Delivering strong, dependable jet performance, the Balboa Ultimax 2.0HP Two-Speed Booster Spa Pump is engineered for Australian spas that demand power, flexibility and longevity. Designed as a direct replacement for the 1023033 (blue wet end labelled 4HPR), the Ultimax uses the same barrel unions for a straightforward swap, with only a minor difference in suction and discharge thread length (approximately 5 mm shorter).

Renowned as a benchmark in spa pump design, the Ultimax range supports everything from targeted therapy seating to multi-pump, multi-jet configurations. With two-speed operation, this pump provides high-output performance for invigorating massage and a lower speed for quieter, energy-conscious circulation—perfect for everyday spa enjoyment in Australian homes.

Manufactured by Balboa Water Group, the Ultimax is built for reliability and long service life in demanding spa environments.
