Ruhrpumpen Overhung Self-Priming & Solids Handling Pumps
Ruhrpumpen’s overhung pump range includes both self-priming and solids-handling models, each designed for specific challenges. Self-priming pumps are ideal for above-ground installations, capable of clearing air from the suction line to start pumping without manual priming. Solids-handling pumps, by contrast, are built to move fluids containing debris or suspended solids, with rugged designs that resist clogging and wear. Both types offer reliable performance and easy maintenance in demanding industrial and wastewater applications.
Features
- Capacity up to 1,440 m3 /h (5,280 U.S. gpm)
- Head up to 45 m (147 ft)
- Temperature up to 70 °C up to 158 °F
- Self-priming process pump
- HI design (OH1A)
- Handles solids up to 3 inch (76 mm) in diameter
- Removable cover plate allows for easy access to impeller and seal
- Easy maintenance without the need of disconnecting piping
- Availability of mounting above the liquid being pumped
Applications
- Waste handling
- Sewage
- Clear liquids
- Suspended solids
How the SWP Self-Priming Pump Works
The SWP is a self-priming pump designed for solids-handling applications, capable of pumping both clear liquids and those containing solids. Its large volute design enables automatic repriming in fully open systems without requiring suction or discharge check valves.
Features
- Double row thrust bearing provides minimal shaft end play for extended mechanical seal life.
- ANSI 150 or 300 flange drilling is available based on material seleciton. RF or FF designs are available based on requirements.
- Self-priming system
- Enclosed impeller design
- Standard Inpro/Seal ® bearing insolators.
- Oversized oil sight glass mounted on both sides of the bearing unit.
Applications
- Clear liquids
- Suspended solids
How the GWP Self-Priming Pump Works
The GWP is a self-priming pump capable of handling clear liquids as well as suspended solids up to 3 inches in diameter. Its design features a chamber with a permanent oil bath for the mechanical seal, enabling continuous dry operation without damage.
Features
- Capacity up to 2,275 m³/h (10,000 gpm)
- Head up to 73 m (240 ft)
- Maximum Pressure up to 10.3 bar (150 psi)
- Temperature 0 to 120 °C (32 to 248 °F)
- Can be mounted in horizontal or vertical configurations
- Single stage, end suction pump
- Enclosed impeller, non-clog design
- Single volute style casing
- Handles solids up to 6" in diameter
- Bearings grease lubricated
- One piece casting stuffing box
- ANSI flanged nozzles Class 125
Applications
- Wastewater transportation/treatment
- Pollution control
- Storm water
How the SHD Solids Handling Pump Works
The vertically mounted SHD pump features a robust base designed to support the pump, motor, and accessories, while the horizontally mounted version is installed on a common base plate with the driver. Both configurations are capable of handling fluids containing solids ranging from 3 to 6 inches in diameter.
