GRAF | PRESS guide

Commercial pressure booster systems

Package duplex or multi-pump boosters around building pressure, tank boosting and reuse duty.

In short

Commercial pressure booster systems raise water to the required discharge pressure for buildings, tanks and reuse outlets. GRAF | PRESS provides packaged pump sets with pressure control and protection around a confirmed project duty. GRAF | LIFT, PRESS, REUSE and CARE are being rolled out Australia-wide excluding Victoria. Project delivery, commissioning and field attendance are confirmed against location and scope.

How it works

Supply or tank feed enters a GRAF | PRESS package, then delivers controlled pressure to building or reuse outlets.

What to do next

  1. 01

    Confirm flow and pressure

    Required discharge pressure and design flow for the outlets served.

  2. 02

    Confirm supply arrangement

    Mains, tank, rainwater or reuse feed, and whether a break tank is required.

  3. 03

    Select PRESS package path

    Duplex, multi-pump, transfer or break-tank booster around the duty.

Where commercial boosters are used

Commercial building water pressure, tank boosting, rainwater delivery and suitable reuse pressure systems are common GRAF | PRESS applications.

The initial range is based on pre-confirmed package configurations rather than unlimited bespoke pump engineering. Share duty notes for selection.

GRAF tank supply used with commercial pressure booster packages
Tank and reuse feeds often pair with PRESS packages.

What to send for sizing

Required flow, required pressure, supply arrangement, fluid type, power supply, control and protection needs, vessel or break-tank requirements, and drawings where available.

Do not publish or rely on invented flow, kW or pressure envelopes. Final selection is project confirmed.

Commercial site using packaged pressure and transfer systems
Building and site water services drive package selection.

Frequently asked questions

What is a commercial pressure booster system?+
A packaged pump set that raises water pressure for building services, tank boosting, rainwater or suitable reuse delivery. GRAF | PRESS provides duplex and multi-pump packages around a confirmed duty.
What information is needed to select a booster?+
Required flow, discharge pressure, supply arrangement, fluid type, power supply, control and protection requirements, and whether a break tank or hydraulic separation is needed.
Are flow and pressure envelopes published?+
Do not rely on invented flow, kW or pressure limits. Final package selection is confirmed against the project duty. Share duty notes for a GRAF | PRESS quote.
Is GRAF | PRESS available nationally?+
The active rollout is Australia-wide excluding Victoria. Delivery and field attendance are confirmed against project location and scope.
When should I choose multi-pump instead of duplex?+
Higher-demand building or reuse systems often need multi-pump sequencing. Duplex packages suit many two-pump building and tank boosting duties. Confirm with project flow and redundancy needs.
