84944 / 84961

Hydraulically operated piston pump for use with single-line systems

Model 84944

Models 84944 and 84961 are pumping systems designed to operate centralized lubrication systems that utilize single-line, parallel grease metering components. The pump is double acting, dispensing lubricant on both the up and down strokes. These units are designed for off-road equipment that utilizes 24 V DC power sources. 

These units can be used in conjunction with: Models 244270 (not potted) or 249605 (potted) cycle timers. Model 84944 hydraulically operated pump with 60 lb metal reservoir and vent valve (basic pump). Model 84961 basic pump (similar to Model 84944 but without reservoir or vent valve). These products include a pump and hydraulic control.
