To ensure optimal performance of the VFD Compatible Deep Well Pump Motor, replace the lubricant (preferably ZL-3 lithium-based grease) every 5,000 hours of operation or if bearings overheat, filling to half the bearing space for 2-pole motors or two-thirds for 4/6/8-pole motors. Regularly monitor bearing vibration and noise, and promptly replace bearings if radial clearance exceeds standards, such as 0.3mm, to maintain reliable operation in demanding deep-well applications.
