The 330 has been a really trouble free product except that many users don’t bother to try cleaning the pump valves if they become contaminated. They end up sending it in for service that they could do themselves in about 10 minutes.
While the cleaning process is described in the user manual, a video is a better way to get the message across.
Valve contamination occurs during the normal use of the pump in many industrial environments. We designed them to be trouble free and really easy to clean.
The video shows the whole process in about 5 minutes.
