marine screw pump

Marine Screw Pump

  • Energy Saving
  • High Efficiency
  • Environmental Protection

The marine screw pump is a type of positive displacement pump, used as marine loading pump, ship bottom sweeping and sewage treatment, main engine lubricating pump, fuel oil pump.

Stable Pressure And No Pulsation

Stable conveying pressure and constant flow rate. No pulsation or stirring medium, continuous and smooth supply.

Low noise and long life

Low vibration, no direct mechanical wear, low noise and long service life.

Self-priming

Excellent self-priming performance. Even if the conveyed medium has a high viscosity.

Wide Range Viscosity And Property

Convey extremely high-viscosity chemical materials and transport medium in high temperature, corrosion, etc.

Structure Features of Marine Screw Pump

This marine screw pump is a double-suction structure of a twin-screw pump, and the spiral surface adopts an advanced Ω-shaped symmetrical form;

Through the bearing positioning, the two screws do not contact each other in the bushing, and a constant gap is maintained between the tooth sides. There is also a constant gap between the circle and the inner surface of the bushing. The transmission of the two screws is completed by synchronous gears. This structure can also transport a large amount of non-lubricating media and media of various viscosities. Since the core working parts of the screw sleeve do not touch each other, there is no danger even if it runs dry for a short time (3~5min). Therefore, it is widely used.

The pump of this structure can realize forward and reverse operation (It is a unique structure designed by our company, please request it in the contract if you need this function)

Application

Tank farm oil delivery, backfilling, loading pump, fuel transfer pump, fuel injection pump, etc.
