GRIT/VORTEX SOLIDS HANDLING PUMP

The United Flo Grit Pump is a rugged, high-performance dry pit centrifugal pump designed to handle abrasive, solids-laden fluids such as grit, sand, and debris commonly found in wastewater and industrial processes. Built for durability and efficiency, this non-clog pump features wear-resistant construction and is engineered for long life in harsh operating environments.

Ideal for drop-in replacement, the United Flo Grit Pump is dimensionally matched to existing legacy grit pumps, eliminating the need for modifications to piping, mounting, or electrical systems. With advanced impeller configurations and proven hydraulic performance, it delivers reliable, low-maintenance operation while minimizing system downtime.
