Protect the Pump. Protect Production.
Your filter is designed to catch contaminants, but only after material passes through the pump.
Tank → Pump → Filter → Hose → Gun → Nozzle
Keep the lid closed and foreign objects out. A clogged filter is maintenance. A damaged pump is downtime.
A clean tank today prevents costly repairs tomorrow.
Keep Your Tank Clean: Protect Your Pump and Your Production Line
Keeping your hot melt tank free of debris and foreign objects is critical to the performance and longevity of your equipment.
A common misconception is that the filter will catch any contaminants that enter the tank. The adhesive must first pass through the pump before reaching the filter. The pump is responsible for generating the pressure needed to move the adhesive through the system, meaning any debris inside the tank is pulled through the pump first.
Because of this, foreign objects can cause significant damage to pistons, gears, seals, and other pump components before ever reaching the filter.
While a clogged filter can typically be replaced quickly and inexpensively, a damaged pump can result in:
🔹Increased repair costs
🔹Replacement parts expenses
🔹Additional labor
🔹Unplanned production downtime
🔹Reduced equipment reliability
The lid on your hot melt unit serves the same purpose as the gas cap on your vehicle. Keeping the lid closed helps prevent dirt, dust, metal shavings, packaging scraps, and other contaminants from entering the system.
By ensuring only adhesive is added to the tank, you can:
🔹Reduce unexpected downtime
🔹Protect pumps and other critical components
🔹Extend filter life
🔹Improve adhesive flow and application quality
🔹Increase equipment efficiency
🔹Lengthen preventative maintenance intervals
Your filter should be focused on capturing char and microscopic contaminants, not preventable foreign objects that enter through an open tank.
Adhesive Flow Path
Tank → Pump → Filter → Heated Hose → Applicator/Gun → Nozzle
