ZW unobstructed self-priming sewage pump

1： Overview of ZW self-priming sewage pump

ZW horizontal unobstructed self-priming sewage pumpIt is a novel product successfully developed on the basis of repeated research on similar product technologies at home and abroad. The pump integrates self-priming and non clogging discharge, adopts a hybrid axial reflux, and passes through the pump body The design of the impeller flow channel can be similar to a general self-priming water pump, which does not require the installation of a bottom valve and inlet water, and can also suction and discharge large solid particles and long fiber impurities.
ZW unobstructed self-priming sewage pumpCompared with similar domestic products, it has the characteristics of simple structure, good self-priming performance (self-priming height can reach 5m), strong sewage discharge capacity, high efficiency and energy saving, and easy maintenance (can replace WQ and QW submersible sewage pumps).

Secondly:ZW unobstructed self-priming sewage pumpProduct Features

1. Strong overcurrent capability: The special impeller anti blocking design ensures high efficiency and no blockage of the pump;
2. Efficient and energy-saving: Adopting excellent hydraulic models, the efficiency is 3-5% higher than that of general self-priming pumps;
3. Good self-priming performance: The self-priming height is 1 meter higher than that of a typical self-priming pump, and the self-priming time is shorter than that of a regular self-priming pump.

4： Main uses of ZW self-priming sewage pump

ZW unobstructed self-priming sewage pumpIt is mainly suitable for transporting industrial wastewater and urban domestic sewage. Its advantage is that it has strong self-priming ability, and the suction pipeline does not require a bottom valve. It can transport sewage containing large solid particles, fiber materials, and various impurities, with a solid content of ≤ 35% and is not easily blocked. In addition to being suitable for transporting sewage, it is also used as a drainage pump, pulp pump, filtration, flushing, condensation and circulation pump, irrigation pump, etc. It is widely used in mining, construction sites, hospitals, hotels, sewage treatment and other occasions. Suitable for medium temperatures ranging from 0 to 150 ℃. This series of unobstructed sewage pumps is divided into two types: ordinary type and corrosion-resistant type. The ordinary type is made of cast iron HT200, while the corrosion-resistant type is made of 304, 316, 316L, etc. Different materials are used for different occasions.
