Description

The major components of the 7175-R4
mobile "Rockcrusher" grease pump consist of a:
• 40 pound (18.2 kg) capacity container
• pressure switch controlled drive motor
• helix arm/blade and helicoid flight
priming mechanism*
• high-pressure control valve with z-swivel
and 10 foot (3 m) hose assembly
The pump delivers 14 ounces (0.40 kg) of
NLGI No. 1 grease [at 70 F (21 C)] each minute.
Heavy fibrous grease is pumped at a rate of
5-1/2 ounces (0.16 kg) per minute.

Pressure Switch

A pressure switch maintains lubricant
pressure between 3500 and 5000 psi
(241-345 Bars). This switch assembly acts as
the on/off switch during control valve operation.

Emergency Bypass System

A pressure relief valve operates as a back-up
to the pressure switch.
* This is a positive-feed design that
dispenses heavy grease at low temperatures.
