DRY-PIT SUBMERSIBLE SOLIDS HANDLING PUMP

The United Flo Dry Pit Submersible Pump is a high-performance, non-clog centrifugal pump specifically designed for dry pit submersible installations in wastewater applications. Engineered to handle solids-laden liquids, this pump features an enclosed motor and is ideal for flooding conditions, ensuring reliable operation even when water levels rise. Its robust design and advanced hydraulics offer superior durability, while the non-clog impeller design provides efficient performance with minimal maintenance. Perfect for demanding environments, the pump integrates seamlessly into existing systems without requiring modifications to external mounting, piping, or electrical configurations.

​

Key features include:

• Dry pit submersible vertical orientation with an enclosed motor for protection in flooding conditions.

• Non-clog enclosed impellers with a minimum 3” solids passage for efficient solids handling and clog prevention.

• Suction port range from 4” to 54” to accommodate a wide variety of flow requirements.

• Industry-leading NPSHR for optimal performance in low-suction-pressure conditions.

• Advanced hydraulics designed for improved performance and energy efficiency.

• Best-in-class bearing arrangement for extended pump life and reliability.

• Improved non-clog design to address clogging issues effectively.

• Designed with CFD and CFX technologies for optimized hydraulic performance.

• Proudly U.S.-owned and operated, providing innovative, reliable, and cost-effective solutions for superior pump performance.
