Scope of Supply
2.1. Scope of Supply
Unit: U.S. Vanpack
2.2. Pump Assembly
Figures 2.1-2.2 defines the components of the vanpack assembly as follows:
The pump is driven by an industrial diesel engine.
The engine drives the pump via a 2.21:1 reduction gearbox which reduces the pump rpm
down to the correct shaft speed.
Water is fed from a mains supply into a plastic water storage tank. The tank supplies
the pump with a positive head of pressure via an inline hypro strainer that filters the
water to approximately 80 microns.
The ‘P’ Type 8 22 radial piston high-pressure diaphragm pump is driven by an
industrial diesel engine through a 2.21:1 reduction gearbox.
The water is directed by a divert valve, to a hydraulically driven hose reel with up to 500 feet
of ½” hose, or at low pressure ‘dumped’ back to tank.
The system is protected from over pressurization by a safety relief bursting disc.
The engine and system pressure can be monitored at the control panel situated at
the rear of the vanpack.
