Alemite 7735 Service Manual

Medium-Pressure Bulk Grease Pump
Description
The major components of pump model 7735 consist of an air-
operated motor and a pump tube. The air motor connects directly
to the double-acting reciprocating pump tube.
This medium-pressure (10:1 ratio) grease pump is designed to
transfer a range of greases [up to NLGI # 3] from their original
bulk containers to smaller containers.
Mounting
In most cases these pumps connect horizontally to a bulk
container. See Figure 5. The pump includes the male portion of a
3-inch camlock connection for ease in installation.
Material Delivery Hose and Control Valve
The use of the proper size delivery hose and control valve (if
used) is essential to optimize flow rate. A hose that is excessively
long or with too small an inside diameter will restrict product
flow.
Both components must have a pressure rating that allows safe
operation at the maximum anticipated pump pressure.
