Recommended service intervals
The design of the Alfa Laval Toftejorg SaniMxxxx 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 Alfa Laval Toftejorg SaniMxxxx 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.
A service 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. Look for wear of the bearings (A). Recommendation: Replace rotor if heavy wear on the bearing surfaces is observed.
5. Look for wear of the slots in the spray head. Recommendation: Replace rotor if slot width (slot at equator on rotor) exceeds
SaniMidget SB: 1.2 mm, SaniMagnum SB: 3.2 mm, SaniMega SB 4.2 mm and SaniMega SB high flow version 5.2 mm, as
throw length decreases and flow rate increases.
6. In case of machine wear, the parts worn down are to be replaced.
7. Reinstall machine.
8. Fill in the Service Log.
