What is the function of mechanical seal in pump?
Mechanical seal in pump structure A mechanical seal is installed on the impeller rotating shaft. This prevents the liquid from leaking through the clearance between the pump body and the shaft. Mechanical seals are mostly comprised of two rings: a rotary ring on the shaft and a stationary ring on the pump housing.
