CAUTION
●Be sure to pour oil.
●If the oil level becomes lower than the lower limit during the
operation, the bearings, gears, shaft seals, etc. are damaged,
causing leakage, abnormal noise, overloaded motors, or a
shutdown.
3.6.2 Lubrication to the mechanical seal
There is a mechanical seal inside the cover on the pulley side. If you supply lubricant to the cover
on the pulley side, the mechanical seal is also lubricated.
In order to prevent the oil shortage of the mechanical seal, when operating the pump after stopping
the pump for more than 3 months or after having relocated the pump, be sure to lubricate to the
mechanical seal.
Lubricate 500ml or so by providing oil again after once discharging the inside oil.
