Open impellers are seal chambers with flow modifiers extend seal life and provide self-flushing micrometer accurately sets impeller clearance in 20 seconds, whether in the shop or in the shaft and bearing components in standard asme Pumps reduce shaft deflection and vibration to extend bearing life and improve pullout design allows removal of rotating element without removing casing, piping or Mark 3 asme Chemical Process pumpsConforming to asme ( ansi ) and incorporating many advanced design features, the rugged Mark 3 pump provides unmatched performance and reliability while minimizing the total cost of ownership.

4 It is CE marked and compliant with applicable directives such as Higher flow rates are available with the Ducro Mark 3 Group 4 high-capacity Process pump. See brochure PS-10-39 for Mark 3 asme ( ansi ) Chemical Process Pump 5 Reverse vane impeller lowers total cost of pump ownershipThe Durco Mark 3 pump features a reverse vane impeller for unequaled efficiency and performance. This exclusive Durco design lowers pump ownership cost by easing maintenance and extending bearing and seal life. Low, predictable seal chamber pressure and thrust loads Lowest NPSHR of any asme standard pump Abrasive wear is on the rear machinable cover, rather than the more expensive casing In-shop impeller adjustment with the only impeller that takes full advantage of the back pullout design Repeatable performance assurance Truest running asme ( ansi ) pump The Durco Mark 3 pump is engineered with four precision-machined, metal-to-metal fits to improve reliability.

5 Reduce tolerance stack-ups on bearing carrier to improve shaft concentricity Superior to jackscrew designs, which can cause cocking Extend bearing and mechanical seal working lifeSealSentry seal chamber technology helps the bottom lineThe Durco Mark 3 incorporates SealSentry seal chambers with flow modifiers (FM) that reduce pump operating costs and increase pump availability by: Improving mechanical seal performance, reliability and life Reducing maintenance and repair costs Enabling the use of less costly seals and flush plansTypical applications Acid transfer Caustic and chlor-alkali Man-made fibers Polymers Slurry processing Solvents Volatile organic compounds Waste processing6 Performance curves2m806040200ft300250200150100500 TDH 1750 RPM (60 Hz)ft200150100500m6050403020100 TDH 1450 RPM (50 Hz) 0 200 400 600 800 1000 2800 4600 6400 8200 gpm 0 50 100 150 200 227 400 800 1200 1600 2000 m3/h3 FLOW 1750 RPM (60 Hz)

Superior to jackscrews, it accurately sets reverse vane impeller clearance in 20 seconds, in the shop or the 1: Loosen the setscrews. Using a wrench, rotate the bearing carrier counterclockwise until the reverse vane impeller lightly touches the rear cover plate. Step 2: Select the impeller setting. Each notch on the carrier ring represents exactly mm ( in) of clearance. For an impeller setting of mm ( in), count five notches 3: Move the carrier clockwise the selected number of notches. Tighten the setscrews and check the impeller clearance with the feeler micrometer10 Shafts and bearings 5 shaft and sleeve optionsDurco Mark 3 shafts and sleeves are designed to improve pump reliability and performance.
