Slurry Pump Lantern Ring

The slurry pump lantern ring is typically installed in the bearing section of the slurry pump, located at the connection between the pump shaft and the pump casing. The lantern ring plays a crucial role in improving the performance of the slurry pump, reducing failures, and extending the equipment’s service life.

Sealing: Prevents liquid leakage, maintaining system integrity.
Cooling: Helps lubricate and cool the bearings, preventing overheating.
Wear Protection: Reduces wear on bearings caused by solid particles, extending service life.

Lantern Ring Installation Instructions

Alignment and Fixing: Ensure the lantern ring is correctly installed between the shaft sleeve and pump casing, avoiding misalignment. The lantern ring should fit properly with the mechanical seal and bearings to prevent loosening.
Sealing Check: The main function of the lantern ring is to provide lubrication and sealing. Ensure the sealing surface is smooth and undamaged during installation to prevent leakage. Before installation, check the fit between the lantern ring and the shaft, ensuring there are no impurities or debris.
Adequate Lubrication: The lantern ring requires good lubrication during operation. Check that the lubrication oil around the lantern ring is sufficient to ensure smooth operation and avoid overheating or excessive wear.
Material Selection: Choose an appropriate material for the lantern ring (such as a high-hardness alloy) to improve its wear resistance and adapt to the heavy-duty operation of slurry pumps.
