A Pulp Mill Chooses DualPac® 2212 to Increase Their MTBF

Intro

Chesterton products – Chesterton DualPac® Packing Technology

Chesterton

A pulp mill was having issues maintaining their original packing solution under the high pressure from their fan pump. Lasting only six-to-nine months before needing replacement, they were experiencing high maintenance times and costs. Instead, they installed Chesterton DualPac® 2212, which is still needing little-to-no adjustments.

Challenge

A pulp mill in Canada was having some issues with their fan pump (30 x 36 DG). It was pumping water at a pressure of 4 – 6 bar, 885 rpm. The existing packing solution was lasting only six-to-nine months before needing a complete repack. The gland needed to be adjusted frequently and, in some cases, a partial ring replacement between repacks was necessary. The customer wanted to increase the MTBF and to reduce maintenance costs. The goal was 18 months desired running time before a repack.

Results

The customer installed the DualPac packing in June 2019 and was running at least six months without issues and with no need for gland adjustments. The customer is so impressed with the performance of the test packing set thus far that they have already ordered another set for one of their 14 x 16 pumps.
