Bmw Electric Water Pump Flow Rate

I am using a bmw electric water pump on my hot rod.

Bmw electric water pump flow rate.

12vdc to 4 wire. Petrol engines of n series uses electric water pump. 150l min 0 85bar 220l min 0 55bar protection. The pump pressure or differential pressure expresses the resistance of which the pump has to work against.

This knot also isn t without oddities. If i hold a 12vdc to 2 connector wire for 3 seconds and release it the pump runs at a slow speed. Older ones use pump with 480w power for newer engines the power of it reaches 700w. Everything looks nice communication via serial interface control of all temperature load self diagnostics etc parameters intelligent management but.

I connected 12vdc to 1 wire. Pump pressure is not the same as the system pressure. Product range application. The best benefit for aftermarket and motorsport application would be the freedom of installation and use.

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. How have bmw overcome the weakness in the electric water pump flow for the 300bhp 335i motor or are they not expecting people to be thrashing it flat out untill it s out of warranty. 7 03665 66 0 7 02881 66 0 bmw.
