3GCL Vertical Three Screw Pump

3GCL Vertical Three Screw Pump

The 3GCL Vertical Three Screw Pump is a high-efficiency vertical positive displacement pump specially designed for the stable transportation of lubricating liquids and fuel media. Featuring an advanced three-screw structure and compact vertical installation design, the pump provides smooth flow, low pulsation, strong self-priming capability, and reliable continuous operation. It is widely used in marine engineering, power plants, petroleum, metallurgy, hydraulic systems, and industrial lubrication applications.

The vertical structure of the 3GCL pump effectively saves installation space and is especially suitable for equipment layouts with limited floor space. Its precision-engineered screw rotors ensure stable pressure output, low noise operation, and high transmission efficiency, making it an ideal solution for various industrial fluid handling systems.

Product Features

Long Service Life
Manufactured with high-quality materials and advanced machining technology, the pump offers excellent wear resistance, corrosion resistance, and long-term operational stability.

Working Principle

The 3GCL Vertical Three Screw Pump operates through one driving screw and two driven screws rotating synchronously inside the pump casing. As the screws rotate, sealed chambers are formed between the screw threads and pump housing, continuously moving the liquid from the suction side to the discharge side. This axial transportation process ensures stable pressure, low turbulence, and smooth fluid transfer.
