3.2. Technical Description
3.2.1. Primary Components
The primary components of the 320 Series Desilter Vanpack are as follows:
1. A prime mover in the form of a Kubota 3-cylinder water-cooled diesel engine which
drives a Harben P type high-pressure pump.
2. The pump is capable of raising the water pressure up to 2900psi (200 bar).
3. A Hydraulically driven hose reel c/w 91.44 m (300 ft) of 2 wire braid high-pressure hose
with either a nozzle or gun attachment to deliver the high-pressure water to the
selected working site.
4. A plastic water tank 085-271, acting as a reservoir, ensures the water is settled and
non-turbulent, discharging a smooth lamina flow of uninterrupted air free supply, a
positive head of pressure to the pump inlet and maximising the pumps full potential.
The tank can be filled via the inlet reel by connecting to a mains inlet water supply
Note: Turbulent water will cause the pump to run unevenly and cause excessive wear
due to cavitation.
5. Water is diverted to the hose reel either using a 12VDC hydraulic diverter.
6. A Hypro 177Micron mesh inline strainer is fitted to the suction line between the tank
and the pump inlet.
Note: 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 engine coolant temperature, together with alternator charge rate are
continuously monitored. Activation of the engine pressure or temperature switches will cause
an engine shutdown and the respective ‘FAULT’ to be displayed on the control unit.
Alternator failure will be displayed on the control unit.
3.2.3. Delivery Hose Reel
The hose reel drum on which the delivery hose is wound is driven by a powerful OMR315
hydraulic motor directly coupled to the hose reel hub. Hydraulic power is obtained from a
hydraulic gear pump driven from the engine P.T.O. (See below)
