SP, SH trailer engine-driven trash pumps are used at construction sites to remove water containing sticks, stones, rags,debris.               
1. Removable suction cover allows quick unclogging of pump
2. Primary wear parts, seal, impeller and wear plate, can be changed through removable suction cover
3. Rotating assembly easily removed for shop repairs without disturbing piping
1.Rugged open impellers for solids handling to 3”
2.  Both speed and impeller trim can be employed to meet service conditions
3.  Impeller design keeps seal pressure low and reduces solids buildup in stuffing box
4.  Suction flapper check valve speeds self-priming and eliminates foot valves.

SP& SH 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.
