While pump developing and manufacturing the original constructive solutions have been used. It makes possible to increase the quality, reliability and operating life of the pumps. In order to increase the coefficient of efficiency the pumps are manufactured with I and II rotors and M, a, b, v, g working wheel grooving.
Performance according to the material of flow part:
С – carbonic steel ASTM A216WCB, A352LCB
Х – chromic steel ASTM A217CS, AiSi420
Н – chromium-nickel steel UNS J92630, J92701
