Hi guys,

Here is what we used: I did reuse the flowjet pump and replaced the motor by a brushless scooter motor. These motors are very strong and got no wear parts except the ballbearings for less then 2 euros. I mounted the motor on an L shaped 6mm aluminium and the pump from the oposite side. The D shaped 8mm shaft is the same like the original flowjet shaft. The motor is driven by 60% speed and works flawless while over sized. It takes less ten 1A at 24 V pushing 10 liter per min. The motor does not get warm at all = no wasted energy, as before. It would be possible to controll the wateroutput according to raw water temperature. I did not use this feature jet. To drive a brushless motor, it needs a speedcontroller. I used the VESC for it, also way oversizedwhile capable to controll high currents. We connect the 24v batterie directly to the VESC. No more using step down to 12 V wasting more energy. The motor/pump speed is open to be controlled from 0 to 100% € 50,91 | ESK8 6368 BLDC outrunner bürstenlosen motor 190KV 280KV sensored sensorlose 22-48 V für elektrische balancing roller e- skateboard https://s.click.aliexpress.com/e/2Yrn2Uz6 D-shaped shaft 190 kv, shaft has 8mm diameter, sensored. € 55,36 36%OFF | FSESC 4,12 50A Basierend auf VESC 4,12 Elektro Speed Controller für Skateboard/E-roller Zubehör Flipsky https://s.click.aliexpress.com/e/rkgt1kV2 We use it now without any failing pump anymore.
