Mark 3 Unitized Self Priming Pump

(Go to page 28 on pdf for details on the Mark 3 Unitized Self Priming Pump)

The Durco Mark 3 Unitized Self Priming Pump is a Centrifugal Pump engineered to draw from liquid sources below ground level or from sources which have no positive pressure to naturally prime the pump. Conveniently located high and dry at ground level where an installation is simple and maintenance is easily and more economically performed, the Mark 3 Self-Priming pump costs less to buy, install and maintain than submersible pumps. The Mark 3 Self-Priming pump’s compact design enables it to fit in tight clearance locations. It also can be mounted on a trailer for movement to various pumping areas, such as for wastewater lagoon service.

Applications:
Hydrocarbon Processing, Polymers, Petrochemical Processing, Slurries, Solvents, Sump Service, Water Treatment, Acid Transfer, Aquariums, Chemical Processing, Chlor-alkali, General Purpose, General Processing Industry, Tank Car Unloading.

Industries:
Desalination, Water Treatment, Wastewater Collection and Treatment, Snowmaking, Ground Water Development and Irrigation, Water Supply and Distribution

Unitized Casing has large priming chamber, air separator and volute in one integral piece.

Exclusive Reverse Vane Impeller is the only impeller design that offers repeatable pump performance throughout the life of the pump.

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 a three-year performance guarantee.

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