20% Energy saving for high viscosity oil transport

The screw pump can be used for transferring industry oil, gas-oil mixed media(as a multiphase pump), easily vaporized liquids, media that require self-priming, and can be used for crude oil transportation, petroleum additives transportation. They also can easily handle mediums like hot tar, hot oil, various resin, etc.

Oil, gas and water mixed transportation

Transportation of crude oil, heavy oil, asphalt and other oil products

In high temp, corrosion, abrasion occasions

We focus on one type of pump applying for different fields

For over 15 years, Dalian Baosteel Metallurgy has been focus on R&D of screw pump. According to different application scenarios, we develop different series of screw pump patented products by giving full play to the characteristics of high efficiency and energy saving of screw type pump. And we offer cost-effective custom designs for specific requirements.

If the viscosity of the medium to be transported is greater than 20 cst, do not hesitate to select our screw pump.

If the medium to be transported does not allow mixing, please select our screw pump


Petroleum Industry: transportation of heavy oil, crude oil, asphalt, fuel oil, grease, lubricating oil, petroleum additives, gasoline, kerosene, diesel oil, various resins, etc.

Oil depot wharf: unloading oil pump, loading pump

Thermal power plant: heavy oil transfer pump, heavy oil fuel oil pump.

Oil field: Crude oil transportation, oil and gas mixed transportation, polymer transportation.

Hydropower plant: lubricating oil pump

1. Low noise and long life

Due to the structural characteristics of the twin-screw pump, there is no direct mechanical wear during operation.

2. High temp, corrosion, abrasion occasions

The pump can be designed as a thermal insulation and sealed cooling system

3. Stable conveying

No stirring and no pulsation when conveying low viscosity media. Suitable for conveying gas-liquid mixed medium.

4. High viscosity liquid delivery

Twin screw pumps are highly efficient even when pumping liquids with viscosities up to 1 million cSt

Energy-saving Case


"I used a centrifugal pump to transport high-temperature oil slurry before, which required a pump unit of 37kW to drive. Then after switching to the twin screw pump, it can be easily used with only 22kW under the same working conditions."
