Mechanical seal centrifugal pumps represent the ideal solution for applications where the pumped liquid contains solids or suspended particles. Thanks to their design with an open impeller, they are suitable for handling dirty fluids and contaminated liquids.

In this type of pump, the mechanical seal assembly consists of a stationary ring and a rotating ring mounted on the pump shaft, which is directly coupled to the motor shaft. The two sealing faces slide against each other and require continuous lubrication. The pumped liquid itself acts as the lubricant, ensuring proper sealing and correct operation during service.
