Description
The Pentair Superinox 90/50 (code 022-464) is the larger of the two Superinox automatic booster sets, built around the 0.9 kW Jetinox 90/50 stainless steel self-priming pump. Pentair gives the pump 50 metres of head at shut-off, 33 metres at 40 litres per minute and 20 metres at 80 l/min. It runs on 230v single-phase supply and draws 7 A.
At the 3 bar cut-out pressure it delivers around 50 l/min, more than twice the Superinox 60/50, so it will usually run a shower and a tap or two together in a house with two bathrooms.
Every Superinox set is built around a Jetinox self-priming jet pump, in which a Venturi tube recirculates part of the flow to give strong suction and reliable priming. The pump body is AISI 304 stainless steel with a die-cast aluminium motor support, the impeller is technopolymer with a stainless steel shim ring, and the mechanical seal is graphite on ceramic with NBR gaskets. The 2-pole motor runs at 2850 rpm, is IP44 rated with Class F insulation, and has thermal protection and the capacitor built in. The set comes assembled and wired, with a 24-litre horizontal stainless steel pressure vessel, a pressure switch set at about 2 bar cut-in and 3 bar cut-out, a 6 bar gauge, a chrome-plated five-way brass manifold and a flexible connection hose.
Pentair recommends a maximum suction lift of 8 metres with a foot valve, and rates the Jetinox 90/50 pump for a maximum operating pressure of 6 bar. Its seal holder plate is stainless steel, a difference from the smaller Jetinox pumps.

- Small commercial washrooms and kitchens
- Boosting from a break tank, or lifting from a tank below the pump
For clean water without suspended solids or abrasive material, up to 50°C. This is a cold water booster for modest demand: it must never run dry, the motor is IP44 so it needs a dry, frost-free location, and in the UK it should not be connected directly to the mains supply pipe without the water supplier’s consent, so it normally draws from a break tank or cistern.
