87212 pump
87212 pump

The model 87212 pump is a hydraulically operated, single-acting pump with a double-acting, hydraulic cylinder that requires a four way valve and timer for operation. Hydraulic pressure powers the piston on the delivery stroke and returns it to priming position.
Depending on the type of reservoir used, the pump is suitable for both grease and oil applications. The 87212 pump requires a specially designed reservoir that must be ordered separately.

Features and benefits:

  • Pump can be removed from reservoir without disturbing existing piping
  • Inlet shut-off valve in reservoir base allows removal of pump without draining reservoir
