Marine Double Screw Pump

Marine Double Screw Pump

Introduction:

Marine Double Screw Pump also named Marine Twin Screw Pump.This kind of pump adopt double-suction structure, both ends of screw are in the same of pressure cavity, axial force can be balanced automatically. The bearing of both ends adopt external installing, and being lubricated alone by using lubricate, so it won't be influenced by the medium. A couple of synchronous gears are used to drive the screws, so the screw surface can't touch at all, and there is a tiny clearance between the two screws. The impinty in the medium can not fray the screw surface directly ( except scour). Except some less discharge pumps ( below the 2w.w 4.0 )generally, internal safety valve will be installed on the pump body, when the discharge pressure is over the rated they would protect the function.there are two entrance - exit directions, one is horizontally enter and horizontally exit; the other is horizontally enter and vertically upwards exit; the user can choose according to their own demands.

Performance Scope

1. The highest pressure 4.0MPa

2. Capacity range 1~1000 m³/h

3. Temperature range -20~120℃

4. The viscosity of the medium 1~3000 mm²/s when lower the speed of the rotation it can be up to 10⁶mm²/s

Applications:

1.Oil field: Used as the multi-phase mixed transporting pump and crude oil transporting pump.

2.Ship building: Using as marine loading pump, ballast pump and sewage treatment pump,main machine lubricating pump and fuel oil pump.

3.Petrochemical industry: Using as loading and transporting pump which can transport all kinds of resin, pigment, paraffin wax paint,printing ink emulsoid,all kinds of oil crude oil,heavy oil.

4.Power plant: Using as heavy oil,crude oil transporting pump,main machine lubricating pump.

5.Food industry: Using as transporting pump which can transport alcohol, honey, syrup, juice, fixed oil,milk and slurry oil.
