1:65 ratio air-operated grease pump 0102093-0102095

For pail, 1/4-drum or 1/1-drum, with drum bung fitting for lid mounting. The grease pump can be equipped with a special follower plate for almost completely emptying the grease barrel. The pump, when used with automatic centralized dual-line lubrication systems, is equipped with a return line connection to return grease to the barrel below the follower plate. This type of system is common in e.g. paper, pulp, steel, and cement mills, mines, and power stations etc.

It is virtually impossible to empty a grease drum completely by means of a conventional pump and follower plate. Our pumping innovation is the “Totally Empty Concept”. It challenges conventional construction because the pump is supported on a floating follower plate. This follower plate/pump construction is designed as a completely closed grease handling system to empty a grease barrel. Only the grease remaining under the curved follower plate (circa 1.5-1.9 kg in a 180/200 kg drum) is left in the barrel. The pump and follower plate fall with grease level due to the weight and the vibration caused by the pump, in combination with the vacuum that arises under the follower plate preventing the plate from sticking in the drum. See fig. 1.
When the drum is empty, the follower plate rests hard against the bottom of the drum and must be released by means of compressed air via the airgun (Part Number 902947). See fig. 2.
In addition the pump when used with a centralised lubrication system is designed with a return line connection to return grease to the barrel below the follower plate.
