Mechanical seal assembly: in the moving and static ring mirror coated with a layer of clean 20 lubricating oil; Guide bearing seat with lubricating oil, the static ring gently positioned into the guide bearing seat; Then grease the pump shaft, gently load the moving ring part of the mechanical seal

Disassemble the split coupling: first unscrew the hex screw fixing the coupling, and then gently pull half of the coupling from the shaft slowly (be careful not to fall off). Unscrew the pump shaft retaining bolt and block with the box wrench, let the impeller slowly sink to the pump body, remove th

Mechanical seal is very important for chemical pump, hot water pipeline pump, oil pump. The installation of mechanical seal can make the pump run without leakage, greatly improve the working environment of the pump management personnel, but also extend the service life of the pump.
