Self Priming Centrifugal Pumps — SM/SG Series
Non-clog self-priming centrifugal pumps that re-prime after each restart and pass solids without clogging.
Self Priming Centrifugal Pumps (SM / SG Series) are engineered for efficient fluid transfer, combining robust self-priming capability with high-performance centrifugal design. Ideal for dewatering, sewage, and industrial applications, these pumps deliver reliable operation, quick priming, and minimal maintenance — making them the preferred choice for demanding environments.
