10. Lubrication and Maintenance of the MQM Quantometer
1.
Quantometers with permanent lubricated ball bearings (no oil pump) are maintenance-free.
2.
Quantometers with an oil pump need periodic lubrication.
The initial lubrication procedure is:
a.
Use only oil recommended and supplied by Metreg Technologies.
One set of oil for commissioning is delivered with the meter.
b.
Specified oil: Shell Morlina S2 BL 5 or Shell Morlina S2 BL 10
c.
Fill in the oil before commissioning the meter and after the correct
installation of the meter described in chapter 7 and 8.
d.
Fill an adequate quantity of oil in the supply tank, and then horizontally
pull the hand lever dependent on the size of the meter:
DN 50: 3 strokes
DN 80: 5 strokes
DN 100: 5 strokes
DN 150: 9 strokes
e.
When the lubrication procedure is finished, close the cover of the supply tank
to avoid any dirt or impurities to enter the lubrication system.
