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.

Cover all sections of piping with a single system. Documentation normally includes the following:. Your email address will wystem be published. Make sure that the pump cutoff at 5. Then when the air pressure is 4. Water is stored in the hydrophore tanks situated in the engine room; It is then pressurized using compressed air from air bottle via pressure reducing valve.

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. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room.

Marine Pressure Hydrophore Tank

Once leak detected stop and DE-pressurize the system and rectify the fault. But for long term solution you have to apply soap solution on all joints and key leak point. These pumps are controlled by the pressure switches installed on hydrophore tanks. Avoid overcharging, otherwise air will came out of the taps with water. The engineering department produces documentation relevant to all phases of the project. In small ships or industries with small hydrophore the system may be required to cut in at hydrophors.

There is a continues use of water on ship from sywtem to sanitary purposes.

What is a Hydrophore System ? | Marine Notes

An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top. Once its at 4. Once the pressure reach 4. Home Systems Hydrophore Systems. Syste, output from the domestic fresh water hydrophore tank is connected to lines for domestic use, to fuel oil purifier and expansion tank; while the output of drinking fresh water tank to the U.


This is quite rare but possible problem you may face with hydrophore system. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use. Make sure to watch that the pump cut-in and cutoff hyfrophore the desired pressure next time.

These pumps can be either self primed or are situated at lower level that of the tank. The release and reset mechanisms for all parts of the hydrophore system are fully automatic. V sterilizer and then to accommodation.


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. This drain results in a vacuum in the upper levels of the ring main. 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. This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself.

Hydrophore – Wikipedia

To prevent this dangerous situation, the hydrophore system will discharge water into the firewater ring main from the hydrophore water vessel as soon as the pressure control valve senses a pressure drop. Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure.


Close the vent and open the low pressure air supply valve. The water vessel for the Firenor hydrophore system has a standard water capacity that is capable of functioning for up to 30 seconds, long enough to prevent pressure surges in standard fire protection systems.

At first fix this problem temporarily by crack open the vent valve and letting some air go.

Quick Charge the hydrophore tank up to it reach 4. Being under charged is one of jydrophore most common problem of hydrophore. The situation can be found with no water supply at the accommodation top.

This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming. Hydropbore the pressure inside the hydrophore reduced to a certain value the pump start.

Now transfer the system on auto. Make sure the water is always visible through the gauge glass throught the operation. When a high flow firewater consumer starts before the fire water pumps, water is drained from the hudrophore points of the ring main. Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps.

Gravity works as a source to supply water at desired pressure at all points.

It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water.
