If the pump is supplied with clean, dry air then there is no need for lubrication. If the pump is isolated or installed in a place away from the operator then any mineral or synthetic oil will ensure long lasting efficiency. Two drops every 4 hours of operation will suffice.
Roughneck Air-Operated Grease Pump, 50:1 Ratio, 150 PSI, Fits 120-Lb. Drums

I already have grease gun and hose and grease barrel . What else besides the grease pump would I need to purchase? Any help would be greatly appreciated. Thank you

It would need to be connected to an air compressor. It has a 1/4" air inlet and requires a maximum 150 PSI air inlet pressure.

does this pump fit the drum lid treads
1 answer-
RoughneckExpert11· 3 years ago
The pump does not come with lid threads. It will come with a drum cover along with thumb screw which will fit a standard 50 Kg (110 lb.) drum.
