82885 / 83667
Pneumatically operated pumps for use with single-line systems
Model 82885 is an air-operated, single-stroke oil pump. It discharges lubricant on an air-powered forward stroke. The pressure is released on the lubricant line on a spring-powered return stroke through an integrated check/relief valve (3 way). Its translucent reservoir is refilled through a filler cap with strainer. The pump unit is suitable for systems with a large number of lubrication points and clocked greasing strokes.
Model 83667 offers the same features but includes a larger reservoir.
Features and benefits:
- Reliable operation
Reservoir with filler cap and internal strainer
- Suitable for use with single-line metering devices
