Submersible bore pumps are the workhorses of rural and regional Australia, and choosing the wrong one is an expensive mistake we see every week. At Pumptastic, we stock over 160 Grundfos submersible bore pumps for every bore depth, flow rate and power supply in the country, from a 3 inch domestic bore behind a Perth home to a three phase irrigation bore on a Wheatbelt farm. Every pump ships fast Australia wide, with free shipping on orders over $100, and our pump specialists will size your submersible bore pump over the phone before you spend a cent. Call (08) 6384 5884 and get it right the first time.

What Is a Submersible Bore Pump and Why Deep Bores Need One

A submersible bore pump is a sealed, multistage pump that sits underwater inside your bore or well and pushes groundwater to the surface. Surface pumps pull water up by suction, and physics limits suction to about 7 or 8 metres in real conditions. Submersible bore pumps have no such limit because they push from below, which is why they are the only practical option for the deep bores common across Australia. They run silently underground, never need priming, and the surrounding water cools the motor while it works. In our experience, a correctly sized submersible bore pump paired with a good pump controller will run 10 to 15 years or more before it needs attention. An undersized one can burn out inside two summers. If you are still weighing up pump types, our guide comparing submersible and centrifugal water pumps walks through the differences in plain language.

How to Choose the Right Submersible Bore Pump

After a decade of sizing bore pumps for Australian properties, we can tell you the three numbers that matter. Get these right and almost any pump in this collection will serve you for years.

Bore Depth and Total Dynamic Head

Total dynamic head is the real distance your submersible bore pump has to move water: standing water level, plus drawdown while pumping, plus the lift to your tank or troughs, plus pipe friction losses. The most common sizing mistake is using bore depth alone. A 60 metre bore feeding a header tank 300 metres up a paddock needs far more head than the bore depth suggests. As a rough guide, our SQ series suits bores to around 100 metres of head, the SQE series reaches about 155 metres, and the SP series handles deep bores well beyond 200 metres of head.

Flow Rate and Daily Water Demand

Match flow to demand, not to the biggest number on the box. A household on bore water typically needs 1 to 2 cubic metres per hour. Livestock troughs and garden irrigation sit around 2 to 5. Broadacre irrigation, horticulture and commercial supply run 5 to 14 or more. A submersible bore pump that is too big for the bore yield will pump the bore dry and cycle on and off, which is the fastest way to kill a motor. Pair your pump with a properly sized pressure tank and pressure control components to smooth out demand and protect the motor.

Single Phase, Three Phase or Variable Speed

Single phase 240V submersible bore pumps suit homes, hobby farms and any site on standard power. Three phase 415V models deliver more grunt for large farms, commercial sites and high volume irrigation. If you need constant pressure at the tap, the variable speed SQE range adjusts its own motor speed to hold pressure steady, which household users love. Use the filters above to narrow this collection by phase, voltage, motor power and flow rate, or call us and we will do it for you.

Grundfos Submersible Bore Pumps: SP, SQ and SQE Series

We stock Grundfos exclusively in this collection, and that is a deliberate choice rather than a limitation. Grundfos submersible bore pumps are the benchmark for bore water reliability worldwide, and in Australian conditions, where iron, salinity and fine sand punish cheap pumps, the difference shows up fast. Every unit here carries the full Grundfos manufacturer warranty and ships with complete technical specifications on the product page.

Grundfos SP Series for Deep Bores and Farms

The Grundfos SP series is the 4 inch heavy duty range built for deep bores, farm irrigation, livestock supply and commercial duty. All steel components are stainless, models are available in 304 or 316 grade for saline bores, and the sand tolerant design copes with the sediment loads that are normal in regional groundwater. SP submersible bore pumps in this collection start from around $1,586 and run up to large three phase units for serious irrigation.

Grundfos SQ and SQE Series for Homes and Smaller Bores

The Grundfos SQ and SQE series are compact 3 inch submersible bore pumps ideal for domestic bore water, tank transfer and garden irrigation. Built in dry run protection, soft start and overvoltage protection come standard, which is protection most competitor brands charge extra for. SQ models start from around $948, and the SQE adds variable speed constant pressure for households that want mains-style pressure from bore water.

Built for Western Australia and Regional Bore Conditions

Pumptastic is WA based, and most of the submersible bore pumps we ship go into exactly the conditions we know best: iron rich bores across Perth and the Swan Coastal Plain, saline groundwater through the Wheatbelt and Goldfields, deep sandy bores in the South West, and remote station bores in the Pilbara and Gascoyne where a pump failure means trucking water. That local knowledge changes our recommendations. For salty bores we steer you to 316 stainless steel. For sandy bores we talk shrouds and sand tolerance before flow rates. For off grid stations we spec motors that handle generator power. We ship submersible bore pumps Australia wide to Queensland, New South Wales, Victoria, South Australia and the Northern Territory too, but if your bore is in WA, you are dealing with a supplier on the same groundwater as you, reachable on a local (08) number during business hours.

Why Buy Your Submersible Bore Pump From Pumptastic

Plenty of sites will sell you a bore pump. Very few will stop you buying the wrong one. Before you order, our team will check your bore depth, standing water level, flow requirement and power supply, then confirm the exact model that fits. You get free shipping on orders over $100 via Australia Post, fast dispatch from stock rather than back orders, full manufacturer warranty on every unit, and honest advice that sometimes means recommending a cheaper pump than the one in your cart. With 3,000+ pumps and parts in stock, we can also supply the controllers, cabling components and pressure tanks that turn a pump into a complete bore water system, so you order everything in one place instead of chasing parts from three suppliers.

Frequently Asked Questions

How deep can a submersible bore pump go?

Domestic 3 inch submersible bore pumps like the Grundfos SQ handle bores to roughly 100 metres of head, the SQE reaches about 155 metres, and 4 inch SP models pump from depths well beyond 200 metres. Always size on total dynamic head, not bore depth alone.

What size submersible bore pump do I need for a house?

Most Australian homes on bore water run comfortably on 1 to 2 cubic metres per hour, which is around 16 to 33 litres per minute. A Grundfos SQ 1 or SQ 2 covers the majority of domestic bores. Call us with your bore details and we will confirm the exact model in minutes.

What is the difference between the Grundfos SQ and SQE?

Both are 3 inch submersible bore pumps with the same build quality. The SQE adds variable speed control, so it holds constant water pressure by adjusting motor speed as demand changes. Choose SQE for household constant pressure, SQ for tank filling and irrigation.

Do submersible bore pumps handle sandy or salty bore water?

Grundfos SP and SQ pumps are engineered with sand tolerance suited to Australian groundwater, and both series are available in 316 stainless steel for saline bores. If your bore is known for heavy sand or salt, tell us before ordering and we will recommend the right grade and a shroud if needed.

How long does a submersible bore pump last?

A correctly sized Grundfos submersible bore pump typically runs 10 to 15 years or more in Australian bores. The two biggest killers are rapid cycling from oversizing and dry running from a low yield bore, and both are preventable with correct sizing and protection.

Single phase or three phase, which do I need?

If your property has standard 240V power, single phase suits homes and small farms. Three phase 415V suits large irrigation, commercial sites and bigger motors above about 2.2 kW. Check your switchboard before ordering, or ask your electrician.

Can I install a submersible bore pump myself?

The mechanical installation is straightforward for a capable property owner, but the electrical connection must be done by a licensed electrician in every Australian state. We supply full specifications and wiring details with every pump.

Why is my current bore pump losing pressure?

Falling pressure usually points to worn impellers, a dropping water table, a blocked inlet screen or a failing pressure system. If the pump is over a decade old, replacement is often cheaper than repair. Send us your current model and symptoms and we will give you a straight answer.

Do you ship submersible bore pumps outside Western Australia?

Yes. We ship Australia wide via Australia Post with free shipping on orders over $100, and most in stock pumps dispatch fast. Regional and remote deliveries are our bread and butter.

What if I order the wrong submersible bore pump?

Call us before you order and you will not. Our team specs pumps against your bore depth, flow need and power supply every day. It costs you nothing and it is the reason our warranty claims are rare.
