Seat Retainer for Rotary Gear Pumps

This Dayton seat retainer is a direct replacement component for rotary gear pumps used in fluid-transfer systems. It is designed for maintenance technicians and plant engineers who need to restore sealing performance on compatible Dayton pump models.

Replaces worn or damaged retainers

The part replaces an existing seat retainer that has degraded through normal service, eliminating the leak path that develops when the seating surface erodes. The upgrade is worth it when a pump shows reduced pressure or visible weeping at the seal, allowing the unit to return to full rated flow without a complete pump change.

Fits Dayton pumps using Grainger numbers 4KHF6

The retainer installs into the pump housing with standard hand tools and requires no modification to the surrounding pipework. It frees up maintenance time by avoiding a full pump teardown and keeps the original drive and mounting configuration intact.

Questions about this item

Which Dayton rotary gear pump models accept the PPM5ZN007G seat retainer?

This seat retainer fits Dayton rotary gear pumps that correspond to Grainger part numbers 4KHF6 and 4KHF7.

What is the correct orientation when seating the PPM5ZN007G retainer in the pump housing?

Align the retainer so its machined face sits flush against the pump body shoulder; reversing it leaves a gap that causes bypass leakage.

How often should the PPM5ZN007G seat retainer be inspected or replaced in normal service?

Inspect the retainer during each scheduled pump overhaul; replace it if the sealing surface shows scoring, pitting or measurable wear.
