How to Properly Seat Mechanical Packing in a Pump Seal

Proper Packing Installation with the SealRyt Packing SeatingKit

Making sure your packing is installed correctly is key to keeping your pump seals working well and lasting longer. When packing is properly installed, it removes air gaps and helps the stuffing box, seal chamber, and rotating shaft function smoothly. This prevents mechanical problems and early wear.

In this post (and in the video below), we’ll explain why proper seating is important and how the SealRyt Packing Seating Kit can help you get the best results.

What is Seating and Why is it Important?

Seating the packing means pressing each ring firmly into place inside the stuffing box. This removes air gaps between the rings, the lantern ring, and the bottom of the seal chamber. If there are air pockets or spaces, it can weaken performance, wear down seal faces faster, and cause leaks. Poorly seated packing can lead to excessive leakage, weak shaft sealing, and a shorter sealing life.

Overview of the SealRyt PackingSeating Kit

The SealRyt Packing Seating Kit makes installing packing easier and more effective. It includes different seating pieces, color-coded by size, to fit various pump seals and shaft sizes. The kit helps compress each ring properly, reducing leakage drops per minute and improving sealing performance.

What’s in the Kit?

 The kit includes several packing pusher sizes to fit most stuffing boxes. All contained in a five-gallon storage bucket with a built-in seat on the lid for comfort.

 Included in kit:

Two Green 3/8” Pusher Strips*
Two Blue 1/2” Pusher Strips*
Two Yellow 5/8” Pusher Strips*
Two Black 3/4” Pusher Strips*
Two White 1” Pusher Strips*
*Packing Pushers come in one narrow and one wide widths.

How to Use the Packing SeatingKit

A Packing Seating Kit is imperative to install packing into a stuffing box correctly. Ensuring that each ring is fully seated is the first step to an effective seal. If packing is installed without seating, it can cause sleeve damage and reduce life-span. Seating allows the load to be evenly distributed over the entire ring set, thus creating a more adequate seal.
