Maintenance and Repair
In order to keep the tank cleaning machine servicing as an efficient tool in the tank cleaning operations,
it is essential to maintain its high performance by following a simple preventive maintenance
programme, which will help keep the tank cleaning machine in good condition.
Good maintenance is careful and regular attention!
Recommended Service Intervals
The design of the SaniMidget SB asks for little maintenance, as there are no rotating parts in direct
contact with stationary parts. It is recommended that inspection is performed after each 500 running
hours.
For continuous surveillance of the SaniMidget SB, monitor and log the volumetric flow rate. If the
volumetric flow rate increases or decreases by more than 15% over time this could be a sign of wear or
blockage of the flow path in certain parts of the machine and the machine should be inspected.
An inspection consists of:
0. At a pressure of 0.3 bar open a hatch in the tank to verify rotation and liquid fans are emerging
from all slots.
ATTENTION: Use only pure water at normal temperature for safety reasons.
If needed proceed to 1).
1. Un-install the machine (as described on the following pages)
2. Visual inspection for foreign objects. Remove any objects and clean before rotation verification.
3. Visual inspect the bearing surfaces, the holes for the clip-on connection and the width of the slots
in the rotor.
4. In case of machine wear, the parts worn down are to be replaced.
5. Look for wear of the slots in the spray head. Recommendation: Replace rotor if slot width exceeds
1.5 mm, as throw length decreases and flow rate increases.
6. Reinstall machine
7. Fill in the Service Log

Service and Repair of Machines Ordered with Alfa Laval Q-doc
In order to ensure full traceability and to obtain full test documentation (FAT: Factory Acceptance
Test), it is necessary to order a new Rotary Spray Head machine with Alfa Laval Q-doc. The new
Rotary Spray Head machine will be manufactured and tested (FAT) and shipped to the customer with
new Alfa Laval Q-doc for further qualification (SAT: Site Acceptance Test) and validation (PV: Process
Validation).
