Mark 3 Recessed Impeller Pump

Pumps Flowserve

The Durco Mark 3 Recessed Impeller Pump is a Centrifugal Pump type with a recessed design and has a vortex action where only a fraction of the pumped media has physical contact with the impeller resulting in less abrasive wear but still maintaining solids integrity.

Thick-Wall Wet End Components offer extended service life in light slurry, corrosive/erosive services.

Mark 3A Power End with external micrometer impeller adjustment is precisely accurate and enables impeller clearance setting to rear cover in 20 seconds.

ANSI 3A Power End featuring Inpro VBX isolators comes with three-year performance guarantee.

Oversized Shaft and Bearing Components provide extended bearing life and reduced shaft deflection and vibration.
