Pump 87212 with hydraulic drive

For sequential lubrication systems

The Model 87212 is a single-acting pump with a double-acting hydraulic cylinder, requiring a 4-way valve and timer for operation. Hydraulic pressure acts on the piston during the delivery stroke and returns it to the fill position. Depending on the reservoir used, the pump is suitable for both grease- and oil-lubricated components. The Model 87212 requires a specially designed reservoir, which must be ordered separately.

Technical characteristics and advantages

  • The pump can be removed from the tank without disturbing the configuration of the pipelines used
  • An inlet shut-off valve at the base of the tank allows the pump to be removed without emptying the tank.

Application areas

  • Small-sized sequential systems
  • Foundry equipment
  • Metal forming
  • Metal cutting
