W2Ga/b Series Single – Suction Twin Screw Pumps:

In the field of fluid transportation, the W2Ga/b series single – suction twin screw pumps have become a reliable choice for numerous industries, thanks to their unique design and outstanding performance. The following will provide you with a comprehensive analysis of the features, working principle, application scenarios, and advantages of this pump.

I. Product Overview

Engineers meticulously crafted the W2Ga/b series single – suction twin – screw pumps to meet the conveyance demands under diverse complex working conditions. The “single – suction” design enables the pump to efficiently draw in fluid from one side during operation, ensuring a stable and efficient transportation process.

II. Working Principle

This series of pumps mainly consists of two meshing screws. The driving screw is driven by an electric motor, and the driven screw rotates synchronously under the drive of the driving screw. During the rotation, the helical surfaces of the screws mesh with each other to form multiple independent sealed chambers. As the screws rotate, these sealed chambers move axially from the suction end to the discharge end. At the suction end, the volume of the sealed chamber gradually increases, the pressure decreases, and the fluid is sucked into the pump under the action of atmospheric pressure or other pressure sources. At the discharge end, the volume of the sealed chamber gradually decreases, the pressure increases, and the fluid is extruded out of the pump, thus achieving continuous and stable fluid transportation.

III. Product Features 

1.High Viscosity Adaptability

The W2Ga/b series single – suction twin – screw pumps have an excellent ability to transport high – viscosity fluids. Whether it is high – viscosity industrial grease, such as special lubricating oil with a kinematic viscosity of up to 1000 cst at 40°C, or high – viscosity asphalt with a kinematic viscosity ranging from 300 – 600 cst at 135°C, this pump can handle them easily. Its unique screw design and sealed – chamber structure can effectively reduce the shear force inside the fluid when transporting high – viscosity media, avoiding changes in the media properties caused by excessive shearing.

2.Stable Flow Rate 

The flow output of the pump is extremely stable, with almost no pulsation. This is due to the precise meshing of the screws and the uniform movement of the sealed chambers. During the transportation process, the amount of fluid contained in each sealed chamber is basically the same, and they are discharged within the same time, resulting in minimal flow fluctuations. For example, when transporting liquid resin with a stable flow – rate requirement (such as unsaturated polyester resin with a kinematic viscosity of about 200 – 600 cst at 25°C), the W2Ga/b series pumps can ensure its stable transportation, providing a reliable guarantee for subsequent production processes.

3.Strong Self – Priming Ability

This series of pumps has an excellent self – priming ability. This means that in practical applications, without the need for additional priming operations, the pump can rely on its own self – priming function to suck in and transport fluids below the pump inlet position. In some working conditions where the liquid storage tank is at a low position, such as chemical raw material storage tanks, the pump can directly self – prime the fluid from the low – lying tank, greatly simplifying the design and operation process of the transportation system.

4.Low Noise and Low Vibration

The W2Ga/b series single – suction twin – screw pumps generate extremely low noise and vibration during operation. This mainly stems from the high – precision processing and balance design of the screws, as well as the rigid structure of the pump body. When the two screws mesh with each other, the movement is smooth, reducing the noise and vibration generated by friction and collision. This low – noise and low – vibration characteristic not only creates a good working environment for operators but also makes it suitable for places with strict requirements for noise and vibration, such as laboratories and medical equipment production workshops.

5.High Reliability and Long Life 

Made with quality materials and advanced techniques, key parts like screws and bushings are durable. The design distributes stress evenly, reducing wear. This gives the pump high reliability and a long service life.

IV. Application Scenarios 

1.Petrochemical Industry 

In petrochemicals, where high – viscosity and corrosive media need transport, these pumps fit well. They can move heavy oil or chemicals, and their self – priming helps in various tank set – ups.

2.Food and Beverage Industry

he food industry requires hygienic transport. The W2Ga/b pumps’ food – grade parts, smooth surface, and easy – clean design make them ideal for high – viscosity food materials.

3.Pharmaceutical Industry

Pharmaceuticals demand stable, accurate, and clean fluid transport. These pumps meet these needs, controlling ingredient ratios and being easy to clean.

4.Marine Industry

On ships, the pumps’ high – viscosity handling, low noise, and vibration make them perfect for lubricating and hydraulic systems.

The W2Ga/b series single – suction twin – screw pumps play an important role in the fluid transportation field of various industries with their excellent performance, wide application adaptability, and high reliability. They are powerful assistants for improving production efficiency and ensuring production quality.
