The 3S three-screw pumps are available in a wide range of low-maintenance models for pumping cutting fluids, non-abrasive and chemically inert fluids. They are the best choice for many industrial applications.
Models of the 3S series are carefully designed and can be applied in various fields. They are available in 29 sizes, deliver capacities ranging from 5 - 2900 l / min at 1450 rpm and are some of the most versatile three-screw pumps on the market.
The 3S series pumps are equipped with a lifetime lubricated external ball bearing rated at 30,000 hours. Thanks to the presence of a drainage hole between the shaft seal and the bearing, the latter is protected against sludge accumulation. The bearing does not come into contact with the pumped liquid. The mechanical seal is well lubricated and cooled. The seal effectively dissipates frictional heat.
