Pulp & Paper Industry
Our gear reducers are as diversified as the industry itself supporting nearly every application in the pulp milling and paper manufacturing process.
What Your Operation Is Up Against
Unplanned Downtime
- Whether it’s due to bearing failures, gear tooth wear, lubrication breakdown, shaft misalignment and seal failures, every minute of downtime on a paper machine and supporting systems is expensive.
- Lost production worth thousands to tens of thousands of dollars per hour, missed customer deliveries, emergency maintenance labor, expedited replacement parts can add up to substantial revenue drain.
- Paper mills run 24/7 with very high loads and minimal shutdown opportunities. Many gearboxes are meant to operate continuously for years. When these units don’t perform as intended, reliability and sustainable revenue production is at risk.
Harsh Operating Conditions
- Pulp & Paper mills are one of the toughest industrial environments for mechanical power transmission equipment. From water spray and high humidity, chemicals, paper dust, wood fibers, and temperature swings, this industry is one of the most demanding.
- Maintenance teams spend significant time, energy, and revenue to maintain these critical gearing assets.
- Gearing is not the only area maintenance has to focus on. Expertise and resources are often stretched. Especially, with limited planned shutdown windows
Maintenance Costs & Long Lead Times
- Many mills still have reducers that are decades old, and are of multiple OEM brands. OEM replacement gearboxes can have lead times of 20–50+ weeks. Finding replacement parts, or quality rebuild options is time consuming and expensive.
- The need to stock costly spare reducers is further exasperated when it’s learned that what is on hand, or needs to be replaced, is obsolete, or is now a custom product. As technology advances, many tried and true gearing assets have been replaced by newer technology that no longer “drop in”.
- The efforts to locate and procure critical, now obsolete spares, cost time, potential equipment and production down time, and revenue drain.
