China Horizontal Twin Screw Pump for Marine Use

Certificate: ISO9001: 2000, CE, CCS, BV, NK, KR, ABS, RINA, GL, etc.


A. Using range
Twin screw pumps is the best choice to be used as Fuel Oil pump, Diesel Oil pump, Heavy Oil Transfer Pump, lube oil Pump, lubricating oil pump or chemical pump.


Twin-screw pump can transfer various non-solid contained fluid medium or extremely high viscosity medium. They have wide availability and high reliability for lubricating or non lubricating medium, for corrosive medium or gas-liquid mixture.
Capacity: 0.5-1500m3/h
Pressure: 0.1-2.0Mpa
Viscosity: 0.5-100, 00mm2/s
Temperature: -30 - 200 C
Medium: Various lubricating oil and fuel oil

Construction: Horizontal, vertical, portable structure, heating chamber
Safety: Explosion-protection, water-protection, safety valve, alarming sensor.

B. Using field
1. Petrochemical Industry: Transfer pump for various lubricating oil, crude oil, residual oil, heavy oil, bitumen, diesel oil, gasoline etc.
2. Shipbuilding Industry: Transfer pump, cargo oil pump, booster pump, striping pump and engine lubricating pump for various fuel oil, lubricating oil, waste oil, bilge sludge and sea water etc.
3 Chemical Industry: Transfer pump for various acid, alkali and salt solution, resin, glycerin, olefin, polymers and various cosmetics emulsion.
4. Paint Industry: Transfer Pump for various printing ink, paint, oil paint, dope etc.
5. Food Industry: Transfer pump for various high-viscosity medium like alcohol, beverage, honey, sugar juice, tooth paste, milk, soy sauce, animal oil, vegetable and chocolate etc.
6. Saving & Transferring industry: Loading and unloading oil goods for oil station, ship and tanker.

C. Features
1, The inlet-outlet civility adopts special design to make sure that enough medium is remained in the pump. Even when the medium in the suction pipe is all discharged, the pump still has very good self-suction performance.

2, The pump body adopts special-structure circular valve, which will open when the outlet pressure is higher than the working pressure. Then, some medium will back to the inlet of pump or saving can through this circular valve. Meanwhile, the pump can starts under full pressure situation thus greatly reduce the torque.

3, Use synchronizer gear to transfer toque from initiative screw to idler screw, which ensures no metal contact and power transmission between transferring elements. So the transferring elements have high reliability for any medium and the pump can free from damage of dry rotation in a short time.

4, When the pump is working, the meshing screws form a sealed civility in the pump body, following the rotary motion of the screws, the liquid in the sealed civility does axial motion with the sealed civility and transferred to the outlet of pump steadily and continuously. Because the capacity of the sealed civility never changes in the working pump, there will be no pulsation when the pump deliveries liquid.

5, The body of twin screw pump has several different heating structure plans for choice, to adapt to different medium under different temperature.
