Dewatering Applications
Your dewatering needs are our top priority. Our electrical submersible pumps support all your dewatering application needs for drainage, slurry, and sludge. Visit our dewatering applications section to learn more about various types of dewatering needs.
This kind of pump combines self-priming and non-clogging. It adopts an axial circumfluence outer-mix type. And through the particular design of the case and impeller channel, it not only needs to be fixed with a base valve and poured in water like normal self-priming, but also can suck and discharge liquid containing big grains and extended fibrin substance. So it is widely used in municipal sewage projects, river and pond breeding, the light industry, papermaking, weaving, foodstuff, chemical industry, power industry, fibrin, slurry, mixed suspension, etc., and chemical medium.
These applications call for pumps designed specifically for handling corrosive and abrasive materials and their solid contents.

Radford 5150 Pump Curves
Where the Radford Series Performs Best
The Radford Series self-priming pumps are engineered for environments where reliable sewage handling, strong self-priming performance, and non-clogging operation are critical. Their axial circumfluence outer-mix design allows these pumps to handle liquids containing large solids and fibrous material without interruption, making them suitable for both continuous-flow and intermittent-duty operations.
These pumps are widely used in:
Municipal Sewage and Wastewater
The Radford Series is designed for continuous sewage handling, efficiently moving wastewater containing solids and fibrous material. Its self-priming and non-clogging features make it ideal for lift stations, treatment plants, and urban drainage systems.
Aquaculture, Rivers, and Pond Management
These pumps support steady circulation and removal of waste-laden water in fish farms, ponds, and river management systems. Their ability to handle suspended solids ensures stable water quality and operational reliability.
Papermaking and Textile Industries
Effluent streams in pulp, paper, and textile operations often contain fibers and mixed suspensions. The Radford Series handles these materials without clogging, ensuring smooth movement of process water.
Food Processing Facilities
Food-industry wastewater often contains organic solids. The pump’s specialized casing and impeller design allow it to manage these loads effectively, supporting hygiene and operational flow.
Chemical and Process Industries
The pump is suitable for chemical media and mixed suspensions, providing reliable liquid transfer across varying viscosities or particulate contents. Its efficient operation contributes to stable process performance.
Power Generation Plants
Power facilities require pumps capable of handling slurry, cooling water, and waste streams without interruption. The Radford Series ensures dependable operation in environments where downtime is costly.
Light Industrial Operations
General manufacturing processes often produce wastewater containing solids, fibers, and chemicals. The Radford Series delivers consistent, non-clogging performance to support stable plant operations.
Maintenance and Repair
Radford Series pumps are built for continuous-duty sewage and industrial environments, where abrasive solids, fibrous material, and corrosive liquids can accelerate wear. Proper maintenance helps preserve their strong self-priming and non-clogging performance.
Key components to inspect regularly
- Impeller condition and clearance
- Casing channel for buildup or obstruction
- Seal integrity and leakage points
- Motor cooling system and thermal protection
Durability advantages
- High-chrome impellers reduce wear in abrasive applications
- Corrosion-resistant alloy components extend service life
- Steady cooling design protects the Class F motor during extended operation
Serviceability benefits
- Quick replacement of wear parts
- Easy impeller adjustment for restoring efficiency
- Straightforward removal of fibrous debris to prevent clogging
Because Radford pumps often operate in mission-critical municipal and industrial systems, access to professional support is essential. A proactive maintenance schedule reduces downtime, protects operational continuity, and ensures safe, reliable wastewater and slurry transfer where pump failure cannot be tolerated.
Accessories
Radford Series Self-Priming Pumps can be paired with a complete range of accessories that enhance wastewater, sewage, and slurry handling. Each accessory integrates seamlessly with the pump’s non-clogging, axial-flow design to support reliable operation in municipal networks, industrial plants, and mixed-material environments.
Key accessory options include
