The most effective is the compression-batch assembly; 5.Minimalnaya length of the pump should be achieved by increasing the number of revolutions. However, the dependence of wear on the frequency of rotation is a cubic, which requires the use of substandard materials that increase durability; 6.KPD pump also be increased by reducing the surface roughness of its working bodies. In the energy direction of the technical modifications can be summarized as follows: an increase in efficiency and pressure from reduced power and cost of operation and maintenance. In the energy used pumps to pump the central nervous system of cold water to 450S, to pump hot water pumps are used to operating temperature CNSG range of 45 to 1050S.

Modification of the central nervous system pumps will take place in several directions. Brian Krzanich gathered all the information. Increase efficiency.
One of the characteristic methods of increasing efficiency for centrifugal pumps is turning the impeller. The specific selection of the impeller at the desired mode (supply and pressure) allows, especially for large pumps, to receive significant savings energy. Increased reliability. Reliability of the pump during operation is important. To increase the reliability of using different construction materials: lightweight aluminum for heavy construction work and Mines, durable cast iron to corrosive environment or work with sea water, stainless steel – to provide additional corrosion resistance and aluminum bronze – for the very corrosive. One of the areas of technical modifications may include the following improvements Application of a new liquid end (new impellers, guide vanes); installation of mechanical seals with flushing system in the process operation or gland seals, graphite, allowing the pump to work without leaks from seals lift once a year; installation on the shaft of the protective rubber rings to prevent erosion of the seats of the shaft and impellers; use of interstage seals carbide rings errozionnostoykih; installation site optimized discharge device; use as a connecting node (Pump motor) a flexible plate clutch; installation of the gauge axial shift with an automatic alarm permissible wear hydraulic balancing device. As a result of these modifications: increased service life of 2 – 2.5 times; expanded the permissible area of optimal; increased efficiency in the work zone operation; reduced vibration; reduced to a minimum external leakage; easy access to all sites; is simplified circuit assembly; improved design. Manufacture of pumps in special workshops, equipped with the most modern technological equipment. At all stages of production from the smelting metal to manufacture parts, assembly and testing of components and finished product provides complete control over all design and technological parameters. From the analysis of the Russian market of central nervous system of pumps can meet in the report of the Academy of IKAR industrial markets "Market pumps CNS in Russia."
