The SN series three-screw pump is designed for conveying oils and other liquids with lubricating properties. With a modular and standardized component design, the pump can be configured for horizontal, flange-mounted, or vertical installation.
According to the requirements of the conveyed medium, the SN series three-screw pump can also be supplied with heating or cooling structures. This allows the pump to support different operating conditions for oil transfer, fuel supply, hydraulic, lubrication, loading, and liquid supply systems.
The pump uses a hydraulically balanced rotor design, helping reduce vibration and noise during operation. It provides stable output with low pulsation, good efficiency, and strong self-priming capability. Its compact structure, small size, and light weight also support operation at relatively high speed.
