I am using a bmw electric water pump on my hot rod.
Bmw electric water pump flow rate.
7 03665 66 0 7 02881 66 0 bmw.
If i leave 2 connected to 12vdc continuously the pump runs at high speed.
Older ones use pump with 480w power for newer engines the power of it reaches 700w.
12vdc to 4 wire.
Product range application.
Petrol engines of n series uses electric water pump.
Everything looks nice communication via serial interface control of all temperature load self diagnostics etc parameters intelligent management but.
The pump pressure or differential pressure expresses the resistance of which the pump has to work against.
I connected 12vdc to 1 wire.
150l min 0 85bar 220l min 0 55bar protection.
Those pumps can of course be used in normal automotive cooling systems with system pressures in the range of 0 8 to 1 2 bar for instance.
Pump pressure is not the same as the system pressure.
The best benefit for aftermarket and motorsport application would be the freedom of installation and use.
This knot also isn t without oddities.
