Yes PDI we used the middle core plug of both side because only this is to rich
there we place one M40x1,5 thread into. On place of the waterpumpe comes
a plate.

Performance of the single pumpe is max.9000 l/h or as redundant system max.18.000l/h.
We can offer 12V and 24V pumps. Material hoses : rubber, pipes : stainles steel, pump :
alloy.

The Mechanical Water Pump is one of the last mechanical components of the modern engine which has long been considered an inefficient component that was designed as an accessory from the ever first engines. A mechanical belt driven pump installed on your car engines runs at the same speed as the engine regardless of how hot the engine is. Example: when travelling at high speeds down the freeway, the engine require less cooling as ram air is naturally cooling the engine however, the engine speed is high as is the mechanical water pump thus providing excessive cooling whilst draining the engine of power. Then in heavy traffic in high ambient, the engine is idling or slow and so is the belt driven mechanical pump, even though in this condition, extra coolant flow is required to cool the engine.

With an EWP and a digital controller, the speed of the pump is managed by the controller, which varies the supply voltage to the pump and so varies the speed of the pump, hunting for a target temperature. When the engine reaches the target temperature the controller locks on, constantly changing the pump speed with traffic and throttle conditions, maintaining the target temperature independent of the engine speed.

The important improvement for your vehicle comes from the fact that most of the power the mechanical pump takes from the engine can be reclaimed with the use of an ele.water pump hence the fuel savings. By removing the parasitic power losses of belt-driven water pumps, the ele.water pump may provide up to 10kw of extra power and additional fuel savings. The engine power used by the mechanical pump increases as the cube of its speed – so when the mechanical pump speed doubles from idle speed say; 600rpm to 1200 rpm, the power it takes increases by eight times. Then another eight times going to 2400 rpm, and so on up to maximum engine speed. It is this extra power and torque that is released by deleting the mechanical pump that provides the fuel savings that is estimated to be 3.5% to 10%.
