Overview of ZW explosion-proof self-priming sewage pump

ZW type self-priming sewage pump, also known as solid-liquid pump or impurity pump. The hydraulic design of this series of pumps is unique. The impeller is enclosed in a separate impeller chamber, which is connected to a pressurized water chamber. When the impeller rotates, the liquid inside the pump generates a strong axial vortex, creating a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressure chamber, so its flow channel is completely unobstructed, and its sewage discharge effect is unparalleled by other self-priming sewage pumps. The ZW self-priming vortex non clogging sewage pump produced by our unit does not require the installation of a bottom valve like a general self-priming clean water pump, and can also suck and discharge large solid particles, long fibers, sediments, waste mineral impurities, fecal treatment, and all engineering sewage materials. It can be widely applied to industries such as municipal sewage engineering, light industry, papermaking, textile, food, chemical industry, electric power, petroleum, mining, and river pond aquaculture. It is currently the ideal impurity pump for pumping solid particles, fibers, slurries, and mixed suspensions in China. Performance range Flow rate Q: 8-800 m3/h Caliber DN: 25-300mm Head H: 15-80m Speed N: 2900-1450r/min Motor power: 1.5-55kw

ZW type self-priming non clogging sewage pump is a pump developed by our company based on the structure and performance of ZX type self-priming centrifugal pump and QW type submersible sewage pump, and drawing on the advantages of similar foreign products, which integrates self-priming and sewage discharge. It can be used as a general self-priming pump for clean water without the need for a bottom valve or water injection. It can also suck up 60% of the large solid particles with an outlet diameter and 1.5 times the fiber length of the impeller diameter, including dirt, sediment, waste ore impurities, feces treatment, and all engineering wastewater and gelatinous liquids, completely reducing the labor intensity of human labor. Moreover, it is easy to install and use, with minimal maintenance, and its performance reaches the international advanced level. It has a broad application market and development prospects. All of our products are designed and optimized by computers, and our company has strong technical strength, rich production experience, and perfect testing methods to ensure the stability and reliability of product quality.

Suitable for industries such as chemical, petroleum, pharmaceutical, mining, papermaking, fiber, pulp, textile, food, power plants, municipal sewage engineering, public facility sewage, and river pond aquaculture.

Advantages of ZW explosion-proof self-priming sewage pump product

1. Strong sewage discharge capacity: The special impeller anti blocking design ensures that the pump is efficient and unobstructed.

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.

The significance of ZW explosion-proof self-priming sewage pump model

1. Before installation, carefully check whether there are any hard objects inside the pump body to avoid damaging the impeller and pump body during operation.

2. During installation, pipeline management should not be added to the pump to prevent deformation and affect normal operation.

3. Tighten the anchor bolts to prevent vibration during start-up from affecting the performance of the pump.

4. Install regulating valves on the inlet and outlet pipelines of the pump, and install pressure gauges near the pump outlet to control the pump's operation within rated conditions and ensure its normal use.
