What kind of lubricating oil should be added to a centrifugal pump?

[DeMalia]

Centrifugal pump bearings are lubricated with LHV-46 lubricating oil or L-HV-32 lubricating oil. Below is the relevant introduction: 1. Principle: Centrifugal pumps work by using the rotation of the impeller to generate centrifugal motion in the water. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started to drive the pump shaft, impeller, and water in high-speed rotational motion, causing the water to undergo centrifugal motion and be thrown to the outer edge of the impeller, flowing into the pump's pressure pipeline through the volute-shaped pump casing. 2. Main function: The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.
