Reverse Osmosis Diaphragm Plunger for Whirlpool WHER25

cults3d

My Whirlpool Reverse Osmosis system utilizes a plastic plunger designed for automatic shutdown. Years ago, I purchased a replacement plunger which ultimately failed (shattered into numerous fragments). This three-dimensionally printed replacement part has been functioning flawlessly in our system for over a year now. To print this part, use Food Grade PLA and sanitize it before installation. I employed RAPTOR Series Black PLA, which has FDA approval for contact with food products and prints at 245 degrees Fahrenheit. Depending on your printer (and whether the final component features seams or small projections), the part might require light sanding to ensure a perfect fit as the plunger must move freely for proper operation.
