Non-clogging centrifugal pump, also known as sewage trash pump / solids handling pump, is single-stage single-suction axial inlet centrifugal pump. It is specially designed for wastewater, sludge and slurry containing fibers, hair, plastic bags, straw, soft debris and small solid particles.
Its core feature is **wide-channel single/double vane free-flow impeller**, with large clearance to avoid fiber winding and blockage, different from clean water centrifugal pumps. Four main types: horizontal, vertical inline, self-priming, submersible. Widely used in municipal sewage, papermaking, food processing, kitchen waste and biogas projects.
