Description
The major components of model 9930 and 9979 series grease
pumps consist of an air-operated motor and a pump tube. The air
motor connects directly to the double-acting reciprocating pump
tube.
The pump tube on these high-pressure pumps (50:1 ratio)
feature a dynamic primer (see Figure 2-B) that enables the
delivery of a range of greases.

of a cover that:
• utilizes a 2 " NPTF bung adapter

camlock connection for installation onto bulk grease tanks.
* Model 9979-M contains components (See Table 1)
