Maintenance
Peristaltic pumps are low-maintenance pumps. The pump tube is subject to chemical and
mechanical stress and wear.
If the pump does not reach the desired pump pressure even after replacing the tube, the rotor
has to be replaced.
CAUTION
Danger of death, electricity
►
Before opening the device housing, disconnect the power supply to the device and make sure it
cannot be switched back on.
CAUTION
Device is under pressure
►
Before disconnecting the tube, first depressurise the device to prevent chemicals from spraying.
►
Wear personal protective equipment in compliance with accident prevention regulations.
Important information
Each time that maintenance is carried out, check whether the work process in the
plant has changed.
If the work process has changed, the parameters on the device will need to be
adjusted to ensure correct operation again.
Replace the tube kit regularly!
The pump tube wears during operation, which reduces the flow rate.
If the tube kit with the pump tube is not replaced regularly, the tube will rupture.
