Mechanical seal MG12/18-G60 AQ1EGG k-t, Wilo (art. 2780194)

A single-stage centrifugal pump with a linear dry rotor, designed for installation in pipes or on a foundation. Block construction with low noise and vibration, with a lantern and a standard flange-mounted electric motor fixed (standard electric motor). With a sliding mechanical seal independent of the direction of rotation in a casing with forced cooling and a cavitation-reducing impeller. The flanges have fittings R 1/8 for pressure measurement.
A cataphoresis coating is applied to the pump housing and the intermediate housing.
