The 805-343A drip cup is a simple but important component designed to collect and contain any fluid that may leak from the pump packing or seal area in compatible sprayer systems. It is specifically compatible with Impact 440 service; impact 640 I and IA; impact 640; and RentSpray 600 Impact models. In a piston pump, a small amount of fluid often seeps past the piston packing to lubricate the rod. This leakage is normal and is intended to be captured by the drip cup. The cup is typically mounted just below the packing nut and catches these drips, preventing them from running down the pump rod, onto other components, or onto the floor. This keeps the work area cleaner and protects other parts from constant fluid exposure. The drip cup is usually made of a clear or translucent plastic, allowing the operator to see the fluid level and monitor for excessive leakage. Over time, drip cups can become cracked, brittle, or broken. They can also become clogged. A missing or damaged drip cup will allow leakage to escape, creating a mess and potentially causing damage. Symptoms of a faulty drip cup include visible cracks, breakage, or the cup being completely missing. Replacing a worn or damaged drip cup with this genuine part restores its ability to contain normal packing leakage. This simple fix helps maintain a cleaner, safer work environment and protects the sprayer components. When installing, ensure the cup is securely attached and properly positioned to catch drips.
