1) Supply and demand of water pump market
Water pumps are widely used general machinery products. Our pump products have about 450 series and more than 5000 specifications, which are widely used in agriculture and water conservancy, construction industry, petroleum industry, power industry, shipbuilding industry, mining, metallurgical industry, environmental protection and other industries. . In recent years, with the rapid growth of the domestic economy, the market demand for pump products has also grown rapidly. According to statistics from the Institute of Industrial Pumps of Zhejiang University of Technology, my country's pump industry achieved sales revenue of more than 100 billion yuan in 2009, and the industry's industrial output value was around 108 billion yuan, and production and sales were basically balanced. The regional distribution of industrial output value is: 26 billion yuan in Wenling area of Taizhou, 10 billion yuan in Wenzhou Yongjia area, 5 billion yuan in Hangzhou area, 15 billion yuan in Shanghai area, 6 billion yuan in Shandong area, 8 billion yuan in Shenyang area, Dalian area 6 billion yuan, 5 billion yuan in Guangzhou area, 3 billion yuan in Beijing Tianjin area, 2.5 billion yuan in Shijiazhuang area, and Changsha area25. In recent years, the pump industry has maintained a rapid growth momentum. The growth rate in 2007 was 23.20%. Due to the impact of the economic crisis, the industry growth rate in 2008 fell back to 13.5%. With the rapid development of the scale of the pump industry and the intensification of market competition, the growth rate of the pump industry will stabilize. It is estimated that the industry will develop at a speed of 13%-17% in the next five years. Quality improvement and transformation.
(2) The supply and demand situation of the stainless steel water pump market segment
A. Demand situation of stainless steel water pump market segment
Stainless steel water pumps are mainly used in several fields such as water purification, building water supply, air conditioning water circulation, industrial cleaning, medium and low pressure boiler feed pumps, deep well water pumping, pharmaceuticals and food. The market demand is very broad. According to the statistics of Zhejiang Science and Technology Consulting Center According to the data, the demand status of the main application areas of stainless steel sanitary pumps is as follows:
a. Water purification treatment field
From the late 1990s to the beginning of this century, the domestic water purification industry characterized by membrane treatment technology developed rapidly, from the electronics industry and the pharmaceutical industry to the food industry, power industry, textile industry, refrigeration and air conditioning, and domestic drinking water purification. Most of them use stamping and welding structure stainless steel stamping and welding centrifugal pumps. So far, the application of punching and welding pumps in the domestic water purification market is still very huge. According to the project feasibility study report issued by Zhejiang Science and Technology Consulting Center, the domestic market for water purification technology pumps is about 300,000 units per year.
b. Building water supply field
Existing pumps for water supply systems in the construction industry are mostly cast pumps, which are difficult to avoid secondary pollution and cannot meet the requirements of purifying water supply. With the vigorous promotion of new technologies and products for energy saving, water saving, material saving, land saving, sanitation and environmental protection, as well as increased awareness of preventing secondary pollution of water quality and ensuring drinking water safety, in the new building design, its life, production and fire fighting water supply In the secondary water supply field of the system, stamping and welding stainless steel stamping and welding centrifugal pumps have begun to replace the existing casting pumps on a large scale. According to the project feasibility study report issued by the Zhejiang Science and Technology Consulting Center, the water supply system of the construction market is about 500,000 units of various types of water supply pumps, fire pumps, and stabilized pumps used in the construction and renovation each year.
c. Air conditioning water cycle field
With the improvement of domestic residents' living standards and environmental protection awareness, the market demand for water-cooled central air-conditioning and heating systems has grown rapidly. Central air-conditioning systems and heating systems have relatively high requirements for circulating pumps, requiring high efficiency, no leakage, good reliability, and low noise. Therefore, the domestic high-end central air conditioners used imported circulating pump products. Most domestic air-conditioning and heating systems have circulating pumps. Use cast centrifugal pump. With the development of my country's stamping and welding centrifugal pump industry, domestic stamping and welding centrifugal pumps have gradually replaced cast centrifugal pumps and adopted by central air conditioning systems and heating systems. The domestic air-conditioning and heating industry needs more than 300,000 circulating pumps per year.
d. Industrial cleaning field
Industrial cleaning is widely used in the electronics industry, mainly for cleaning circuit printed boards. Various organic cleaning agents are often added to the cleaning fluid, so the cleaning pump is required to be rust-free, high-pressure, resistant to light corrosion, and have a small flow rate. Cast iron pumps cannot meet their requirements. Plunger positive displacement pumps are often used in China, but there are problems such as high cost and difficult maintenance. The punch-welded multi-stage centrifugal pump just meets the needs of the cleaning industry. Compared with the plunger positive displacement pump, it has a higher cost performance, so the current use rate is increasing year by year.
e. The field of medium and low pressure boiler feed water
Medium and low pressure boiler feedwater pumps used to be casted horizontal multistage centrifugal pumps, which not only occupy a large area, but also have low reliability and difficult maintenance. With the popularization and use of vertical light multistage pumps, medium and low pressure boiler feedwater pumps are gradually Replaced by stainless steel multi-stage pumps. The industry uses about 80,000 pumps every year.
f. Deep well water lifting field
At present, more than 90% of foreign multi-stage submersible pumps with a diameter of 250 mm and below are stamped and welded. The use of stamped and welded structures can make the outer diameter of the pump smaller and more compact, and greatly reduce the cost of drilling wells. . With the improvement of domestic residents' living standards, the sales of stainless steel submersible pumps in the domestic submersible electric pump market have increased year by year.
g. Pharmaceutical industry and food industry
The annual demand for pumps for pharmaceuticals and fine chemicals is about 10,000, and the annual demand for pumps for food and beverages is about 30,000. In addition, stainless steel stamped centrifugal pumps will gradually replace small and medium-sized pumps used in the fields of rural water supply, drainage, urban and rural domestic water transportation, industrial and mining and construction site water supply. According to "Summary of my country's Pump Industry Market Development" (China Construction Information (Water Industry) Market), 2009 (10th issue) data show that the annual demand for pumps in the above-mentioned fields reached 12 million-15 million units. This demand includes the demand for stainless steel stamping and welding centrifugal pumps. In summary, the market demand for stainless steel stamping centrifugal pumps is large and the development prospects are broad.
B. Market scale of stainless steel stamping centrifugal pump market segment
According to the "Analysis Report on the Status and Development Prospects of the Stainless Steel Pump Industry" compiled by the Industrial Pump Institute of Zhejiang University of Technology, in 2018, the sales of the foreign stainless steel pump market were between 18 billion and 20 billion, and the domestic market sales were around 3 billion. In the next 3-5 years, the sales of stainless steel water pump market is expected to grow at a rate of 20-25%, which is higher than the average growth rate of the pump industry.
