Pumps for the house, the farm, the pool and the bore

Alongside the WEG motor range we supply Onga household, rural and drainage pumps and pressure tanks, the full Pentair pool and filtration line-up, Caprari bore and wastewater pumps, Orange Pumps drainage and grinder units, and Southern Cross vertical multistage sets. Because we know the motor side inside out, we can advise on the whole set — not just the wet end.

A sample of the range

What goes out the door most

A dozen of the pumps and systems we are asked for week in, week out. The full range for each brand is a click away.

Onga JS Series stainless steel jet pumpOnga

JS Series

Jet-assisted Homemaster with a stainless steel casing and base, so it survives sitting in the wet spot beside the tank. Loss-of-prime protection on JSP models.

  • 7.6 m suction lift
  • Stainless casing
  • Italian built
Onga Intellimaster variable speed pressure pumpOnga

Intellimaster

Variable speed pressure pump with an LCD display and constant pressure control. Uses markedly less power than a fixed speed pump and runs quieter with it.

  • 750 W – 2.2 kW
  • Variable speed
  • ECO SELECT rated
Onga OPT steel diaphragm pressure tanks in a range of capacitiesOnga

OPT Pressure Tanks

Onga's OPT steel diaphragm tanks, sized for domestic and industrial pressurised water storage. Adding one cuts the start-stop frequency of the pump, which is what usually kills it — and it trims the power bill at the same time.

  • 8 – 100 L
  • Steel diaphragm
  • Potable water
Onga Farm Master OJ800 cast iron jet pump with pressure tankOnga

OJ800 Range

The flagship Onga Jet, supplied complete with a pressure tank. Coated cast iron housing and precision internals — the one to fit when the bore is deep and the duty is daily.

  • 49 m deep well lift
  • Cast iron
  • Pressure tank included
Orange Pumps SP-420 submersible multistage pressure pumpOrange Pumps

SP-420

Twin impeller submersible built for pressure rather than volume — the one to reach for on irrigation, mains water divert and rain harvesting where a drainage pump runs out of head. Dual carbon ceramic seals in an oil bath and a fine grade suction screen.

  • 550 W
  • 95 lpm · 32 m head
  • 1″ automatic
Orange Pumps SPG-750 submersible sewage grinder pumpOrange Pumps

SPG-750

Heavy duty sewage grinder for caravan parks, sporting clubs, agricultural slurry and wastewater transfer pits. A 360° grinding plate and a three-blade impeller macerate organic solids before they reach the 2 inch outlet.

  • 750 W grinder
  • 165 lpm · 20 m head
  • 25 mm soft solids
Southern Cross PVMI vertical multistage pump systemSouthern Cross

PVMI / PVMIE

Vertical multistage pump system for commercial, industrial and rural water supply. All wetted parts are grade 304 stainless (316 optional), on a standard IE3 TEFC motor with a DIN 24960 mechanical seal and silicon carbide product-lubricated bearings.

  • 304 stainless wet end
  • IE3 TEFC motor
  • Vertical — saves floor space
Onga VF150 cast iron submersible drainage pump with float switchOnga

VF150 / VF150N

Single phase drainage pump in a cast iron body, designed for clear or grey water carrying some soft solids. Float switch fitted, moisture sealed cable inlet, and a vortex impeller that passes 15 mm without complaint.

  • 350 W
  • 150 lpm · 7 m head
  • 15 mm soft solids
Onga CSM240VF cast iron submersible vortex pump with float switchOnga

CSM240 Vortex

Rugged cast iron dewatering pump with a dry motor design, dual mechanical seals in an oil chamber and automatic thermal and mechanical overload cut-out. Built for pits, water treatment circulation, grey water and commercial ponds.

  • 0.4 kW
  • 250 lpm · 10 m head
  • 10 mm free passage
Pentair IntelliFlo 2 VSF variable speed pool pumpPentair

IntelliFlo 2 VSF

Variable speed and flow — it holds the flow rate you programmed as the filter loads up, instead of drifting. Up to 90% energy saving against a single speed pump.

  • Up to 90% saving
  • Programmable flow
  • 8 speed presets
Pentair Everpure EF Series undersink drinking water systemPentair

Everpure EF Series

The commercial filtration standard behind a lot of restaurant water, in a domestic undersink form that feeds the existing tap — no second faucet needed.

  • Lead and chlorine reduction
  • NSF/ANSI 53 cyst rated
  • No extra faucet
Caprari E Series submersible borehole pumpCaprari

E6 ÷ 22 Series

The core Caprari borehole range, covering 6″ through 22″ bores with the hydraulic staging matched to the head and flow the bore will actually deliver.

  • 6″ to 22″ bores
  • Multistage
  • Water supply and irrigation
Onga Farm Master OJ700 cast iron jet pump

Household, rural and aquaculture pumps

Onga

Onga has been moving water around Australasian homes and farms for over sixty years — pressure systems, jet pumps and rainwater controllers built to be lived with rather than babied. We carry the range across household, Farm Master rural and aquaculture duty.

See the Onga range
Pentair IntelliFlo 2 VSF variable speed pool pump

Pool, spa and water treatment

Pentair

Pentair covers both ends of the water business for us: the pool equipment pad — pumps, filters, heating, sanitising and automation — and the domestic and commercial filtration side, from undersink drinking water through to UV disinfection and softening.

See the Pentair range
Caprari E Series submersible borehole pump

Bore, sewage and industrial pumping

Caprari

Caprari has been building pumps, electric pumps and submersible motors in Modena since 1945. This is the heavy end of what we supply — borehole sets, solids-handling wastewater pumps and vertical lineshaft units for civil and industrial duty.

See the Caprari range
Orange Pumps SP-420 submersible pressure pump

Submersible drainage, pressure and grinder pumps

Orange Pumps

Australian-designed submersible pumps for the jobs that chew through cheaper units — sumps, transfer pits and screened wastewater. Heavy-duty wide voltage motors, seals in an oil bath and ten metres of rubber cable as standard.

See the Orange Pumps range
Southern Cross PVMI vertical multistage pumps in three frame sizes

Vertical multistage pump systems

Southern Cross

Where a domestic pressure pump runs out of road — commercial buildings, water treatment plants, fire duty and rural supply schemes. Vertical multistage sets with stainless wet ends, built to a duty point rather than pulled off a shelf.

See the Southern Cross range

Need a pump sized or replaced?

Tell us the flow, the head and what you are pumping — or just send a photo of the one that has died. We will match the pump and the motor together so the set actually performs on site.
