3.2. Technical Description
3.2.1. Primary Components
The primary components of the truck package are illustrated in Figures 2.1-2.3 which are as
follows:

A prime mover in the form of an industrial diesel engine which drives a Harben P Type
high-pressure pump.

The pump can produce high-pressure water up to 4000 psi.

Note: See above or section 7 for performance options .

A hydraulic driven hose reel with up to 500 feet of single wire braid high-pressure hose
with either a nozzle or gun attachment to deliver the high-pressure water to the work
application.

Plastic water tank, acting as a reservoir, also ensuring the water is settled and non-
turbulent, discharging a smooth uninterrupted supply, with a positive head of pressure
to the inlet, maximising the full potential of the pump.

The pressure valve directs high-pressure water to the main jetting hose or diverts it
back to the tank.

The control panel which includes the engine controller, pressure gauge, throttle, high-
pressure selector, jump jet valve & hydraulic hose reel controls.

A Hypro 80 micron mesh inline strainer is fitted to the suction line between the tanks
and the pump inlet.
NOTICE: This is a critical component which ensures that no contaminants are drawn
into the pump inlet. This filter must be inspected and cleaned daily, if it becomes
blocked it will cause the pump to cavitate.
3.2.2. Engine Monitoring
Engine oil pressure and hours run are monitored on the engine control panel.
