Convention capacity and dosage:

The dosing capacity ranges from 8 to 45 ml per minute, accurately adjustable to 0.1 ml. The Dose 2.1 pumps are largely maintenance-free. For optimal performance, it is advisable to clean and remove dust and other impurities from the inside of the pumps periodically.

Please note that the pumps must not be lubricated in any way!

Keep in mind that tubes, pumps, and motors are wearing parts, and their lifespan depends on usage frequency, power quantity, and environmental conditions. In case of defects such as insufficient flow, loss of filling power, leakage, or increased operating noise, or if there is mechanical damage, the wear parts must be replaced. Thanks to the maintenance-friendly design, all wear parts can be easily replaced, and they are available as accessories.
