The working performance and working environment of sanitary centrifugal pumps need to be further improved

The market prospect of sanitary centrifugal pumps is broad, but we still need to continue to improve working performance, increase reliability, and use diversified working environments.

Principle of sanitary centrifugal pump: Due to the special design of the pump casing. Its sealing performance is higher than that of ordinary centrifugal pumps, and the water in the pump casing will not be automatically emptied after the motor stops working. The motor drives the turbine to rotate at high speed, quickly forming a negative pressure (vacuum) in the pump. Use atmospheric pressure to press the water to the pump casing, and then centrifugal lift. Therefore, the suction range of the self-priming pump will not exceed one atmosphere, and the general suction range is within 3 to 7 meters. The sanitary centrifugal pump has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. The pipeline does not need to be installed with a bottom valve. Before working, it only needs to ensure that there is a quantitative lead liquid stored in the pump body. Therefore, the pipeline system is simplified and the working conditions are improved.

Sanitary centrifugal pumps are more effective as emergency pumps in industrial and agricultural production, emergency rescue, such as drainage and firefighting. They are widely used in urban water supply in industrial sectors such as petroleum, chemical industry, metallurgy, machinery, chemical fiber, food, energy, and transportation, and can also be used for agricultural irrigation and sprinkler irrigation. They are used to transport clean water or other liquids with a viscosity of less than 5°E and a temperature below 80℃ with physical and chemical properties similar to clean water. The products are widely used in fluid transportation due to their safety, reliability, and stable performance.

Sanitary centrifugal pump product features:

　　1. Single (double) flow impeller is adopted, with strong sewage discharge capacity, no blockage, and solid passing capacity is 60% of the caliber.

　　2. The tearing and crushing mechanism can tear and cut the fibrous materials, and then discharge them smoothly without adding a filter to the pump.

　　3. The use of titanium alloy mechanical seal can make the pump run safely and continuously for more than 8,000 hours.

　　4. Compact structure, easy to move, simple to install, no need to build a pump.

　　Compared with other types of centrifugal pumps, sanitary centrifugal pumps have the simplest structure because the pump itself has no check valve; they are the most reliable in operation; they have a long trouble-free working time, are easy to maintain and use, have a small size, light weight, high efficiency, and special considerations have been made in the design. Compared with pumps of the same caliber, they have a large displacement and high performance.

　　With the continuous development of economy, sanitary centrifugal pumps are more and more widely used in production engineering due to their strong sewage discharge capacity, high efficiency and energy saving, good self-priming performance, etc. They are not only suitable for urban environmental protection, construction, fire protection, chemical industry, pharmaceutical industry, dye printing and dyeing, brewing, electricity, electroplating, papermaking, petroleum, mining, equipment cooling, tanker unloading, etc. They are also suitable for clean water, seawater and medium with acidity and alkalinity, with viscosity less than or equal to 100 centipoise, solid content up to 30℅ or less, chemical medium liquid and slurry with general paste.
