Horizontal End-Suction Pumps
SBG501...503

Axial/semi-open impellers

Horizontal End-Suction Pumps
are centrifugal inline pumps with a compact design where the impeller is mounted onto the extended motor shaft.
These pumps are not self-priming and must be gravity fed. All pumps are equipped with a single mechanical seal.
Upon request a second mechanical seal is available to allow for dry-running (-GD).
This pump series is designed for horizontal installations next to a tank and for pumping highly air entrained coolant and cutting oils, as they occur in high speed grinding applications.
The SBG pumps are equipped with the user-friendly SAE flange connection which allows for either vertical or horizontal pipe connection and the connection of a pressure gauge with G ¼.
For more information see mechanical features within the technical information section.
