3G25×4 Screw Pump

3G25×4 Screw Pump

The 3G25×4 Screw Pump is a compact and efficient three-screw positive displacement pump designed for the stable transportation of lubricating oils and non-corrosive viscous liquids. With its precision-engineered screw structure, the pump provides continuous, low-pulsation fluid delivery, reliable pressure performance, low noise operation, and excellent self-priming capability. It is widely used in industrial lubrication systems, hydraulic equipment, fuel transfer systems, marine engineering, and mechanical machinery applications.

The 3G25×4 model is specifically designed for medium and small flow rate applications requiring stable operation and continuous oil transportation. Its compact structure and durable construction make it suitable for long-term industrial use under demanding working conditions.

Product Features

Stable and Continuous Flow Delivery
The three-screw rotor design ensures smooth, pulse-free liquid transportation, effectively reducing vibration and protecting system components.

Excellent Self-Priming Performance
The pump has strong suction capability and can quickly establish stable fluid transfer without additional priming equipment.

Low Noise and Low Vibration
Precision-balanced screw rotors and optimized internal structure provide quiet operation and smooth mechanical performance.

Compact Structure and Easy Installation
The compact integrated design allows convenient installation and efficient use of limited equipment space.

High Reliability and Long Service Life
Manufactured with high-quality materials and advanced machining technology, the pump offers excellent wear resistance and stable long-term operation.

Efficient Lubricating Liquid Transportation
Especially suitable for handling lubricating oils and viscous media with stable pressure output and low shear force.

Working Principle

The 3G25×4 Screw Pump operates through one driving screw and two driven screws rotating synchronously inside the pump casing. As the screws rotate, sealed cavities are continuously formed and move axially from the inlet to the outlet, transporting the liquid smoothly and continuously. This working principle ensures stable flow, low pulsation, and efficient pressure transmission.
