82653/55, 83800/34

Pneumatically operated pump for use with single-line systems

Model 82653

All models are air-operated, positive-displacement pumps delivering a maximum volume by means of a single stroke of the pump. Solenoid air valves and adjustable, solid-state time controls are integrated into the pump body. These pump units are designed to deliver grease to single-line metering devices and include a special high-volume refill fitting.

Translucent, acrylic reservoirs with spring-loaded followers are available in several sizes. Pump uses air for forward and return stroke but dispenses lubricant on forward stroke only. Return stroke releases pressure on the lubricant line through included check/relief valve.

Features and benefits:

  • Remote system components such as 4/2-way valves, adjustments for air power, and monitoring of pump and system are available separately on request
  • High-volume refill fitting
  • Suitable for use with single-line metering devices
