3G Magnetic Drive Screw Pump

3G Magnetic Drive Screw Pump

The 3G Magnetic Drive Screw Pump is a high-performance positive displacement screw pump integrated with advanced magnetic coupling technology. It is designed for the safe and leak-free transfer of lubricating oils, light fuels, and other clean or slightly viscous liquids. By eliminating traditional mechanical shaft seals, the pump achieves completely sealed operation, making it especially suitable for applications requiring zero leakage, high safety, and environmental protection.

The pump combines the stable conveying characteristics of a three-screw pump with the sealing advantages of a magnetic drive system, ensuring smooth flow, low pulsation, and reliable operation under various industrial conditions. It is widely used in chemical, petroleum, pharmaceutical, marine, and precision industrial systems.

Product Features

Leak-Free Magnetic Drive Design
The magnetic coupling replaces traditional shaft seals, completely eliminating leakage risks and improving operational safety.

Stable and Pulse-Free Flow
The three-screw structure ensures continuous, smooth, and low-pulsation fluid delivery with stable pressure output.

High Safety and Environmental Protection
Suitable for transporting flammable, explosive, toxic, or valuable media without leakage risk.

Strong Self-Priming Capability
Provides excellent suction performance and stable startup under various operating conditions.

Low Noise and Low Vibration
Precision-balanced screw rotors and non-contact magnetic transmission ensure quiet and smooth operation.

Reliable Operation and Long Service Life
Non-contact torque transmission reduces mechanical wear, extending service life and improving reliability.

Compact and Efficient Structure
Integrated design allows easy installation, space saving, and convenient maintenance.

Working Principle

The 3G Magnetic Drive Screw Pump operates through a three-screw mechanism combined with a magnetic coupling system. The external motor drives the outer magnetic rotor, which transmits torque through a magnetic field to the inner rotor connected to the screw assembly. As the screws rotate, sealed chambers are formed and continuously move the liquid from the suction side to the discharge side, ensuring smooth and stable fluid transfer without shaft seal leakage.
