Product details

Product Introduction

Cutting sewage elevatorIt is a highly integrated sewage discharge system. It consists of a sewage pump, a water collection tank, pipelines, valves, level gauges, and electrical control devices. It collects wastewater from sewage pipes and sanitation facilities that are below the sewage level or far away from the municipal sewage network through a collection tank, and lifts and pumps it to the urban sewage system. There are multiple interface options on the box, including vertical and horizontal interfaces, connecting water pumps, sewage inlet pipes, ventilation pipes, and parallel collection tanks.

With the prosperity and development of society, the construction of various underground buildings is also increasing. However, the corresponding sewage lifting facilities are relatively lagging behind. Currently, the traditional method of excavating sewage tanks underground is widely used, and problems such as odor overflow and mosquito and fly bacteria breeding are inevitable, which is extremely disproportionate to the country's advocacy for building an environmentally friendly society.
