The Advantages Of Sludge Rotary Lobe Pump In Sewage Plant

Sludge lobe pumps belong to a type of conveying machinery with a high concentration of discharge viscosity. Sludge lobe pumps, also known as rotary lobe pumps, achieve sludge conveying through fine adjustments to the manufacturing process, in conjunction with steam and diesel motors, to meet the needs of the work station. The advantages of its application in sewage plants are as follows.

1. The use of an elastomer rotor not only gives it a long-lasting resistance to high temperatures of 120°C, but also has very good wear resistance. The unique spiral rotor profile optimisation design improves the internal flow characteristics, increases cavitation resistance, achieves low pulsation and high efficiency conveying, delays rotor life and reduces maintenance costs.

2、Seal design, using a combination of floating mechanical seal with independent intellectual property rights, to ensure continuous sealing medium temperature up to 120 ℃. All mechanical seals are one part and can be replaced or checked after opening the pump cover. Different mechanical seal materials are selected according to different conveying media. All O-rings are also selected in different materials according to the characteristics of the medium.

3. Replaceable wear plates are installed at both ends of the axial direction, and circular wear liners are also installed inside the pump body to protect the pump casing from abrasion and prolong the life of the pump. The pump body does not need to be dismantled and the wear plates and bushings are easy to inspect and replace.

4、Adopt the middle isolation cavity design, isolate the overflow pump cavity and gear cavity. Prevent the medium from polluting the gear chamber, and prevent the lubricant of the gear chamber from entering the overflow pump chamber and polluting the medium. The lubricating oil of the intermediate isolation chamber lubricates the mechanical seal, ensuring normal operation of the pump in idling or in vacuum.
