The fourth generation of submersible electric pumps—DA and DAS two series of new cyclone submersible sewage pumps have been successfully developed in Jiangsu Asia Pacific Pump Co., Ltd. The pump integrates the motor and the pump body, has small volume, compact structure, quick installation, flexible operation, convenient maintenance, and can simplify the civil engineering of the pump station, saving the total construction cost of the pump station project by 30% to 40%. The company has designed a unique swirling impeller structure to create a “vortex†in the wide space of the pump body, which facilitates the smooth discharge of large particles and debris entering the pump body, significantly reducing the possibility of entanglement and clogging, and improving work efficiency. More than 30%. On this basis, they also adopted the world's advanced double-face mechanical seal new technology, so that the sewage pump no longer leaks. The pump is automatically controlled by the control panel and the floating switch under water, and the water level automatic control can be realized without additional control system; not only can it be operated automatically, but also can be switched in parallel; the internal automatic protection device is set, in overload, circuit In the absence of phase or short circuit, water immersion, over temperature, it will automatically stop working to ensure safe operation.
