PTFE Packing for Rotary Gear Pumps

This PTFE packing set contains three pieces designed for Dayton rotary gear pumps. It fits Grainger part numbers 4KHG5, 4KHH2, 4KHH8 and 4KHK2. Maintenance teams use it to restore seal integrity on compatible pump models.

Chemical Resistance and Temperature Tolerance

PTFE material handles aggressive fluids and a wide temperature range without degrading. The packing reduces leakage during normal operation and limits friction loss inside the pump housing. Power draw stays consistent because the seal maintains its shape under pressure.

Three-Piece Pack for Planned Maintenance

Each pack supplies three identical rings so technicians can replace a full set in one visit. The rings slide into the stuffing box without special tools and seat against the shaft with minimal adjustment. Compatibility with the listed Grainger numbers confirms correct fit for the target Dayton pumps.

Questions about this item

How do I install the PTFE packing into a Dayton rotary gear pump and which step is commonly missed?

Remove the old packing rings, clean the stuffing box thoroughly, then insert the three new PTFE rings one at a time, staggering the joints; the step often missed is lubricating each ring with compatible fluid before seating it.

What maintenance or replacement will the PTFE packing need over time?

Inspect the packing periodically for leakage or extrusion; replace all three rings as a set when compression no longer seals or the PTFE shows hardening or scoring.

What limit appears first when the pump runs continuously under pressure?

The PTFE packing will reach its temperature or pressure ceiling first, causing extrusion or loss of seal integrity before the pump housing or gears show wear.
