Water pumps
Twelve pumps, kits and controls for tank water. The smallest runs a one-bathroom bach. The biggest holds pressure with twelve taps open.
Which pump do I need?
Most family homes want 40 to 60 litres a minute at 35 to 45 metres of head.
What tank are you pumping from?
Pressure pumps
Sits on a pad beside the tank where you can get at it. What most houses on tank water run.
Submersible pumps
Goes down inside the tank. No pump noise at the house and nothing taking up space outside.
Pump kits
Pump, cover, hose, seals and every fitting in one box. Your plumber connects it and leaves.
Mains backup
Rainwater first, town supply automatically when the tank drops. For a house that cannot be caught out.

What most homes on tank water end up with. It sits beside the tank where you can reach it, and there is one here for everything from a sleepout to a two-storey house.
Bianco
Stainless body with the nXt Core controller already fitted, so there is no separate pressure switch or bladder tank to buy. 58 L/min runs a shower, a toilet and the washing machine at the same time.

DAB
Italian-built jet pump in two sizes, up to 60 L/min and 53.8 m of head. Take the larger 102 when the water has to climb: a second storey, a long run to the house, or a tank sitting well below it.

Grundfos
AISI 304 stainless, certified to ISO 9906:2012 grade 3B, 67 L/min at 44.5 m of head. Pair it with the PM1 controller for constant pressure. The one to fit if you would rather not think about the pump again.
$1,180.00incl GST

Bianco
Six models covering 60 to 120 L/min and 34 to 72 m, so you size it to the house instead of rounding up. The extra stages give you head, which is what a long pipe run or a steep site actually needs.
From $1,350.00incl GST

DAB
Pump, variable-speed drive, sensors and pressure vessel in one enclosure, so there is nothing separate to plumb in or find room for. Speed follows demand: run two showers together and the pressure holds.
From $2,410.00incl GST
View this pumpBuy one of these and you will forget it is there. It sits down inside the tank, so there is no pump noise at the house and nothing taking up room outside. The trade-off is lifting it out to service it.
Claytech
Narrow enough to drop down a restricted tank opening, which is what catches most people out. 85 L/min and 48 m of head from inside the tank, with a float switch so it cannot run itself dry.
$920.00incl GST

Bianco
100 litres a minute and 45 m of head from inside the tank, with dry-run protection built in. Sized for a larger home with nowhere sensible to put a surface pump: the noise and the footprint go in the tank with it.
$1,150.00incl GST

Promax
Stainless-shaft submersible on an automatic float, so it starts and stops itself. 40 litres a minute, and it handles more than tank supply: garden irrigation, treated effluent and general water transfer.
$2,150.00incl GST
View this pump
Promax
Stainless-shaft submersible on an automatic float, moving 60 litres a minute. The flow to take when a garden line, a transfer job or a treated effluent system needs more water than a small pump can keep up with.
$2,500.00incl GST
View this pumpEverything the plumber needs in one box, so the job gets done in one visit. Pump, Promax cover, 2-metre suction hose, two 90 mm tank seals, ball valve, hose tail, reducing nipple and thread tape.
Promax and Bianco
A Bianco Inox 45 boxed with the Promax cover, suction hose, tank seals, valve and fittings. 58 L/min at 40 m with the nXt Core controller fitted. One box, one plumber visit, no trip back to the merchant.

$2,224.00incl GST
View this pumpFor the house that cannot be caught out. It runs on your rainwater, and the moment the tank drops or the power cuts, town supply takes over on its own.
RainBank
Runs your toilet and laundry off rainwater and switches to town supply on its own when the tank drops, so nobody has to watch a gauge. Tamper-resistant cabinet with backflow protection built in.
$3,750.00incl GST

Flow and head are manufacturer maximums. What you actually get depends on pipe size, pipe run and lift. The kits carry the figures of the pump inside them: Bianco Inox 45 in the Economy, Grundfos JP 4-47 in the Premium. Prices include GST. To have it sized against your own layout, call 0800 77 66 29 or run the pump selector tool.
A cover keeps the weather off a pressure pump and quietens it down. The collection kit keeps leaf litter out of the tank in the first place.
Questions
Sizing, fitting, delivery and whether it is safe for drinking water.

The tank decides it:
After that it comes down to flow and head. The next two questions work both out, or the pump selector tool will do it for you.
Flow, in litres a minute. Add up what might run together:
A bach or a sleepout runs fine on 20 to 30. A three-bedroom house wants 40 to 50. Two bathrooms and outside taps, 60 or more.
Head, in metres. Measure from the tank outlet to your highest tap or showerhead, then add for long horizontal runs, because they cost pressure too.
A single-storey house near the tank is comfortable on 35 to 45 metres. A house well above the tank, or a tank a paddock away, needs more.
A standard pump switches on and off at set pressures. That is what most houses run and it is fine.
A constant pressure or variable speed pump varies its speed to match demand, so the shower does not drop away when someone flushes the toilet. It costs more up front. Worth it if you have two bathrooms, or if you have lived with pressure drops before.
Same fittings, different pump.
Constant pressure is the real difference. The shower holds when a second tap opens.
For a new above-ground install, take the kit. It has the pump, a Promax cover, the suction hose, the tank seals and the fittings, so nobody is driving back to the merchant halfway through the job.
If you already have the fittings, both kit pumps sell on their own: the Bianco Inox 45 and the Grundfos JP 4-47.
For a pressure pump, yes. Both kits include one.
Take the large cover if your pump has a pressure tank. A submersible does not need one.
Run a pump dry and you will damage it, and tanks do get low over a dry summer. Every pump here comes with dry-run or low-water protection, either in the controller or through a float switch, and the method is on each product page.
Part of it. A competent DIYer can connect a kit: the tank seals, hose, valve and fittings are in the box, and the controller comes fitted to the pump.
Much of the range is approved to AS/NZS 4020 for contact with drinking water, and it is noted on the product page where it applies.
If it matters for your job, tell us before you order and we will confirm it for the model you are looking at.
If you are ordering a tank at the same time, tell us and we will check whether the pump can go on the same delivery.
Not sure which pump suits the tank you have chosen? Ring us and we will match it.
