The difference between sewage pump and drain pump:

Generally speaking, the drainage pump is mainly used for discharging sewage and rainwater because the liquid contains impurities. Most commonly used are sewage pumps. However, if the liquid is sewage with clear water, for example, river water without obvious impurities, rainwater after sedimentation, and sludge water treated by some sewage treatment plants (turbid, but not very viscous) is centrifuged with common feed water. Pipe pumps are also available.

1. By definition: the sewage pump is specially used for sewage pumping. The definition of the drainage pump is relatively wide. It includes a sewage pump and a clean water pump, collectively referred to as a drainage pump. GZT self priming trash pump can be used for trash pumping, sewage by-pass, or wellpoint / sock dewatering.

2. Different points from the design of the runner: In order to prevent clogging, the sewage pump is mainly designed with large flow passages, which naturally leads to relatively low efficiency, so the lift is generally not high, and the flow path of the drain pump is small, and the gap is also Smaller, the head is relatively higher. GZT wet prime pump check valve can easily be replaced through the impeller inspection cover without dismounting the pipework.

3. From the different points of the impeller design: In order to prevent the winding, the impeller design of the sewage pump is simpler than that of the clean water pump. Without the retaining ring, it is equipped with a serrated piece, which can be used to crush the cloth and other debris and pump it out, while the drainage pump The impeller is mainly to improve work efficiency, its design is more complicated, and the work efficiency will be significantly improved compared with the working efficiency of the sewage pump. GZT self priming sewage pump has two vane, 6 inch trashpump semi-open impeller handling solids up to 3” (75 mm) in diameter.

3. From the different points of the pump design: the pump body of the sewage pump is designed with a pressurized water chamber. The impurities can be removed from the pressure water chamber, and the pump flow path is unblocked. When the impeller rotates, the sewage will produce a strong axial vortex effect, and the sewage discharge effect is remarkable. . The pump body of the drain pump is directly connected to the motor, and the liquid is transported or is similar to a clean water. The hydraulic model used in the pumping chamber and the suction chamber of the clean water pump is designed to be both beautiful and efficient.

4. From the different points of the transport medium: the drain pump is used for transporting clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire boosting, long distance Transportation, HVAC cycle, farm irrigation, bathroom and other cold and warm water cycle pressurization and equipment. The sewage pump transports impurities containing particulate solids and long fibers, which can be widely used in sewage treatment projects, river pond culture, light industry, papermaking, textile, food, chemical, electric industry, fiber, slurry and hybrid suspension. medium. GZT engine driven trash pump is the finest dewatering pump and wellpoint equipment.
