Dayton Mechanical Seal Seat Assembly PPR8ZN006G accessory

SKU CH-R3C7-Z5E8J

Mechanical seal and seat assembly compatible with multiple Dayton rotary gear pump models

  • Compatible with ten Dayton rotary gear pump models
  • Mechanical seal prevents fluid leakage under pressure
  • New condition guarantees reliable out-of-box operation

Compatible pump models

This mechanical seal and seat assembly is built for Dayton rotary gear pumps. It matches Grainger part numbers 4KHA9, 4KHC5, 4KHD1, 4KHD2, 4KHE2, 4KHE3, 4KHP4, 4KHP5, 4KHP8 and 4KHP9. Maintenance teams use it to restore sealing performance on those specific pump units. It is not for centrifugal, diaphragm or other pump designs.

Included components

The package supplies both the mechanical seal and the matching seat in one kit. Having the two mating faces together eliminates the risk of mixing worn and new surfaces. No separate gaskets, springs or hardware are mentioned in the data. Installers must reuse any existing fasteners or buy them separately.

Installation notes

The assembly drops into the pump seal chamber once the old faces are removed. Clean the housing bore and shaft sleeve thoroughly before fitting the new parts. A common issue is scoring on the sleeve that lets fluid bypass the fresh seal faces. Lubricate the elastomer with fluid compatible with the pumped medium to avoid dry start damage.
