Our marine pump is a positive displacement pump, which can be widely used in the shipbuilding industry.
Shipbuilding: used as marine loading pump, scavenger pump, marine ballast pump, main engine lubricating oil pump, cargo oil pump, etc.
Tank farm oil delivery, backfilling, loading pump, fuel transfer pump, fuel injection pump, etc. l
Structural features and advantages
Low Noise And Long Life
Low vibration, no direct mechanical wear, low noise and long service life.
Stable Pressure And No Pulsation
Stable conveying pressure and constant flow rate. No pulsation or stirring medium, continuous and smooth supply.
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.
The pump of this structure is a double-suction horizontal installation. 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 (the gap value is determined by the working conditions and the specifications of the pump itself). 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. In addition to transporting good lubricating media, 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)
Performance Range of Our

Medium viscosity: 0.5~100000 mm2/s
Speed: 50~1500 r/min
It should be noted that the performance parameters corresponding to each series are different. When selecting models, please contact us anytime, our professional technician will provide you correspond information.
The import and export direction of the pump is determined by the user. When there is no special requirement for the import and export direction of the pump, our company recommends the horizontal direction, which is left in and right out when viewed from the direction of the motor.
After confirming the model, if you need more detailed drawings and installation dimensions, please contact us and our technical department will answer for it. Besides, if you have any requirements about the specifications of the inlet and outlet flanges of the pump, please also negotiate with us.
