ZDS Hi-pressure multilevel pump series have four kinds of self-balance structure: the sectional, the volute type double casing, the double casing type with drawout inner casing and rotor, and the horizontal split single casing, which take lead in domestic self-balance multistage centrifugal pumps area, widely used to transfer corrosive solutions in oilfield water injection, steelwork descaling, oil transfer, hi-pressure boiler feed, petrochemical product, and nuclear power plant. CPIC possesses a good reputation with the long-term operation of offered pumps in many steel corporations, ocean oil platform and petroleum chemical devices like Anshan Steel Corp., Wuhan Steel Corp., CNOOC, SINOPEC, etc.

Opposed arrangement of impellers can realize the self-balance of axial force and radial force, and non-contract spiral seal almost eliminates wear-and-tear parts. Those pumps have unique structure, high reliability and adaptability, in particular suitable for operating conditions which change frequently. Capacity: 120-600m³/h, pressure up to: 30 MPa
