Hidrostal Pump Repair Kits

Wemco Hidrostal 2 in. Pump Repair KitUpper & Lower Seals with O-Ring Set, Fits FEXW6-MYAK+XG1A31

Item #N/A

This Hidrostal pump repair kit is a direct-fit aftermarket seal set for the Wemco Hidrostal FEXW6-MYAK+XG1A31 screw centrifugal pump. Supplied with the 2 in. upper mechanical seal, the silicon carbide lower seal and the model-specific O-ring kit. Built to OEM-equivalent standards or higher.

What’s in the kit

Upper mechanical seal, 2 in. — Carbon / Ceramic / Nitrile, crimped head
Lower mechanical seal, 2 in. — Silicon Carbide / Silicon Carbide / Viton, rubber covered single spring
O-ring kit — cut for the FEXW6-MYAK+XG1A31

The lower seal is built above OEM

The original runs tungsten carbide against silicon carbide. This kit runs silicon carbide on both faces with Viton elastomers — the hardest pair we offer, on the seal that sits in the pumped media. Its single spring is rubber covered, so rag and stringy solids cannot wrap it.

Kit variations

Both options carry the same seals and the same O-ring kit. The only difference is whether the four power end bearings ship with them.

Kit	What’s in the box	Choose this if
Without Bearings	Upper seal, Carbon / Ceramic / Nitrile · Lower seal, Silicon Carbide / Silicon Carbide / Viton · FEXW6-MYAK+XG1A31 O-ring kit	You are resealing the wet end only, or the bearings were done at the last service and still run quiet.
With Bearing Set	Everything above, plus the four power end bearings: FAG 3317, Nachi 6310-2NSE9C3 and two Nachi 7311BMU	The pump is coming apart anyway. Doing seals and bearings in one shutdown saves a second teardown and a second freight charge.
