Grundfos Multi Booster Pumps

Grundfos Hydro Booster Set Australia: Hydro Multi-E and MPC-E Pressure Systems

A Grundfos hydro booster set is the fastest way to fix low water pressure in a commercial building, farm, mine camp or apartment block. Instead of piecing together pumps, valves, tanks and controls yourself, you get a complete pressure boosting system that arrives factory-built, factory-tested and ready to connect. Pumptastic stocks the full Grundfos Hydro Multi-E and Hydro MPC-E range right here in Western Australia, ships Australia wide, and backs every unit with real pump engineers you can call on (08) 6384 5884. Every model on this page is listed with live Australian pricing, and selected sets are on sale now.

What Is a Grundfos Hydro Booster Set and Who Needs One

A Grundfos hydro booster set combines two or more CR series multistage centrifugal pumps on a single stainless steel manifold, complete with isolation valves, non-return valves, a pressure transmitter, gauges and a diaphragm pressure tank. The pumps run in parallel and share the load. When demand rises at morning peak, extra pumps ramp up. When the building goes quiet at 3am, they wind back down. Your taps, showers, irrigation lines and process equipment see one thing only: constant, stable pressure.

That constant pressure is why these systems are specified so often by Australian consulting engineers. Hospitals cannot tolerate pressure drops in a ward. High-rise apartments in Perth, Sydney and Melbourne need reliable pressure on the top floor at dinner time. Broadacre farms running pivot or lateral irrigation need consistent flow across long mainlines. Mine camps in the Pilbara and Goldfields need water infrastructure that keeps working without a technician on site. A Grundfos hydro booster set handles all of these because redundancy is built into the design. If one pump stops, the next pump takes over automatically, so a single fault never becomes a water outage.

If you are currently running one large fixed-speed pump, the difference is significant. A single pump either runs flat out or not at all, which wastes power and hammers your pipework with pressure spikes. A variable speed booster set only produces the pressure and flow the system actually needs, second by second. Most commercial sites see the power savings alone repay the price difference within a few years of duty.

Hydro Multi-E vs Hydro MPC-E: Choosing the Right Booster Set

Pumptastic carries both families, and the choice comes down to control style and project scale.

The Hydro Multi-E is the plug-and-pump option. There is no separate control cabinet because the intelligence lives inside the pumps themselves. Each CRE pump carries a Grundfos IE5 permanent magnet motor with an integrated frequency drive, and the pumps talk to each other directly. Any pump can act as the master, which means full redundancy even at the control level. Commissioning takes minutes through the display on the lead pump, and Grundfos GO Remote lets your contractor monitor and adjust the system from a phone over Bluetooth. For hotels, schools, aged care facilities, retail centres and irrigation duties, the Hydro Multi-E 2 (two pumps) or Hydro Multi-E 3 (three pumps) covers flows from small boutique sites up to 70 cubic metres per hour and beyond.

The Hydro MPC-E is the premium tier of the Grundfos hydro booster range, built around CRE or CRNE pumps with a dedicated CU 352 control panel. This is the set consulting engineers specify when a project needs deep building management integration, cascade control of up to six pumps, or advanced functions like pipe fill mode, redundancy sensors and proportional pressure control. An optional CIM fieldbus module connects the system straight into Modbus, BACnet or Profinet, which makes the MPC-E the default choice for smart buildings, water authorities and industrial process water. On this page you will find MPC-E 2, MPC-E 3 and MPC-E 4 configurations with flows past 340 cubic metres per hour.

Not sure which family fits your duty point? Send us your peak flow, required discharge pressure and suction conditions through our contact page and our engineers will return a sized model number, usually the same business day. If your project actually needs individual multistage pumps rather than a packaged set, our Grundfos vertical multistage pump range uses the same CR hydraulics, and our Grundfos pressure pumps cover smaller domestic and light commercial duties.

Built for Western Australia: Perth Stock and Regional Delivery

Pumptastic dispatches every Grundfos hydro booster set from our Western Australia warehouse, which matters more than most buyers realise. Eastern states suppliers freight WA orders across the Nullarbor, adding days and cost. We work the other way around. Perth metro, Mandurah, Bunbury and the South West get fast dispatch, and we ship daily to regional WA including Geraldton, Kalgoorlie, Albany, Karratha, Port Hedland and Broome. Mining contractors, pastoral stations and regional water utilities across WA deal with us precisely because the stock, the engineers and the spare parts are all in the same state.

That local depth extends past the sale. We keep critical Grundfos spares on hand, including CRE shaft seals, pressure transmitters and replacement diaphragm tanks, so a planned shutdown in the Pilbara is not held hostage to a back-order from Europe. WA's water conditions also shape our advice. Bore-fed systems in the Wheatbelt, scheme water boosting in Perth suburbs and high-temperature duties in the North West each pull different models from the range, and we size for your real conditions, not a generic catalogue curve. If your supply comes from a bore, pair your booster set with one of our submersible bore pumps and we will match the two hydraulically.

And WA is only our home base. Free shipping applies Australia wide on orders over $100, so builders in Brisbane, irrigators in the Riverina and facility managers in Melbourne buy from this page every week at the same trade-direct pricing.

The Engineering That Cuts Your Power Bill

Every set we sell is a genuine Grundfos-built unit, never a re-badged import. The motors are IE5 permanent magnet synchronous units, the highest efficiency class currently available and well above the minimums that modern Australian commercial specifications call for. That efficiency is not a brochure line. Pressure boosting runs around the clock, so a few percentage points of motor efficiency compound into thousands of dollars over the life of the system, and it supports Green Star and NABERS targets on rated buildings.

The wetted materials matter just as much. Manifolds are AISI 316L stainless steel, wetted pump internals are stainless, and the materials meet AS/NZS 4020 for drinking water along with WRAS and ACS approvals where applicable. The same booster set that pressurises a distribution centre can lift potable mains supply into an apartment tower. Each system ships with its diaphragm tank, gauges and transmitter pre-piped to the base frame, IP54-rated motors, and a maximum working pressure of 10 or 16 bar depending on model. Need extra storage or a larger tank on the discharge side? Our pressure tanks and pump controllers bolt straight into the same installation.

Frequently Asked Questions

What is a Grundfos hydro booster set?

It is a complete packaged pressure boosting system built by Grundfos. Two or more multistage pumps sit on one base frame with a stainless manifold, valves, pressure tank, transmitter and controls already fitted and tested. You connect suction, discharge and power, then commission it in minutes.

Which Grundfos hydro booster set is best for a commercial building?

For most hotels, offices, schools and aged care sites, the Hydro Multi-E 2 or Multi-E 3 is the right fit because it is compact, redundant and simple to commission. For high-rise towers, hospitals and projects needing BMS integration, specify the Hydro MPC-E with the CU 352 controller.

How much does a Grundfos hydro booster set cost in Australia?

Pricing depends on the pump curve and configuration. Sets on this page run from smaller Multi-E systems through to large MPC-E 3 units above $100,000. Every price is shown live in Australian dollars, and selected models are on sale. Call us for project or bulk pricing.

Do you deliver booster sets to regional Western Australia?

Yes. We dispatch from our WA warehouse to Perth metro and regional centres including Geraldton, Kalgoorlie, Albany, Karratha, Port Hedland and Broome, plus every other Australian state. Shipping is free on orders over $100.

Can a Grundfos hydro booster set supply drinking water?

Yes. The wetted materials, including the AISI 316L stainless manifold, meet AS/NZS 4020 drinking water requirements, with WRAS and ACS approvals where applicable, so the sets suit potable boosting in apartments, hospitals and community water schemes.

What is the difference between Hydro Multi-E and Hydro MPC-E?

The Multi-E has no separate control cabinet; the pumps control themselves and each other. The MPC-E adds a dedicated CU 352 control panel with advanced cascade control and fieldbus options for Modbus, BACnet and Profinet. Multi-E suits most commercial duties; MPC-E suits complex and critical ones.

Can I run a Grundfos booster set on single phase power?

Smaller Hydro Multi-E models are available in 200 to 240V single phase. Larger sets require 380 to 415V three phase. Check the specifications on each listing or call our engineers to match a model to your switchboard.

How do I size a booster set for my site?

Send us your peak flow in litres per second or cubic metres per hour, the discharge pressure you need, and your suction conditions. Our Perth-based engineers will return a sized model and quote, usually the same business day. A hydraulic schedule or building drawing works too.

Is the Grundfos warranty valid when I buy online from Pumptastic?

Yes. Pumptastic is an authorised Grundfos supplier in Australia, so the full manufacturer's warranty applies to every booster set sold on this page, and we manage any claim process for you.

Do you stock spare parts for these booster sets?

Yes. We hold critical spares including CRE shaft seals, pressure transmitters and diaphragm tanks in our WA warehouse, so maintenance and planned shutdowns are never waiting on overseas freight.
