WQD series single-phase submersible sewage pumpDetailed product description：

Overview
The WQD single-phase submersible sewage pump is a new generation product developed based on the introduction of advanced foreign technology, digestion and absorption, and combined with the characteristics of Chinese users. It has the advantages of wide high-efficiency zone, strong passing capacity, long service life, convenient arrangement, and complete control functions, especially in terms of full head performance and sealing technology, which have their own characteristics.
The main purpose of single-phase submersible pump is:
This series of single-phase sewage pumps is widely used in factories, farmland, mines, construction sites, municipal environmental protection and other places. It can pump liquids containing solid particles or soft solid substances such as short fibers, paper scraps, sediment, etc., such as mud water, greywater, domestic wastewater, feces and urine. It is an ideal pumping equipment for agricultural irrigation, river dredging and construction site drainage.

Working conditions of single-phase submersible pump:
The medium temperature of WQD single-phase submersible pump shall not exceed+40 ℃, the pH value shall be 4-10, and the density shall not exceed 1.3 × 10kg/m3;
The power supply is single-phase 200-240V, frequency 50Hz, three-phase voltage 380V, frequency 50Hz, and voltage fluctuation range is 0.9-1.1 times the rated value;
The diving depth of WQD single-phase sewage pump shall not exceed 5M;
WQD submersible pumps of 5.5KW and above should be equipped with corresponding motor protection starters.

Main features of single-phase submersible pump:
The WQD sewage pump shaft has undergone longitudinal hard chrome treatment, which can effectively improve the wear resistance and corrosion resistance of the shaft, and is also beneficial for the maintenance and disassembly of the impeller.
The single-phase submersible pump has reliable sealing, no leakage, and both the dynamic and static rings of the mechanical seal are made of wear-resistant materials such as hard alloy to ensure that the medium is leak free.
The single-phase submersible pump has a small overall structure, small volume, low noise, significant energy-saving effect, and easy maintenance.
The impeller of a single-phase submersible pump has a single or double channel structure, which can pump larger solid particles and operate at full head.
Single phase submersible pump users can be equipped with a fully automatic safety protection controller as needed to protect the pump from water leakage, electric leakage, overload, and temperature rise, ensuring the safety and reliability of the product.
