3409 Medium Capacity, Single Stage, Double Suction PumpsHeavy Duty Design Features for a Wide Range of Heavy Duty Industrial, Marine and Power Generation Services

HIGH THRUST CAPABILITY Spherical roller bearings handle unexpected thrusts. Secured withlocknut and washer.

RENEWABLE CASE WEAR RINGS Permits easy maintenance of properrunning clearances. Locked in lowerhalf casing to prevent rotation.

LARGE INLET AREAS Assures smooth flow toimpeller inlet for efficient,quiet operation.

HEAVY DUTY SHAFT Designed to reduce deflection. Renewable shaft sleeves fully protect shaft from pumpage. Threaded sections removed from stress areas.

LABYRINTH BEARING PROTECTION Labyrinth bearing isolators significantly reduce the chance for bearing contamination and greatly improve mean time between failures.

DOUBLE SUCTION IMPELLER Minimizes axial thrust. Highly efficient for smooth, vibration-free operation.

DUAL VOLUTE CASING DESIGN Dual volutes having cutwaters 180º apart provide opposing radial forces reducing radial loads on bearings and minimizing shaft deflection. Permits smooth, trouble-free operation over wide range of flow rates.

POSITIVE LIQUID SEALING Gaskets between impeller and sleeves, and O-rings between sleeves and sleeve nuts protect shaft from pumpage or confined corrosion attack.

RENEWABLE IMPELER WEAR RINGS AVAILABLE A must for proper maintenance of running clearances. Rings are mechanically locked onto impeller hubs.

HEAVY DUTY CASING Casing walls designed to withstand pressure extremes. Rugged design resists external forces and vibrations. Both suction and discharge connections in lower half casing. Removal of upper half casing permits inspection, maintenance and removal of the complete rotating element without disturbing piping or driver.
