The dependence of the delivery rate / lubricant container

Manufacturers deliver greases and lubricants in the most different containers and tanks. There is no standarized dimension or norm of the containers.
While pumping with pneumatic or electric pumps, the dimensions or the form of the containers have a certain importance for the right dimensions of the piston follower plate.
Conical containers or containers with large grooves can badly influence the pumping. Only special grease supply systems (Drum Pumps) should pump high viscositiy lubricants out of such containers.
The lubricant shouldn't be poured into another container. If really necessary, special criterions have to be followed. Air inlets and dirt can influence the quality of the
pumping (consult the lubricant manufacturer).
