Process diaphragm pumps as high pressure fuel injection pumps …
LEWA offers robust and safe diaphragm pumps for use in fuel gas supply systems on ships – they are particularly suitable for LPG, ammonia or methanol. Different sizes enable optimum adaptation to the respective engine size. The LEWA triplex diaphragm pump offers many advantages as a fuel pump for alternative fuels in marine engines:
Diaphragm Pumps - Marine Technic
Double diaphragm pumps are operated by compressed air or any non-flammable compressed gas. The pumping stroke begins as air is delivered by the air distribution system, putting pressure on one diaphragm and then the opposite diaphragm.

ARO diaphragm pumps are used in a variety of de-watering, fuel transfer, and bulk transfer of all types of liquids applications during the build process and the normal operating life of many maritime vessels. These industrial-grade pumps provide high performance and stall-free reliability. They are available with flow rates up to 237 GPM (897.
Air-Operated Double Diaphragm Pumps for the Marine Industry - Graco …
In vessels throughout the world, this highly reliable pump can be found emptying oil or chemical tanks, and can be used to empty a tank when chemical products are spilled. This pump can replace a fixed electric pump in case of failure or when a pump is needed that is better in priming for a longer distance.
Types of Pumps in Ship’s Engine Rooms – Maritime Education
Diaphragm Pumps: Use a diaphragm to move fluid, suitable for abrasive or corrosive fluids in bilge systems or smaller hydraulic applications. Plunger Pumps: Similar to piston pumps but with a plunger mechanism, these are suitable for very high-pressure applications and are often used in hydraulic systems.
Choosing a Pump - West Marine
2022年11月3日 · Diaphragm pumps use a variable volume pump chamber and check valves to move fluid. As the diaphragm rises, liquid is pulled into the pump chamber while the outlet valve is pulled close. When the diaphragm is lowered, liquid is forced out the outlet valve while the intake valve is pressed shut.
What is Positive Displacement pump used on ships?
2023年9月1日 · “A diaphragm pump is a positive displacement pump that uses a combination of reciprocating action on a rubber, thermoplastic, or Teflon diaphragm, with suitable valves fitted on both the suction and delivery sides.
Diaphragm Pumps: Advanced Technology and Applications - EDDY Pump
2024年8月30日 · At the core of a diaphragm pump’s operation is a flexible diaphragm that moves fluid by creating a variable-volume chamber. This pump chamber expands and contracts as the diaphragm moves, allowing fluid to be drawn in during the intake stroke and expelled during the discharge stroke.
Displacement, Axial flow and Centrifugal Pumps for Ship Use
There are three main classes of pump in marine use: displacement, axial flow and centrifugal. A number of different arrangements are possible for displacement and centrifugal pumps to meet particular system characteristics. Positive displacement pumps are pumps in which one or two chambers are filled and emptied.
