John Crane C031-15 Mechanical Seal Type 88 For Pumps

John Crane C031-15 Mechanical Seal Type 88 for Pumps is a Type 88 seal designed for pump applications, with a 1.50" inside diameter. The part carries the identifiers C031-15, XF51, 05810581H, and C03115 for precise ordering and cross-reference. The 1.50" ID specifies the seal's inner bore, a key dimension used to match the seal to the associated pump shaft and housing in compatible systems. This configuration is identified by its C031-15 designation and is intended for use in pump installations that require a Type 88 mechanical seal in a 1.50" ID format. Using these exact identifiers helps ensure correct replacement and consistent sealing performance in maintenance and service operations.
