Pro Tips for Maximizing Service Life of Your 490 XT Lo-Boy Pump
Want more uptime and less maintenance? Here are field-proven tips to help extend the life of your pump:
Document Service Intervals
Track spray hours, flush intervals, and filter changes. Preventative maintenance reduces blowouts and spray pattern inconsistencies.
Always Pair New Seal Kits with Fresh Lubricant
Elastomers rely on proper lubrication. Dry installs or reusing old lube shortens kit life.
Keep Spare Wear Items in Stock
Stock essential wear parts like packings, filters, and o-rings. On multi-day jobs, this can save hours of downtime.
