Many pumps produced by Beijing Quanming Company have built-in sewage discharge equipment that works alternately or in groups, which greatly improves the working efficiency, prolongs the service life of pumps, fundamentally solves the disadvantages of traditional equipment in sewage discharge, and is an environmental protection substitute for traditional equipment.

The equipment is divided into two cycles:

Water inlet circulation: the sewage containing sundries enters the water tank through the water inlet of the equipment, and the sundries are first isolated by the backwashing device, and the sewage without sundries enters the water tank;

Drainage circulation: when the water level of the water tank reaches the set high water level, the water pump starts to drain, and the sewage without sundries washes the backwashing device, and sundries are discharged from the outdoor septic tank with the sewage;

When the equipment is in the drainage cycle, the water inflow continues. In each drainage cycle, for equipment with multiple pumps, multiple pumps rotate or group alternately.

Equipment characteristics:

(1) The maintenance is simple, and the sewage isolation system is designed without a filter screen, so that the filter screen of the traditional filter backwashing sewage discharge equipment will not be blocked.

⑵ There is no inlet check valve and check valve blockage in the inlet and inlet pipes.

(3) Miniaturize the equipment, solve the problems of handling and installation, save the building space, and increase the building area and commercial value.
