The Modular S Centrifugal Pump represents one of the most distinctive products of self-priming pumps. On the basis of 50 years of experience in the production of self-priming pumps we produce a pump series that meets the future demands for economical and reliable pumps. TheModular S is widely used within differentapplications and markets.

Design Features

PrimingThe priming is based on the diffuser principle, which means that the priming ability is independent of valves and other mechanical elements as it is the flow of liquid that carries the air. In addition the diffuser principle has the effect that the Modular S can pump slightly polluted as well as air-mixed liquids.

The NSL range of pumpsrepresents high efficiency, low NPSH values, easy to installation and low maintenance.The NSLseries is widely used within differentapplications and markets.

Design Features

The pump is an in-line, radially split, single-stage centrifugal pump with connecting flanges according to international standards.

The pump is designed for mounting with electric motors having different international flange dimensions.

The pump casing is equipped with a replaceable sealing ring. The impeller is made with double-curved blades to ensure low NPSH-values and high efficiency.

The bearing unit is equipped with sturdy ball bearings and the small types are fitted with lifetime-lubricated bearings. In the larger types the lower bearing is a double bearing for which a lubrication point is provided.
