Mechanical seal pumps

Mechanical seal centrifugal pumps are the right solution for applications involving solids in the liquid because their design with open impeller
allows to pump dirty liquids and fluids.
The seal in mechanical seal pumps is composed by a static ring and a rotating ring placed on the pump shaft which is directly coupled to the motor shaft. The two surfaces sliding together need to be lubricated and the seal lubricant is the liquid itself that is being pumped.
