Break tank booster systems

Boost from stored supply or an approved hydraulic separation arrangement when direct mains boosting is not the right path.

In short

A break tank booster system draws from stored supply or an approved separation arrangement, then packages pumps and pressure control to the required discharge pressure. GRAF | PRESS Break-Tank Booster System is the commercial pathway for that 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

Stored supply feeds the PRESS break-tank booster package, which delivers controlled discharge pressure.

What to do next

  1. 01

    Confirm why a break tank is needed

    Stored supply, separation requirements or controlled feed before boosting.

  2. 02

    Define flow and pressure

    Design flow, discharge pressure and protection requirements.

  3. 03

    Quote the PRESS break-tank path

    Include tank arrangement notes and drawings with the request.

When break-tank boosting is specified

Projects that cannot or should not boost directly from the upstream source often use stored supply or an approved hydraulic separation arrangement before the booster set.

Rainwater and reuse systems may also feed a break-tank style arrangement depending on site rules and hydraulic design.

GRAF storage used as break-tank supply for commercial boosting
GRAF storage can form part of the break-tank arrangement where suitable.

What the package focuses on

Pressure control, pump protection, sequencing and the relationship between tank levels and booster starts are the core selection topics.

Final flow, motor and pressure envelopes are project confirmed. Do not invent published limits for catalogue pages or guides.

Frequently asked questions

What is a break tank booster system?+
A packaged pressure-boosting arrangement where water is drawn from stored supply or an approved hydraulic separation arrangement, then boosted to the required discharge pressure.
When is a break tank required?+
When the project needs stored supply, hydraulic separation from the upstream source, or a controlled feed arrangement before boosting. Confirm authority and hydraulic requirements for the site.
Does GRAF supply the tank and the booster?+
GRAF | PRESS Break-Tank Booster System is the packaged boosting path. GRAF storage products can form part of the arrangement where suitable. Selection depends on project scope.
What duty data is required?+
Required flow and discharge pressure, tank or supply arrangement, fluid type, power supply, control and protection requirements, and drawings where available.
Are published pressure limits available?+
Do not rely on invented pressure or flow envelopes. Final package selection is confirmed against the project duty through GRAF Australia.
