Planetaries for inline jung pump connection

[Rimrock]

Yeah, 2-3000 rpm is alright for a Jung pump. If you don't mind the noice of a 1600KV motor, if may not be a problem...will likely deal with 150-175 degrees for some time. but...lower rpm is always a bit better in the long run, when it comes to such equipment. I'm about to mount a 400KV motor to a Jungpump. I just can't stand the screaming of many of those brushless motors and managed to find bit quite one. But need to but a transmission in there anyway. If going for 1:1 ratio, the motor would just be too big.
