Balboa Ultimax UM EME 4HPR 2S HV 1 & 2 Speed
UM EME 4HPR 2S HV 50Hz BULK
Part Number 1023033
They're listed as 4HP in Australia, but are actually only 2HP, as Balboa sometimes measures the BHP for "effect."
This is a very common pump found on many Spa Industries' brands of spas. They were mostly 2-speed pumps with the low-speed wire clipped off.
Unfortunately spare parts were not made available in Australia. We have also seen a number of these pumps fail after only a year or a few.
Your best option is to purchase one of these, with spare parts and warranty:
- Single Speed
- 2 Speed
