SN series three-screw pumps are often used in medium and low-pressure lubrication systems. They are constant-flow axial conveying screw pumps with a continuous working pressure of 0-4MPa. Mechanical balance and self-lubrication of the main bearing parts are used between the three screws, with low-pressure pulsation, low noise and long service life. We can also provide various sealing types according to customer requirements.
