High-Pressure Bulk Grease Pump
Description
The major components of pump model 7730 consist of an air-
operated motor and a pump tube. The air motor connects directly
to the double-acting reciprocating pump tube.
This high-pressure (75:1 ratio) grease pump is designed to
deliver a range of greases [up to NLGI # 3] directly from bulk
containers.
Mounting
In most cases these pumps connect horizontally to a bulk
container. See Figure 6. The pump includes the male portion of a
3-inch camlock connection for ease in installation.
Distribution System
The use of the proper equipment that comprise the entire
product distribution system is essential.
All components must have a pressure rating that allows safe
operation at the maximum anticipated pump pressure.
