or automatic transmission fluid.
    All exposed surfaces of standard Star pumps are painted with one coat of industrial quality paint. Pumps painted with special colors with two coat finishes, or with prime coat only, and pumps with special plated or polished parts, are also available.
  • 1 Adjustable overload will be set at maximum unless a lower pressure is specified by customer. Add specified pressure in PS at end of Model No. Example: P1A-LR-8000.
  • 2 PL Pumps do not have threaded inlet ports. They must be gasket mounted to reservoir.
