Description
The major components of the 331378 series pumps
consist of an air-operated motor and a pump tube. The air
motor connects directly to the double-acting reciprocating
pump tube.
These high-pressure (70:1 ratio) pumps are designed to
deliver a range of light to heavy lubricants directly from their
original drum.
Models 331378-A1, B1, E1, F1, and H1
Each pump model is designed with a pump tube length to
accommodate different size containers. See Figure 1.
The difference in the length of the pump tubes for the two
12.5 kg models is due to the design of the cover.
Model 331378-E1 bolts to a cover with a flat design
(Obsolete). Model 331378-F1 uses a cover with a bung
adapter. See the section entitled Accessories for details.
