MPX Pumps, SPXT-4 Self-Priming Trash Pump 4" Inch (Gorman Rupp Style) 

Self priming pumps are designed for economical and trouble-free operation in handling solids-laden liquids and slurries. They feature a large volute design which allows them to re-prime automatically in a completely open system without the need of suction or discharge check valves. And this is workable with the pump only partially filled with liquid and completely dry suction line. Self priming pumps are able to handle up to 75mm spherical solids, depending on pump models. In case the SPT series pump shaft or bearings need service or repair, the entire rotating assembly can be removed without disturbing pump casing or pipelines. Rotating assembly is sealed with an O-Ring, allowing for external adjustments of clearance.

Self priming centrifugal pumps effectively eliminate the requirement of valves, vacuum and ejector pumps which can get clogged or be impractical to use for prolonged operation.
