Durrex rotor pumps, homogeneous pumps used in environmental protection industry

Durrex rubber rotor pump is a self-priming transfer pump, developed specifically for sewage and sludge, widely used in sewage treatment plants for sewage and sludge transportation. Durrex rubber rotor pump has a wear-resistant and corrosion-resistant lining plate attached to its working chamber, which can be easily replaced and updated. The rotor adopts various formulas of rubber materials to avoid rubber expansion, corrosion, damage and tearing, and can meet the requirements of sewage transportation with different components. It is an ideal sewage and sludge transportation pump for sewage treatment plants.

The sewage rotor pump is used for conveying activated sludge, dosing, sludge reflux, centrifuge belt feed, etc., to replace the screw pump used in traditional processes. The working principle of a pump is to use the change in the volume of the pump chamber to achieve continuous transportation of the medium. It has super strong self-suction force, can be reversed, has high transportation efficiency, and low maintenance costs.

After concentration treatment, the water content of sludge is generally around 95% -97%. Separating the pore water in the sludge with a moisture content of 75% -80%, the adsorbed water and capillary water in the sludge are separated. After dehydration, the volume of the sludge is greatly reduced, which not only reduces secondary pollution to the environment, but also creates favorable conditions for sludge transportation, disposal, and comprehensive utilization. Through a screw propeller, it enters the rotor pump body and is squeezed at a speed of 45-60 revolutions per minute, efficiently and smoothly transported to a storage tank or directly loaded into a vehicle.

With the rapid development of rail transit engineering construction, people's requirements for the environment of subway stations are increasingly increasing. The traditional drainage method of installing submersible sewage pumps in the collection tank of subway stations to enhance sewage has encountered a series of drawbacks, such as inconvenience in maintenance, odor, and susceptibility to bacterial growth. Therefore, there is an urgent need for new sewage discharge technologies. As an optimized sewage system, Durrex vacuum drainage system has significant advantages in energy conservation, operation and maintenance, especially in improving the environment, and can effectively solve the drawbacks of traditional underground sewage discharge methods.

As a leading enterprise in industrial pumps, Durrex Emulsification pump, Homogeneous Pumps, Lobe Pumps, Rotary Lobe Pumps, Rotor Pumps, Rotor pumps and other products have passed first-class production and testing equipment, creating excellent quality and maximizing value for users.
