High-pressure booster pumps

What a high-pressure booster pump does

A booster pump takes in water with too little pressure and raises it to the pressure the application needs, increasing pressure without starving flow. In a home, a small water pressure booster fixes low plumbing pressure so a shower or tap runs properly, or helps fill a header tank.

On a mine site or in an industrial plant, the job is bigger: delivering process water, wash-down water or fire water at a set pressure, often over long pipe runs or significant elevation, and holding steady pressure as demand changes through the day.

Most pressure booster pumps are centrifugal. Water enters at the inlet, the motor drives the impeller, and the water leaves the outlet at a higher pressure. Where one impeller cannot produce enough head, a multistage booster pump stacks several impellers in series, with each stage adding pressure. Vertical multistage pumps are the workhorse for high-pressure duties at moderate flow, which is why they sit at the centre of most of the industrial booster pump stations we build.

Packaged booster pump stations

A booster pump alone is rarely the whole answer. The station around it decides whether the system holds pressure steadily or hunts and hammers the line: the manifolds, isolation and check valves, suction filtration, pressure tank, instrumentation, switchboard and controls.

We design the station as one system, size the pressure tank to limit pump cycling, and protect the suction side so the pumps are never starved. We build and test stations in our workshop, then deliver them as a skid, a pump room fit-out, or a complete modular building.

Fixed speed or variable speed booster pumps

Ordinary booster pumps run at a constant speed and start and stop on a pressure switch. That suits a steady demand. When demand shifts through the day, a variable speed drive (VSD) adjusts motor speed to match it, maintaining steady outlet pressure while using less energy than a fixed-speed pump running against a throttled valve. The result is a more efficient system and better energy efficiency over the station's life.

Multi-pump stations add duty, assist and standby control. Pumps stage on and off to follow demand and share running hours, and a standby pump takes over if a duty pump faults, so supply continues without anyone on site having to intervene.

Factory Acceptance Testing before it reaches site

We complete a Factory Acceptance Test (FAT) on the entire station in our workshop before installation. The pumps, pipework, valves and controls arrive already proven, so commissioning on site starts from a known baseline instead of debugging the system in place on an operating site. The same process applies across our full range of mining pumps.
