Commercial Pressure Boosting

Most apartment blocks, hotels, offices and schools need a twin-pump variable speed booster set, like the EBARA 2GPE Matrix. Two pumps share the load and back each other up, so the building is never left without water. The 2GPE handles up to 500 l/min and 72 m head. For light commercial and residential buildings, the single-pump EBARA 1GPE Matrix handles up to 250 l/min and 72 m head. We size every commercial set to the building, free of charge.

It depends on the number of flats and floors. This guide is for flats with two bathrooms and a kitchen, using the EBARA 2GPE Matrix:

The codes are 2GPE Matrix pump sizes. The guide assumes a new installation, with the set at ground level near the outlets. If the set will sit in a basement or garage, add one floor. Every building is different, so send us the details and we'll confirm the size.

Duty/standby means one pump (the duty pump) does the work, while a second pump stands ready to take over if the first stops. Duty/assist means that when demand rises beyond what one pump can deliver, the second pump joins in automatically. The EBARA 2GPE Matrix does both. Its pumps also alternate starts, so they wear evenly. That's why it's the standard choice for buildings that can't afford to lose water.

Both use EBARA's stainless steel Matrix multistage pumps with inverter control, holding a constant pressure however demand changes. The difference is how many pumps share the work:

• 1GPE Matrix: one pump, up to 250 l/min and 72 m head. It comes with a potable pressure vessel sized to the pump, and has dry-run, overload and voltage protection. Best for light commercial and residential buildings.
• 2GPE Matrix: two pumps on one base, each with its own inverter, up to 500 l/min and 72 m head. It has duty/assist and built-in standby, and comes factory assembled with manifolds, valves and two vessels. Best for apartment blocks, hotels, offices and schools.

Both run on a 230 V single-phase supply as standard, with 400 V three-phase drives available on request.

Yes. Every booster set is assembled, tested and commissioned by our team before it leaves us. It goes through factory hydraulic, mechanical and electrical tests, the pressure is set, and every function is checked. It arrives set up for your building, ready to connect, with the pressure vessels sized to the pump. On-site commissioning by our engineers is available on request.

A variable speed booster set runs only as hard as the building needs at any moment. Pressure stays steady whether one tap or fifty are open, running costs drop, and the pumps last longer because they aren't constantly switching on and off at full power. In buildings with uneven demand, like hotels at 7am, the energy saving is significant.

To size a commercial system properly, we need:

• The number of flats or units, and the number of floors.
• The number and type of outlets (showers, WCs, basins, kitchens).
• Where the set will sit: ground floor, basement or garage.
• The size and location of the break tank.
• The power supply available (single- or three-phase).

Drawings help if you have them. See Before you call us, or send us the details.

We install domestic booster pumps and commercial booster sets across Dublin city and county. Borehole pumps, drainage and sewage pumps, and water treatment systems are supplied for your installer to fit. We match every part to the job, and we're happy to talk your plumber or installer through the setup. Outside Dublin, we deliver nationwide (next working day on in-stock items).
