2" Self-Priming Sewage Trash Pump (ST) Made in China
ST& SU Series pumps are designed for economical & trouble-free operation in handling solids-laden liquids and slurries. Pumps 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.

Pumps will be able to handle up to 75mm spherical solids, depending on pump models. In case that 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.

Material: Cast Iron, ADI, CD4MCU, 316 SS, Alloy 20, C276.
