Default RE: Replacing Speed 400 4,8V

The pump is a direct drive, i have no gear whatsoever. That is why i'm trying to "beat" the 22000rpm @ 4,8V of the speed.

I've also found a supplier who gives some engine data to calculate with (rpm constant, resistance, idle amps etc...). Judging from the numbers i'll probably end up around 10x2. I'll order a set of motors in that range and see what i can do with them....

Thanks a bunch
best regards
