High Efficiency Pump

the mechanical efficiency of conveying is the highest, and the energy-saving effect is good


Marine twin-screw pump is a type of positive displacement pump. It has the advantages of smooth conveying, no pulsation, no stirring, low vibration, low noise, and strong self-priming performance. With the correct selection of materials and structures, it can convey lubricating or non-lubricating, clean or low-viscosity or low-viscosity containing solid particles. Various media with high viscosity, with or without corrosiveness. Shaft seals are available in various forms, with long service life, less leakage and a wide range of applications. It also has vertical and horizontal differences.

How to choose the type of pump for a ship?

The functioning of a ship is supported by various types of fluids that flow through the different machinery and systems within the ship for cooling, heating, lubrication and as fuel. These fluids are circulated through different types of pumps which can be independently driven by the ship’s power supply or connected to the machinery itself. All systems on board require proper operation and compatible pumps and pumping systems in order for the ship to sail smoothly.

Which type of pump to choose for a boat depends on the characteristics of the fluid to be pumped or circulated. These include properties such as viscosity, density, surface tension, and compressibility, and also need to be based on the characteristics of the pumping system, such as the demand rate of the fluid, the pressure head at which the fluid is pumped, the temperature encountered in the system, and the pressure at which the fluid is handled in the system, etc. .
