Marine screw pumps:

overview

Marine screw pumps are driven by marine motor,used on the boat to deliver such medium as sewage, fuel and lubricating oil.

Marine single-screw pump

Marine single-screw pump is horizontal structure, driven by marine motor. It is used on the boat to deliver such medium as sewage, fuel and lubricating oil.

Installed with trolley, electrical startup box, cables, fast connector and suction/drainage hose, this pump may used as movable pump.

Max. Capacity	330m3/h
Max. Head	2.4MPa
Suction Lift	Up to 8.5m
Max. Solids	50mmφ
Max. Viscosity	200,000ps

Marine Twin Screw Pump

Marine twin screw pump are horizontal twin screw pumps with external bearing. In this design, the bearings do not come into contact with the media.

A further advantage of this design is that it can pump fluids at higher temperature up to Up to 300.

Capacity	Up to 2700 m3/h
Differential Pressure	Up to 50bar
Viscosity	0.5 to 200,000cSt
Max. Speed	3600rpm
Temperature	Up to 300

Three Screw Pump

Three screw pumps are commonly used for machinery lubrication; hydraulic elevators; fuel oil transport and burner service; powering hydraulic machinery; in refinery processes for high temperature viscous products such as asphalt, vacuum tower bottoms and residual fuel oils; in crude oil pipeline service and gathering, boosting and loading barges and ships. They are common in engine rooms on most of the world's commercial marine vessels and many combat ships.

Designs are available in sealless configurations such as magnetic drives and canned arrangements.
