Due to the tight impeller clearance with the pump volute, which is why they are generally used with water and other low viscosity fluids. This combined with their high pressure range, makes multistage water pumps popular in applications:
Boiler feed
Reverse osmosis
Water supply boosting
Irrigation
Fire fighting
Heating/cooling conditioning

Key points for operating booster pumps

1. Avoid dry starting: Priming is done before pumping begins to prevent a dry start, possibly leading to a pump breakdown.
2. Avoid back-pressure: Pay close attention to installing a bypass filling line to prevent back pressure in the discharge line, which could obstruct the priming procedure. Airflow via the suction line is blocked by the back-pressure that builds up in the discharge line due to air bubble accumulation.
