Quality and Functionality. Down to the Smallest Detail.
Each pump can be operated manually via the push buttons on the front panel. This allows you to quickly post-dosing, deflating the tube vent or suctioning liquids.
Maintenance & wear parts
The pumps are largely maintenance-free. For optimal performance, we recommend occasionally cleaning and removing dust and other impurities from the inside of the pumps. In order to reduce noise during operation it is allowed to lubricate the pump with vaseline.
Tubes, pumps and motors are wear parts, the life time depends on the use frequency, flow quantity and environmental conditions.
Average lifetime: 5000 hours for the motor, 800 hours for the pump head.
When malfunctions (e.g. insufficient flow, losing prime, leakage, increased operation noise) or mechanical damages occur the pump head or motor must be replaced. Due to the maintenance-friendly design wear parts can be replaced easily, wear parts are available as accessories.
