Description

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. 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. Magnetic coupled version The 3S pumps are also available in a magnetic coupled version. The pump is hermetically sealed and the liquid cannot escape or react by coming into contact with other materials. Design 3S casings are of nodular graphite iron, EN-GJS-400, and screws are of nitrated steel 1.7139. High quality mechanical seal with special SiC graphite material as standard. 3S pumps are available in several executions, e.g. with free shaft end, as a unit on bracket foot or vertical pedestal. Furthermore, each pump size is available in inline as well as top flange design. Advantages of the 3S three-screw pump design: Low lifecycle cost Long life time and low maintenance Compact design High capacity at limited space High efficiency Low noise Low pulsation Pumping without violent turbulence Very good suction conditions (NPSH)
