ZW horizontal sewage self-priming pump is an efficient, energy-saving, and non clogging sewage pump developed by combining advanced technology of similar products at home and abroad. Its performance indicators have reached the technical level of similar foreign products. Due to the use of a unique open impeller and a special hard alloy material for the mechanical seal dynamic and static rings, the entire sealing system fully references foreign technology. It has the characteristics of non clogging, long sealing life, easy maintenance, and high efficiency, and is highly welcomed by users. Purpose ZW horizontal sewage self-priming pump 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 A3 material, while the corrosion-resistant type is made of 304, 316, 316L, etc. Different materials are used for different occasions. Model Description Example: ZW100-100-20
Z - self-priming
W - Sewage and Waste Series Pump
100- Pump inlet diameter (mm)
100- Rated flow rate (m3/h)
20- Rated head (m) Introduction to the structure of ZW horizontal sewage self-priming pump ZW horizontal sewage self-priming pump is made of carbon steel, stainless steel, and can be equipped with an explosion-proof motor to meet the different requirements of users. The structure consists of two parts: the motor and the water pump.
1. The motor adopts asynchronous motor, and can choose variable frequency or explosion-proof motor.
2. In the pump section, the water pump is located at the other end of the motor. The impeller of the water pump is open, with strong drainage force and is not easily blocked. It pumps polluted liquid containing fiber substances and suspended solid particles impurities. The sealing technology is advanced and the service life is long. Technical performance indicators
