With Adjustable Overload Relief Valve
With Manual Pressure Release Valve
Without Reservoir

These Single-Piston pumps are solid, heavy-duty, versatile manual pumps that are to be used with a hydraulic system having a built-in reservoir.  These pumps are available in base or flange mount and include both adjustable overload valves and pressure relief valves.  The standard model provides a simple screw pressure release valve for a controlled lowering speed.  An easy to use CAM pressure release valve is also available for a time-saving method to release pressure.  Other options are available including, foot operated models, stainless steel versions and 4 way valve models.
 
Features:
  • Multi-use pump for developing or increasing hydraulic pressure
  • Factory set overload relief valve
  • Manual pressure release valve with screw, cam or foot release
  • Provides pressures up to 10,000 PSI
  • Supplied with a 24" operating handle or foot lever

Options:
  • Base or Flange mount
  • Hand or Foot operated lever
  • Screw, CAM or Foot activated pressure release valve
  • Standard steel or Stainless Steel versions
  • Lower Pressure setting if customer specified

    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.
