The need to phase out a long-axis sub-liquid pump as a replacement for its application will be released
Self-suction pumps are pumps that use negative pressure to inhale liquids under certain conditions. Depending on the method of work, self-inhaled pumps are divided into gaseous blends (intra-mixed, extramixed), water rings, currents (water current, gas current) self-inspiration pumps。
The external hybrid self-suction pump is a commonly used self-suction pump, which is based on the storage of quantitative drawing fluids in the pump, the ability of the pump cavity to create a vacuum at the self-sorting height, the centrifugal power generated by the rotation of the pump wheel at the height of the pump, the discharge of the liquid from the outside, the formation of a vacuum in the negative pressure area at the centre of the wheel, and the transport of the liquid through the leaf rotation channel。
According to the report of china's special study on self-suction markets of 2025 and the enterprise's “fifty five-year plan”, published by the new thought industrial research centre, the self-suction function is the continuous inhaling, transport and discharge of liquids. It is structured, operational, smooth, adaptable, low-cost, easy to maintain, efficient, long-lived and well-regulated. It is widely applied in such areas as oil, chemical, pharmaceutical, mining, paper, textile, food, municipal sewage works, and river pond farming。
In recent years, increased demand for water treatment and treatment has led to the release of demand from the water lifting pump market as a result of industrialization, urbanization and population growth. Water lifting pumps usually have three types of submersible pumps, long-axis submersible pumps, self-suction pumps, which are better than long-axis submersible pumps in terms of operational stability, safety, etc., and are an alternative to long-axis submersible pumps。
Long-axis sub-pumps are used for transport of corrosive media such as particles, strong alkalin, strong acid, salts, strong oxidizers, high viscosity, but long-axis sub-axis pump bearings are susceptible to wear and tear, sealing out, causing the release of toxic material, or causing fire from flammable explosive media. In april 2025, the risk control division i division of the ministry of emergency management issued an opinion letter in which it was proposed that long-axis underwater pumps be included in the catalogue of technical equipment for the process to phase out the safe production of obsolete hazardous chemicals (third batch). As an alternative to long-axis sub-pumps, the application of self-sorting pumps will be wider as production safety requirements rise and long-axis sub-pumps withdraw。
Our country is a large producer and producer of self-smoking pumps, which are produced by zhejiang ishii pumping company limited, jiang soobo pumping company limited, jiangxi khadong pumping company limited, jiangsu shin light pumping company limited, etc. In the international market, self-suction suppliers include calpeda spa, italy, gorman-rupp, germany ksb, and bba pops, the netherlands。
New thought industry analysts have indicated that self-suction pumps have self-suction, drainage, liquid transport, etc., and that the application needs will be released further as long-axis sub-sort pumps are phased out as their replacement equipment. There are more participants in the self-suction market and the state-of-the-art self-suction performance of the national production has reached or is close to the international equivalent. With the upgrading of the industry, increasing the content and performance of self-suction technologies will remain the main direction for the future development of the enterprises concerned。
