Description

The 3S three-screw pumps consist of a broad range of low maintenance pumps for lubricating, non-abrasive and chemically inert liquids. 3S pumps are the best choise in many various industrial applications.

A universal design

The 3S series has been thoroughly engineered and is applicable for various applications. With a range consisting of 29 different pump sizes with delivery rates from 5 – 2.900 l/min @ 1450 rpm the 3S series is one of the most comprehensive three-screw pump ranges available on the market.

Furthermore, the individual pump sizes are available in several executions, which ensures a high degree of flexibility when specifying a pump for specific system designs.

Low maintenance

The 3S series pump is designed with a lifetime-lubricated external ball bearing with an expected lifetime of 30.000 hours. With a weep hole just between the shaft seal and the bearing, preventing accumulation of residue the bearing is well protected. The ball bearing is not exposed to the pumped liquid. The mechanical seal is well lubricated and cooled. The seal is designed to efficiently dissipate frictional heat.
