Marine High Pressure Pumps, are commonly used marine pumps, which on ships are for high-pressure water mist fire fighting and seawater desalination. For fixed water-based fire fighting system pump is EMH vertical multistage centrifugal pump, for hyper mist fire fighting system pump is PAH high pressure pumpand for reverse osmosis aeawater sesalination aystem pump is APP high pressure desalination pump.

PAH high pressure pump is designed and manufactured based on the principle of axial piston pump, with light weight and compact structure. At the same time, water is used as the lubricating medium of the friction parts, so there is no need to add lubricating oil. This series of pumps is a fixed displacement pump, the displacement is proportional to the shaft speed and the angle of the swash plate. Max. pressure will be 160bar.

EMH marine vertical multistage centrifugal pump’s structure is simple and compact, and the size and weight are much smaller than reciprocating pumps with the same capacity, and the cost is also much lower. The flow is continuous, stable and easy to adjust, and the applicable of flow range is large, generally 1~200m³/h used on ships.

APP high pressure desalination pump is designed to transport high-pressure, low-viscosity corrosive fluids, such as seawater in seawater reverse osmosis system. APP pump is also based on the principle of axial piston pump, which uses the volume change caused by the reciprocating movement of the parallel plunger to the transmission shaft in the plunger hole to work, and uses the fluid itself to lubricate the moving parts of the pump. This series of pumps has its own integrated check valve, which allows fluid to flow from the inlet to the outlet through the check valve when the pump is stopped.
