Pentair Superinox Single Pump Booster Pumps
Pentair Superinox booster pumps are compact pressure sets that pair a self-priming Jetinox stainless steel pump with a 24-litre horizontal stainless steel pressure vessel. Each set arrived assembled and wired with a pressure switch, a 6 bar gauge, a five-way brass manifold and a flexible connection hose. They suited flats, smaller houses, holiday lets and outbuildings where the incoming pressure was too low for a decent shower.
Both Superinox sets, the 60/50 and 90/50, have now been discontinued. The details on this page are kept for reference if you are maintaining or replacing one. For a small automatic booster, look at the Pentax PM45-A, or call us on 01252 515169 and we can advise on the best replacement for your property.
The pump is a single-stage jet pump: a Venturi tube recirculates part of the flow to create strong suction, so it primes reliably and keeps priming even with some air in the water. The pump body is AISI 304 stainless steel, the impeller is technopolymer with a stainless steel shim ring, and the mechanical seal runs graphite on ceramic. The 230v single-phase motor is IP44 rated, has Class F insulation and has thermal protection built into the winding.
Superinox 60/50 and Superinox 90/50 compared
The Superinox 60/50 uses the 0.55 kW Jetinox 60/50 pump. Pentair gives it 46 metres of head at shut-off and 31 metres at 20 litres per minute, falling to 18 metres at 40 l/min. It was sized for one bathroom or a kitchen and a shower used one at a time.
The Superinox 90/50 uses the larger 0.9 kW Jetinox 90/50 pump. It holds pressure far better as flow increases: 33 metres at 40 l/min against 18 for the 60/50, and still 20 metres at 80 l/min. It was sized for a house with two bathrooms, or where a shower and taps often run together.
Pentair sets the pressure switch to cut in at about 2 bar and cut out at about 3 bar. At 3 bar (roughly 30 metres of head at the pump) the 60/50 delivers around 20 l/min and the 90/50 around 50 l/min, which is a useful benchmark when you choose a replacement.

Head figures are Pentair’s published performance for the Jetinox pump fitted to each set; motor figures are rated output on 230v. Both models are no longer available.

Where a Superinox Booster Set Was Used
Superinox sets were for modest, everyday demand: a top-floor flat with a weak shower, a cottage on the end of a long supply pipe, a holiday let, a garden office or a stable block. Pentair lists domestic water supply, pressure boosting, washing and small-scale irrigation among their uses. The pressure vessel and switch run the pump automatically, starting it when a tap opens and stopping it when demand ends.
Because the Jetinox pump is a jet pump with strong suction, a Superinox set copes well with a tank or cistern sitting below the pump, and it can also lift from a shallow well or rainwater tank when a foot valve is fitted on the suction pipe. Our self-priming pumps guide explains how this works, and what is a booster pump covers the break tank rules that apply to most UK mains water installations.
If you are replacing a Superinox, the Pentax PM45-A is a small pump with built-in automatic control, and you can compare other options in our booster pumps category.
Frequently Asked Questions
Is the Superinox still available?
No. Both the Superinox 60/50 and 90/50 have been discontinued. Tell us how many outlets you need to run at once and where the water comes from, and we will suggest a replacement booster.
How many outlets could a Superinox run at once?
Work from Pentair’s figures at the 3 bar cut-out pressure. The 60/50 gave around 20 l/min at 3 bar, enough for one shower or a couple of taps at a time. The 90/50 gave around 50 l/min at 3 bar, so it would usually run a shower and a tap or two together. Use the same figures as a guide when you size a replacement.
Can a Superinox lift water from a tank or well below it?
Yes. Pentair recommends a maximum suction lift of 8 metres with a foot valve and strainer on the suction pipe. Keep the suction pipe short, airtight and at least the size of the pump inlet, and fill the pump with water before the first start. Our guide on how to prime a pump covers the steps.
What is the pressure vessel made of?
Pentair built the Superinox range with a 24-litre horizontal stainless steel vessel fitted with a replaceable food-quality membrane. The vessel stores pressurised water, so short draws such as hand washing are met without starting the pump.
What happens if the break tank runs empty?
The pump must never run dry, and Pentair does not list dry-running protection for these sets, so the pressure switch alone will not stop a dry pump. Fit low-level protection in the tank, such as a float switch wired to cut the pump.
