Wastewater screw pumps are primarily utilized to transmit sludge, sewage, wastewater, and other kinds of dirty fluids with liquids and solid particles with high viscosity. These pumps refer to be progressive cavity pumps or single-screw pumps. They function on the positive displacement principle. These pumps operate for various applications such as sludge cake, dirty water, activated sludge, sewage, bio-sludge, and more.
Wastewater pumps are useful for many applications, including seepage and sewage in different locations. These pumps work with rollers and impellers to transmit the liquid to the shrinking cavity on the discharge side of the pump from expanding cavity on the suction end.
Screw Pump Key Parts
Following are the Key parts of the Screw Pump
- Gearbox & Motor
The installation of the gearbox and electrical motor stimulates the screw pump to rotate constantly. The motor compels the auger to pump out and transfer the waste from the water to the highest pumping level in the wastewater treatment plant, beginning from the entry level of the water. It is important to automate the sewage treatment structure and to notice any unusual debris that may persuade the working efficiency of the machine.
- Screw
The screw transmits the wastewater from the bottom of the screw pump channel to the pump exit. The screw is adequate in pumping water loaded with debris and waste with the highest effectiveness and least maintenance.
Areas of Application
- Final effluent and inlet pumping of wastewater treatment plants
- Retrieval and Surplus sludge in sewage treatment plants.
Types of Screw Pumps
- Steel Through Liner
In certain occurrences, the structure of a screened concrete through is not practical, and readymade steel through line can be given.
- Concrete Through
It is the traditional design. The civil contractor first creates a through roughly 80mm larger than the outer diameter of the screw rump. The final dimension of the through is attained by screeding. The screw obtains the final dimension by rotating the screw with a temporary screed bar.
Wastewater treatment is ideal for transmitting large volumes of liquids with low lift. Including a few moving parts, screw pumps provide a built-in variable capacity when functioning at a constant speed, leading to minimum maintenance and wear.
