Hydrophore Systems with fresh water and sea water - Gashandling and self priming capabilities are requested

On all ships a  coninuous water supply is essential. The solution on board are hydrophore systems ( pressurized tanks ).

To assure a continuous process a variety of technical features are required for the pump technology used in these hydrophore systems.


Producer: SERO

Pump SOH 223 in cast iron
Medium Water
Flowrate 4 m³/h
Pressure 4-5 bar
Temperature ambient
Viscosity 1 cst
Rational speed 1450 rpm or 1750 rpm depending on the ships frequency


The task of the pump is to prime water from a deeper seated container and transports it with a relatively high pressure and low flow into the hydrophore system. The flow must not be interrupted. In a possible event of a drain in the suction piping, the pump has to vent the piping self-actuating.


A pump that my handle gas and is self-priming has to be used. Due to its self-priming capabilities and the steep performance curve, a Side Channel Pump is the best solution for this task. In many ships Side Channel Pumps are used to guarantee a continuous water supply.
