A demonstration video created by Performance Garage & Davies Craig on our Electric Water Pump (EWP) and Digital Controller. We also highlight the various EWP’s available in the rage including the EWP80, EWP115 Nylon and EWP115 Alloy. We also discuss our latest product, the EWP Header-Adaptor Kit and its applications. The video concludes with an actual demonstration of the EWP and Digital Controller in application.
Why the power the EWP uses is much less than the mechanical pump
The EWP is designed for maximum efficiency at its maximum speed of 2250 rpm. Being in nylon, the impeller can have aerofoil cross section with associated lift, and the tip clearances can be very small. The mechanical pump has to run at 600 rpm and 6,000 rpm and it cannot be efficient at both those speeds and all speeds in between. Furthermore, as the power the pump takes increases as the cube of the speed – when the mechanical pump is operating at the higher speeds, as it does as an engine passes through its gears, it is taking power of the order of 6 to 10 kW. The EWP which uses say at maximum speed 9 amps x 13 volts gives 120 watts at say 30% efficiency from the alternator to hydraulic power means about 0.4 kW to drive the EWP, when it is operating at full speed which is usually less than 20% of racing time.
In addition, with the old mechanical pump and a thermostat set up, the thermostat is partly closed most of the motoring time and in a cool climate at highway cruising, it is always about 90% closed. As a consequence, the flow and pressure being generated by the mechanical belt driven pump and paid for with power and torque, are choked at the thermostat and wasted. This system has worked reasonably well for a long time but it is not smart. With your EWP and digital Controller, power and torque is never wasted as there is no choking (no thermostat) and only as much flow and pressure as is required is produced.
We are starting to see the allowance of EWPs in formula racing mostly to prolong the life of engines with the run on after hot shut down to eliminate heat soak. In any case we cannot stop progress, nobody in racing runs drum brakes or cross ply tyres these days!!
