DESCRIPTION
Utility pump Models 7531-4 and 7531-A4 are of the
hand-operated, lever-action type.
Model 7531-4 is designed to accommodate a 35 lb.
bucket. Model 7531-A4 operates from a 20 kg
container. See Figure 1.
Application of these units eliminates hand and paddle
filling methods, thus keeping lubricant clean and free
of any contamination when being applied.
The high-pressure pump provides ample pressure to
lubricate close-fitted bearings. Lubricant delivery is one
ounce (28.4 gms) per five strokes. The dynamic primer
aids priming in cold weather and enables the pump to
handle heavier greases more readily. All pressure gun
lubricants can be used. The follower plate prevents any
channeling of lubricant.
Each unit is equipped with a cover, follower plate, six
foot (1.8 m) lubricant hose, and hydraulic coupler. The
coupler provides a quick, leak-proof contact with the
hydraulic fitting and allows a wide sealing angle
connection.
