High-pressure pumps CNS (BB4) in back-to-back design of high performance
JSC “Sumy plant“ Nasosenergomash ”has mastered new exclusive equipment – pumps of the CNS type with a capacity of over 400 m3 / h in a back-to-back design, without a hydropath assembly.
At the moment, the standard sizes of TsNSp 500 and TsNSp630 with heads up to 2000m have been successfully manufactured and tested
The mastered equipment has no analogues among the manufacturers of pumping equipment in the post-Soviet space
Constructive solutions developed by the scientific and technical center of the enterprise, and successfully applied components from leading European companies allow unloading the pump rotor from axial forces without the use of a traditional unloading device, hydraulic squeegee, which is exclusive for pumps of such standard sizes. Such a solution significantly increases the reliability of equipment, which is especially important for harsh operating conditions and for pumping corrosive liquids in such high-pressure systems as increasing reservoir pressure during oil production or knocking down scales at metallurgical plants.
