Product details
1、 ZW/ZWL unobstructed self-priming sewage pump | Overview of direct coupled self-priming sewage pump products
Self priming sewage pumps are mainly divided into two types: ZW self-priming sewage pumps with couplings and ZWL self-priming sewage pumps without couplings. ZW self-priming sewage pumps are one of the earliest self-priming sewage pump products. ZW self-priming sewage pumps with couplings have a certain ability to transport high-temperature liquids without transferring heat to the motor due to high liquid temperature, and without causing water ingress into the motor due to mechanical seal leakage. The characteristics of ZWL self-priming sewage pump are small footprint, low vibration and noise. Due to the use of direct connection, it avoids the disadvantages of coupling form requiring balance and has a low reliability and failure rate.
2、 ZW/ZWL unobstructed self-priming sewage pump | Characteristics of direct coupled self-priming sewage pump
The self-priming sewage pump is a non clogging self-priming sewage pump product developed to replace submersible sewage pump products and avoid the problem of motor burnout caused by water leakage when the pump is submerged in water. It is also designed for easy maintenance and repair. Based on the technology of similar self-priming pump products at home and abroad, Equan Company has developed a novel self-priming pump product with self-priming function. ZW self-priming sewage pump mainly has the function of self-priming pump and the characteristics of non clogging sewage pump. It mainly adopts the principle of axial reflux and external mixing. Self priming sewage pump products not only do not need to install bottom valves in the inlet pipeline like general water self-priming pumps, but also do not need to be filled with water every time they are used. The self-priming sewage pump can not only suck and discharge media containing large solid particles and long fiber impurities, but also be widely used in municipal sewage engineering, river pond aquaculture, light industry, papermaking, textile, food, chemical, electrical, fiber, pulp and mixed suspension and other chemical media. It is the most ideal impurity pump Compared with similar domestic self-priming sewage pump products, ZW self-priming pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy use and maintenance. It belongs to the domestic * in the sewage pump series products. All technical performance indicators are prioritized domestically and have reached the international advanced level, with broad application markets and development prospects

5、 ZWL/ZW non clogging self-priming sewage pump is used for:
Compared with similar domestic products, self-priming sewage pumps have the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy use and maintenance. They are among the top domestic sewage pump series products. All technical performance indicators are prioritized domestically and have reached the international advanced level, with broad application markets and development prospects. 1. Environmental temperature ≤ 45 ℃, medium temperature ≤ 60 ℃. 2. The pH value of the medium is 6-9 for cast iron pumps and 1-14 for stainless steel self-priming pumps. 3. The maximum diameter of the particles is 60% of the diameter of the self-priming non clogging sewage pump, and the fiber length is 5 times the diameter. 4. The total weight of impurities in the medium shall not exceed 15% of the total weight of the medium, and the specific gravity of the medium shall not exceed 1240 kilograms per cubic meter.
