A hydrophore can refer to: Hydrophore (sampling), a scientific instrument for obtaining samples of water from a body of water from any desired depth; Hydrophore (system) [nl]. This new electronically controlled hydrophore system incorporates state of the art frequency drives, pumps and control technology. Why hydrophore system is mandatory onboard? Hope you know that the demand of freshwater is different in different parts of the ship ranging from minimum.

At first fix this problem temporarily by crack open the vent valve and letting some air go. Once its at 4. Being under charged is one of the most common problem of hydrophore. Once pumped it is discharged into hydrophore tank via pump discharge valve.

Home Systems Hydrophore Systems. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use. Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. When the pressure inside the hydrophore reduced to a certain value the pump start. Make sure that the pump cutoff at 5. Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank.

Once the pressure reach 4. But for long term solution you have to apply soap solution on all joints and key leak point. When a high flow firewater consumer starts before the fire water pumps, water is drained from the highest points of the ring main. Open your air supply valve and pressurize tank up till 5.

It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump.


V sterilizer before consumption. V sterilizer and then to accommodation. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water.


In small ships or industries with small hydrophore the system may be required to cut in at 2. There is a continues use of water on ship from drinking to sanitary purposes. The Firenor hydrophore system is a safety system designed to prevent pressure surges in the firewater distribution piping that occur when a deluge system or any other water consuming systems release water before fire water pumps are up and running. The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care.

You can consider its working similar to that of below in your bathroom sink. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass. Now the pump will cut-in when the pressure reach 4. This is quite rare but possible problem you may face with hydrophore system. This drain results in a vacuum in the upper levels of the ring main.

The situation can be found with no water supply at the accommodation top. Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps.

Hydrophore Systems | Firenor – Active Firefighting Systems

All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements. So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh? Once water is pumped in the hydrophore tank to a certain limit; Low pressure compressed air is then introduced from the top at a pressure of 4.

The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Then when the air pressure is 4. This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself.


This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. Furthermore, the entire hydrophhore also includes all valves and instrumentation necessary for standard operation, maintenance, and testing.

Make sure to watch that the pump cut-in and cutoff at the desired pressure next time.

Close the vent and open the low pressure air supply valve. This means there hyddophore a leak in air supply line or the valve itself slowly filling tank with more and more air. Avoid overcharging, otherwise air will came out of the taps with water.

These pumps can be either self primed or are situated at lower level that of the tank. Have you ever imagined how fresh water is transported to all decks and places on ship? Documentation normally includes the following: Leave a Comment Cancel reply Your email address will not be published. Gravity works as a source to supply water at desired pressure at all points. This pressurizes the pipes and practically hydrophode the risk of a pressure surge by preventing the vacuum from ever forming.

Once leak detected stop and Ysstem the system and rectify the fault.

Marine Pressure Hydrophore Tank

Your email address will not be published. In case of drinking fresh water system the output from hydrophore tank go through U. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve.

On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.
