CKV are vertically-suspended, single or multi-stage centrifugal pumps (VS4 configuration). Bowls are integrally cast diffuser type to assure optimum hydraulic efficiency and minimum radial thrust. A generously sized, carefully designed line shaft assures rotor stability and low vibration level.Rotor axial positioning and support is granted through an oil lubricated double row ball thrust bearing. A rigid coupling with spacer allows the removal of the cartridge mechanical seal without interfering with motor positioning and alignment.Line shaft bearings are normally lubricated by the same pumped fluid and can be provided in different material combinations, depending on the fluid to be handled.
