Description
The major components of the 8702 series pumps consist
of an hydraulic reciprocating motor and a double acting pump
tube.
These hydraulic pumps are designed to deliver a range of
light to heavy lubricants directly from their original
container.
The follower tube contains a 1/4 " NPTF (f) inlet to allow
the return of lubricant to the container when relieving system
pressure.
Each pump model is designed with a pump tube length to
accommodate different size containers. See Figure 1.
