1、 Overview of EQZWS new self-priming pump:
EQZWS high flow self-priming pump is a new energy-saving double suction self-priming pump product developed by Equan Company according to market demand. This pump has filled the historical gap of this type both internationally and domestically, and has achieved national invention (. X) and utility model (. 1). It completely solves the problems of large axial tension, long self-priming time, and low efficiency of single suction self-priming pumps. It has the advantages of high suction stroke, short self-priming time, high efficiency, significant energy-saving effect, stable operation, and long service life.

3、 Characteristics and applications of double suction self-priming pumps:
High flow self-priming pumps are divided into clear water type and suitable for conveying clear water or mild sewage. They have higher efficiency and better self-priming performance than sewage type pumps; The sewage pump integrates self-priming and non clogging discharge, adopts an axial reflux external mixing type, and through the unique design of the pump body and impeller flow channel, it does not require the installation of bottom valves and irrigation water, but can also suck and discharge liquids containing impurities such as particulate solids and fibers. It can be widely used in municipal sewage engineering, lotus pond breeding, light industry, papermaking, food, chemical, electrical, fiber, pulp and mixed suspension and other chemical media. It is the most ideal impurity pump. The EQZSC diesel engine type double suction self-priming pump is suitable for various complex emergency rescue, firefighting and other occasions, and is not affected by factors such as power supply and usage site. It can be moved for operation and has high flexibility.
The EQZWS new self-priming pump has obtained national invention (. X) and utility model (. 1). The pump has the advantages of high suction stroke, short self-priming time, high efficiency, significant energy-saving effect, stable operation, and long service life.
EQZWS clean water type is suitable for conveying clean water or mild sewage, with higher efficiency and better self-priming performance than sewage type; The EQZWS sewage pump integrates self-priming and non clogging sewage discharge, adopts an axial reflux external mixing type, and through the unique design of the pump body and impeller flow channel, it does not require the installation of bottom valves and injection water, but can also suck and discharge liquids containing impurities such as particulate solids and fibers.
