Engineered Wastewater Pumps
Beford Pumps is a Hidrostal company that manufactures a variety of Heavy Duty Dry Install Wastewater Pumps, Submersible & Immersible Wastewater Pumps and Submersible Axial Flow pumps for wastewater and flood control.
This range features a more traditional wastewater design that features a shrouded, mulit vane impeller and is available in either a Dry-Pit/Bearing Frame design with mutliple instalation configuration in either a horizontal or vertical position. These hydrualics are also available in either Wet Well/Submersible or Dry-Pit/Immersible type featuring motors by Bedford Pumps.
Materials of construction are standard cast iron, but we have great flexibility to provide alternate materials to meet your specification.
- Solids handling
- Viscous pumping
- Delicate handling
- Low shear pumping
- High efficiency operation
The impeller has a single spiral vane having large open passages and an extended turn from the axial to the radial direction.
These features give a combination of characteristics not found in any other type of pump, namely:
- Extremely steep and stable curve
- High efficiencies
- Non-overloading power curve
- Low NPSH
- Non-clog pumping
The term “Non-Clog” has almost become a punchline in the pumping industry. Traditional wastewater pumps are actually classified as “Non-Clog”, but ask any operator or pump mechanic if their “Non-Clog” pumps clog! The Hidrostal design takes solids handling operation to the next level, where clogging & blockages are a thing of the past. The Hidrostal is not a traditional non-clog pump, but actually a hybrid that utilizes the best features of a positive displacement type screw pump – crossed with a single vane centrifugal pump. This combination provides an unmatched performance of effectiveness & efficiency.
Submersible/Immersible Units include these features:
*Mechanical Seals- Dual mounted within a fluid filled barriar chamber that provides lubrication and allows early warning detection of moisture intrusion.
*Bearings- Pre-lubricated, heavy duty, angular contact thrust bearings & deep groove ball journal bearings designed for maximum life.
*Sensors-Themal overload thermistors imbedded into motor windings. Moisture detection sensors are mount into seal chamber. Additional bearing temp probes or other options are available.
*Wear Rings-Both impeller and pump casing include wear rings to extend life and maintain maximum performance.
*Impeller-High efficiency shrouded, multi vane impeller capable of handling solids and fibrous materials. Impellers are both statically and dynamically balanced to minimize loads and imbalance.
*Motor Cooling-Immersible motors feature a circulated oil bath. An internal impeller allows cooling fluid to pass a heat exchange are circuate around motor. This is a closed circulation system that does not utilize the pumped media directly.
