C Series

Manufacturer: John Crane

Rigid Coupling with Radially Located Parts for Vertical Applications

C series rigid couplings incorporate a segmented, piloted locating design. This eliminates the shaft distortion associated with conventional‚¬Ëœclam shell' coupling designs where the motor shaft supports the pump shaft, and there are no bearings in the pump. It can also be used in vertical mixer applications, where the same characteristics are required.

Vertical rigid coupling designed to ISO 13709 (API 610) specifications, which has options of vertical adjustment and spacers. View animation showing this.
