Tyler Union Improves Safety and Efficiency with LOCK-TITE™ Liner System

Tyler Union is a ductile iron waterworks fitting foundry with a prestigious history spanning more than 100 years. As part of the global McWane Family of Companies, Tyler Union employs more than 500 people and is no stranger to innovation. They have kept their process and offerings current and competitive to remain a leader in ductile iron fittings for more than a century. 




The Challenge

Always looking to reduce downtime and improve safety for their team, Tyler Union saw their current rotary drum and liner system as needing improvement. Tyler Union began looking for drum liners that could be easily retrofitted to their relatively new drum, and later on, a solution that they could use to replace the rotary drum in another line. 


(Drum Liner History)

The prevailing solution in rotary drum liners are interlocking heavy metal liner pieces held together by pins. To install this style of liners, the pieces need to be carefully organized and stacked. Inserting the liners with forklift and boom, one at a time, and meshing the tiles together is tedious and potentially dangerous as overhead work can easily fall during installation, which places the maintenance team in harm’s way.  In addition, the construction of this commonly used liner proves challenging to modify or adjust when the process calls for it—often leading to lower efficiency and increased sand carryover. 



Familiar with General Kinematics through a history of vibratory equipment purchases, the team at Tyler Union talked about their rotary concerns with their GK representative. The General Kinematics team then shared an improved rotary drum liner design with Tyler Union. The GK liners promised drastically improved installation safety, less downtime, and a reduction of sand carryover. 

General Kinematics’ North American Foundry Director, Rick Kempf, recounts: “GK was engaged by Tyler Union, they had difficulty with installation, time to be down as well as the safety of the workers. General Kinematics was able to use their LOCK-TITE™ Liner System to improve their process, reduce downtime, and decrease overall maintenance cost.”

Tyler Union’s Vice President of Operations, Jon Pollard, on the history and relationship with General Kinematics: “GK supports Tyler Union by providing us with rugged equipment that can get the job done in a tough environment.”



After doing some research, the Tyler Union team decided to move forward with General Kinematics’ LOCK-TITE™ Rotary Drum Liner System. After a couple of modifications, Tyler Union has achieved great success with the liners and has since added a General Kinematics Rotary Drum and updated the liners once they reached the end of their service life.



Years after the installation of the first liner system, members of the General Kinematics sales team traveled to Anniston, Alabama, to interview the Tyler Union crew about their experience with GK products. The focus of the interview quickly shifted to the impact that the  LOCK-TITE™ Liner System has had on their operations. Starting from installation, the liners have made significant changes for the team, “The simplicity of the installation is so much better, and it gives us about another two days extra time to put them in. So it gives us a much shorter shutdown and time period.”, David Bannister, Tyler Union Maintenance Manager remarked about the liners.

In addition to an easy and fast installation, the GK liners are a simple cartridge design that slides into place and simply expands and locks, removing the possibility of falling pieces that could potentially harm workers. The Tyler Union team not only found installation to be an improvement but the actual efficiency of the unit was increased. Tyler Union Utilities Supervisor, Rodney Turner, “As long as the liners are doing what they’re doing, it returns the sand, because we reuse our sand over and over. Making sure that it does it properly saves us a lot of money on the cost of sand. Instead of having to put new sand in, it just keeps reusing it, keeps it clean, keeps the metal out of it, makes a better casting, makes a better process, a lot less maintenance.” Struggling with sand carryover in the past, the operation was able to see a huge improvement by reducing sand consumption and improving casting quality.

“Once we get it up and running in the morning, that’s one of the processes that I can depend on.”  Rodney continues, “You know, I don’t have to go back there and check it hour by hour and make sure something (is not) hung up or something broke loose. I know the liners are in there, I know it’s doing its job. It’s proved itself every day…It’s a quality product, does a good job, is dependable, and that’s one less thing that I have to worry about every day.” The liners and rotary drum are still installed and running smoothly. GK’s Rick Kempf on the success of this project, “One of the reasons that customers work with GK is because there’s a trust that’s built knowing that GK is going to provide the right solution.”.
