Extreme Solids Handling Technology

Solids handling pumps represent the most robust category of submersible wastewater pumps, specifically engineered for applications with extreme solids content, large debris, and the most challenging pumping conditions. These heavy-duty pumps go beyond standard sewage pumps to handle applications where conventional pumps would fail due to clogging, wear, or damage from abrasive materials.

Featuring oversized flow passages, reinforced construction, and specialized impeller designs, these pumps excel in applications such as raw sewage with heavy debris, industrial waste with large particles, construction site dewatering, and any application where solids content exceeds the capabilities of standard pumps.

Superior Solids Handling Capabilities

Large Passage Design

Oversized impeller passages and volute designs allow 4-6 inch spherical solids to pass without jamming.

Heavy-Duty Construction

Reinforced casings, oversized shafts, and premium bearings for extreme-duty applications.

Abrasion Resistance

Hardened surfaces and wear-resistant materials to handle abrasive solids and extend service life.

Non-Clog Performance

Specialized impeller designs that resist clogging from rags, debris, and fibrous materials.
