Why Australia's Builders, Engineers and Property Managers Trust Hydro Multi-E

The Grundfos Hydro Multi-E is a complete, plug-and-pump pressure boosting system built around two or three parallel-connected CRE multistage centrifugal pumps. Each pump is driven by a Grundfos IE5 permanent-magnet (PM) synchronous motor with an integrated frequency converter, delivering the highest motor efficiency class currently available well above the IE3 minimum that Australian commercial mechanical specifications now demand. That means lower running costs, reduced carbon footprint, and full compliance with modern Green Star and NABERS-rated builds across Sydney, Melbourne, Brisbane, Perth and Adelaide.

Constant pressure is held by a built-in PI controller, so flow can swing wildly between morning peak and 3am idle without the discharge pressure drifting. Dual-master redundancy is standard on every set if pump one drops out, pump two ramps up automatically, which is the kind of reliability you need behind a hospital ward, a high-rise riser, or a piggery's wash-down line.

What Makes the Hydro Multi-E Different, The Engineering Inside

Every Hydro Multi-E sold by Pumptastic is the genuine Bjerringbro-built unit, not a re-badged import. The manifolds are AISI 316L stainless steel, pump housings are cast iron with AISI 304 stainless wetted parts, and the 24-litre PN16 diaphragm tank, isolation valves, non-return valves, pressure gauges and pressure transmitter are pre-piped to the base frame. Motors are IP54-rated, the system handles clean water from 5 to 60 °C, and depending on the model the maximum operating pressure runs to 10 or 16 bar.

Drinking-water approvals matter for potable applications, and the wetted materials meet AS/NZS 4020, WRAS and ACS where applicable so the same set that boosts a Coles distribution centre can lift mains pressure into a Brisbane apartment tower without compromising potability.

Commissioning is genuinely fast. The graphical control display on the lead pump walks you through start-up in minutes, and Grundfos GO Remote lets your contractor pair via Bluetooth from a phone. For BMS or SCADA integration on a smart building, an optional CIM fieldbus module plugs straight in for Modbus, BACnet or Profinet.

The Right Booster Set for Every Australian Application

Pumptastic carries the full flow envelope. The Hydro Multi-E 2 x CRE 3 handles flows up to 10.8 m³/h and suits boutique hotels or small retail centres. Step up through the Hydro Multi-E 2 x CRE 5, CRE 10, CRE 15 and CRE 20, and you cover everything from district heating loops to mining camp accommodation blocks, with flows reaching 70 m³/h per duty point. Three-pump Hydro Multi-E 3 systems deliver heavier flows and an additional layer of redundancy for hospitals, water authorities and food-grade facilities see the three-pump CRE 10, CRE 15 and CRE 20 sets currently listed on this page, or contact our team for a tailored quote.

Common Australian use cases we supply daily include commercial water pressure boosting for hotels, offices and aged-care facilities; district heating and cooling for university campuses; industrial process water and clean transfer; community water supply through small water utilities; rotor, spray, pivot and lateral irrigation for broadacre farms; livestock and wildlife watering; solar boosting for off-grid stations; fertigation and chemigation in horticulture; and frost protection across orchards in the Goulburn Valley, Yarra Valley, Adelaide Hills and Tasmania.
