W-Type Twin Screw Pump

W-Type Twin Screw Pump

The W-Type Twin Screw Pump is a high-efficiency positive displacement pump designed for the stable and continuous transportation of various liquids with different viscosities, temperatures, and solid contents. Featuring synchronized twin screw rotors, the pump delivers smooth, non-pulsating flow with low noise, minimal vibration, and excellent self-priming capability. It is widely used in industries such as petroleum, chemical processing, food processing, marine engineering, pharmaceuticals, wastewater treatment, and energy systems.

Manufactured with precision engineering and durable materials, the W-Type Twin Screw Pump can handle clean liquids, lubricating oils, heavy oils, emulsions, viscous media, corrosive fluids, and liquids containing gas or small solid particles. Its advanced screw structure ensures stable pressure output and gentle fluid handling, making it especially suitable for sensitive or shear-sensitive media.

Product Features

High Efficiency and Stable Performance
The synchronized twin screw design provides continuous and uniform fluid delivery with minimal pulsation, ensuring stable system operation and reduced pipeline vibration.

Wide Media Adaptability
Suitable for transporting low-viscosity to high-viscosity liquids, including oils, chemical liquids, fuel, syrup, sludge, wastewater, and mixed media containing gas or particles.

Strong Self-Priming Ability
The pump offers excellent suction performance and can quickly achieve self-priming without the need for additional auxiliary equipment.

Low Noise and Low Vibration
Optimized rotor profile and precision machining greatly reduce operational noise and vibration, improving working environment and equipment lifespan.

Bidirectional Conveying Capability
The pump can operate in both forward and reverse directions, providing flexible installation and application options.

Reliable Sealing Structure
Equipped with high-quality mechanical seals or packing seals to ensure leak-free operation under different working conditions.

Easy Maintenance
Simple internal structure and modular design allow convenient maintenance, reduced downtime, and lower operating costs.

Applications

The W-Type Twin Screw Pump is widely used for:

• Crude oil and heavy oil transportation

• Fuel oil transfer systems

• Lubricating oil circulation

• Chemical liquid conveying

• Food-grade liquid transfer such as syrup, molasses, and edible oil

• Marine cargo loading and unloading

• Wastewater and sludge transportation

• Industrial hydraulic and lubrication systems

Working Principle

The pump operates through two intermeshing screw rotors rotating in opposite directions inside the pump casing. As the screws rotate, sealed chambers are formed along the axial direction, continuously moving the liquid from the suction side to the discharge side. This process ensures smooth, continuous, and low-shear fluid transportation with stable pressure output.

Advantages

Compared with traditional gear pumps and centrifugal pumps, the W-Type Twin Screw Pump offers higher efficiency, wider viscosity adaptability, lower pulsation, and superior self-priming performance. It is an ideal solution for demanding industrial fluid transfer applications requiring reliability, durability, and stable flow control.
