Alemite 7889-6 Service Manual

Description
The major components of the pump models in the
7889 series consist of a reciprocating air motor and a
double-acting pump tube. The pump tube is divorced
from the motor which:
• protects the motor from product contamination
• allows separation without product leakage
The pump tube features a dynamic primer (see Figure
3A) that enables the delivery of a variety of materials,
including lubricants. These high-pressure (40:1) pumps
contain a bung adapter [2 " NPTF (m)] that allows
operation directly from original drums or bulk
containers.*
Models 7889-6, 7889-B and 7889-C
NOTE: Models 7889-6 and 7889-C can be
hoist-mounted. Refer to the Page 2 for details.
Pump models 7889-6 and 7889-C are designed with a
pump tube length to accommodate different size
containers. See Figure 1.
* Model 7889-B is designed for remote installation.
