The new P2708X pump replaces the P2701, P2702, P2703, P2704, P2805, P2706, P2708, P2709, and P2710 pumps. The pump is equipped with a pressed on silicon carbide seal seat and a new shaft and bearing assembly is used with this change. Older pumps can be upgraded to this new design by utilizing the 25100-SHW shaft bearing assembly and the 25115-SHW seal kit. This seal kit includes a seal pusher that sets the proper height of the seal seat on the shaft.
For further information about this option and how to identify whether or not you have the seal upgrade, please follow the P2708X pump link and download the technical guide.
Warning: The new water seal kit 25115-SHW is designed to be used with newer pump designs P2708-01, P2708X, P2709-01, and P2710-01) or upgraded older pump designs using the new 25100-SHW shaft/bearing assembly that facilitates the new metal sleeve water seal. The 25115-SHW metal sleeve water seal cannot be used with the previous shaft and bearing assemblies. Doing so will cause damage to the shaft and the seal.
Identifying the proper shaft for use with the 25115-SHW mechanical seal kit: 25100-SHW shaft/bearing assemblies do NOT have a retaining ring groove on the shaft in the area between the impeller and the first bearing (the bearing on the impeller end of the pump). These shaft and bearing assemblies can be used with the 25115-SHW. If a retaining ring exists between the impeller and the first bearing, do not use the 25115-SHW mechanical seal kit.
