Maximum efficiency centrifugal pumps for large-scale wastewater applications. Flooded suction installations delivering 80-88% efficiency with superior maintenance access and long service life.
Dry-pit wastewater pumps represent the pinnacle of centrifugal pump efficiency and reliability for large-scale applications. Installed in dedicated pump stations with flooded suction from wet wells, these pumps achieve the highest efficiency ratings (80-88%) while providing unmatched maintenance accessibility and operational flexibility.
The dry installation environment protects motors and mechanical components from moisture and corrosive atmospheres, enabling the use of standard industrial motors and extending equipment life. With capacities ranging from 500 to 10,000+ GPM, dry-pit pumps are the preferred choice for municipal treatment plants, large lift stations, and industrial facilities where energy efficiency and reliability are paramount.
Achieve 80-88% efficiency at design point with optimized hydraulic designs and standard industrial motors.
Full access to all components for inspection, maintenance, and repair without wet well entry.
Multiple pump and motor combinations available to match specific application requirements.
Dry environment protection enables 20+ year service life with proper maintenance.
Most common configuration for municipal applications, offering easy maintenance access and proven reliability for continuous operation.
Space-saving vertical configuration ideal for installations with limited floor space while maintaining high efficiency.
Simple, cost-effective design for smaller applications requiring reliable performance with easy maintenance access.
