Case Studies
Flushless Chesterton® 442 Split Seal and SpiralTrac® Environmental Controller Increase Run Time
Challenge
Background
The customer was using a double seal and tank to seal a booster pump on a dredge mining slurry application. The seal was failing after 3 to 6 months, requiring a full pump changeout and overhaul.
Pump was coming into the shop every 3 – 6 months with a failed seal.
Solution
Product
The customer replaced the double seal with a Chesterton 442 Single Split Seal and a SpiralTrac® Environmental Controller. The seal is designed to run without flush except for a quench on startup and shutdown.
Pump installed with a Chesterton® 442 Split Seal and a SpiralTrac® Environmental Controller.
Results
Less Downtime
The seal ran for nine months and was replaced only after an unrelated pump issue.
The split seal configuration is a cost savings and allows for quick changeout. Pump disassembly is not required.
The customer benefited from initial cost savings on seal the 442 vs the competition, longer seal life and run time, and minimal downtime to replace the seal.
The seal ran for 12 months.
