In short

Commercial water transfer packages move volume between storage or process points under level or pressure control. GRAF | PRESS Water Transfer System is the packaged pathway for that duty beside duplex and multi-pump boosters. 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

Source tank or process feed enters a PRESS transfer package, then moves water to the destination under control.

What to do next

  1. 01

    Map source and destination

    Tank levels, process points and whether pressure at the destination matters.

  2. 02

    Confirm flow and head

    Required transfer rate plus static and friction losses on the route.

  3. 03

    Select transfer or booster path

    Use Water Transfer when moving volume; use a booster when outlets need pressure.

Where transfer packages are used

Tank-to-tank movement, intermediate process transfer, rainwater or treated-water feed to downstream packages, and sites that need controlled emptying or topping of storage.

If the destination needs building-style outlet pressure, a booster or break-tank booster path may be the better GRAF | PRESS selection.

GRAF tanks used with commercial water transfer pump packages
Transfer packages often sit between GRAF storage assets.

What to include in a quote

Source and destination arrangement, required flow, head information, fluid type, level or pressure control preference, power supply, alarms and drawings.

Duty envelopes stay project confirmed. Do not invent published flow or kW limits for selection.

GRAF packaged systems for commercial water transfer
PRESS transfer is selected around confirmed site duty.

Compare options

Pick transfer when the job is moving volume; pick boost when outlets need pressure.

Frequently asked questions

What is a commercial water transfer system?+
A packaged pump set that moves water between tanks, processes or intermediate storage under level or pressure control, without necessarily providing building-pressure boosting.
How does transfer differ from a booster?+
Boosters are selected primarily for discharge pressure at outlets. Transfer packages focus on moving volume between locations under level or pressure control. Some sites need both.
What duty inputs are required?+
Source and destination arrangement, required flow, static and friction head, fluid type, control method, power supply and drawings where available.
Can transfer packages serve reuse systems?+
Yes. GRAF | REUSE often pairs storage with a GRAF | PRESS transfer or booster package depending on the end-use pressure requirement.
Is GRAF | PRESS transfer available in Victoria?+
Commercial Systems rollout is Australia-wide excluding Victoria. Confirm delivery against project location and scope.
