The TracFOG is equipped with ceramic pistons to prevent abrasive wear. When properly used, these will provide long life.
One important consideration must be held. Avoid running the pump dry. When the pump runs dry, no liquid cools the pistons and they will heat up. If this occurs, DO NOT REWET the pump until these have cooled. Cool water entering the pump and contacting hot ceramic pistons will crack them. A common occurrence of this is that the valve above the solution filter is left closed after cleaning. The unit is readied for use, filled and started without opening this valve. The operator notices there is no fog and checks the unit, finding the valve closed and opens it. Cold solution water fills the pump, cracking the pistons. If this occurs, let the pump cool before opening the valve. __________________ Kurt Becker Dramm Corporation 920/645.6417
