SN Series Three Screw Pump | For Lubricating & Low-Lubricity Fuels
A versatile three screw pump with strong self-priming. It handles a wide range of fluids, from lubricating oils (Heavy oil) to
low-lubricity liquids (Light diesel). Its stable, pulsation-free output is ideal for fuel supply and hydraulic systems.
Accreditation and Certificates:
Overview
Our SN series pump is a self-priming, positive displacement pump. It features hydraulically balanced rotors. This design provides a stable flow with very low vibration. This pump is engineered for flexibility. It can handle lubricating media like lube oil. It also handles viscous media like emulsions and low-lubricity media like diesel fuel. Its compact, high-efficiency design makes it a reliable choice for fuel injection, transfer, and lubrication.
