Doser 2.2 pumps are largely maintenance-free. For optimal performance, we recommend occasionally cleaning and removing dust and other impurities from the inside of the pumps. The pumps must never be lubricated in any way!
Tubes, pumps and motors are wear parts, the life time depends on the use frequency, flow quantity and environmental conditions. When malfunctions (e.g. insufficient flow, losing prime, leakage, increased operation noise) or mechanical damages occur the wear parts must be replaced. Due to the maintenance-friendly design all wear parts can be replaced easily, all wear parts are available as accessories.
