Packages with air operated low pressure transfer pump.
The pump is designed to fit through the 2" bung opening on 50 and 205 l oil drums or to be mounted on a lid for open drums.
The pump is fixed using a height adjustable bung adapter. 1:1 ratio pumps are used for a clean and efficient transfer of lubricants, from their original drum to miscellaneous portable grease and oil pumps, buckets, auxiliary tanks, etc., without the risk of lubricant contamination.
An air valve or an optional pressure regulator allows the user to adjust the pump speed and the lubricant flow rate.
This is useful when filling open buckets to prevent splashing or to avoid overflow when reaching the top of a container.
