Operational Overview
Supply water is introduced through the 1/2-inch NPT connection on the bulkhead of the pump
and is routed to the normally closed solenoid valve.
When the pump is started, the solenoid valve opens and allows water to flow through the valve.
The inlet water pressure is displayed on the pre-filter pressure gauge on the control panel.
The water passes through the coarse filter assembly and is routed to the subplate to cool the high
pressure cylinders. When the water returns from the subplate, it passes through a fine filter and is
sent to the low pressure manifold.
