Submersible sewage pumps have many advantages, the most prominent of which is that they can be directly used in sewage. However, in situations where there is no or it is inconvenient to set up a trash screen, small-diameter submersible sewage pumps often get clogged by larger debris in the sewage, causing trouble for users.
To address this vexing issue, Kaiquan has developed shredding submersible sewage pumps with diameters of 50, 65, 80, 100, 150, and 200mm. These pumps not only possess all the advantages of conventional submersible sewage pumps but also have the following unique superiorities:
1. It can shred and smoothly discharge objects such as gunny bags, plastic woven bags, canvas gloves, leather gloves, cotton thread woven gloves, daily-use plastic bags, cloth, toilet paper, sanitary napkins, cotton yarn and the like; even objects like wooden strips can be easily shredded as long as they can enter the suction port. It can completely prevent the pump and pipelines from being clogged by debris in the sewage, and there is no need to install expensive debris-blocking and debris-removing devices when in use.
2. The impeller and cutting module are made of rust-resistant materials and undergo heat treatment. The cutting edges on the impeller and cutting module have sufficient hardness and are rust-resistant, thus being highly wear-resistant and able to remain sharp for a long time.
3. The impeller passage size and the pump body passage size are precisely matched, enabling the shredded debris to pass through smoothly.
4. The unique arrangement of the bearings and mechanical seals makes the cantilever of the shaft very short, and the rigidity and strength of the shaft are very high. As a result, the vibration of the shaft is very small, which greatly reduces the leakage of the mechanical seal. The shaft can withstand large impact loads and still has a long service life even when the pump is under heavy load conditions and occasionally crushes relatively hard objects.
5. Both the pump side and the motor side are equipped with mechanical seals to provide reliable double submersible shaft seal protection for the motor. The oil in the oil chamber fully lubricates and cools the mechanical seals. The mechanical seal area on the pump side has a structure that can shred and drive away debris, preventing it from accumulating or depositing in the mechanical seal cavity and thus avoiding its impact on the normal operation of the mechanical seal.
6. The chip-scraping grooves set between all the rotating and stationary parts through which the fluid flows can scrape off the thin and tough chips squeezed in between the rotating and stationary parts, thus avoiding an increase in pump power or a locked rotor.
