October 2003 Goulds LP3400 Series Low Pulse Fan Pumps

Goulds Fa Standard Design Features for Reliable Low Pulse Headbox F RENEWABLE CASING WEAR RINGS Eliminate casing wear and permit easy maintenance of proper running clearances for maximum efficiency operation. Positively locked in place in the lower casing half to prevent rotation during pump operation. HEAVY DUTY SHAFTS Designed for minimum deflection in the toughest services means extended shaft seal and bearing life. Available as double ended shaft design as required, in either left-hand or right-hand rotation. DOUBLE SUCTION IMPELLER Minimizes axial thrust for longer bearing life. Dynamically...

an Pumps Feed Pumping LARGE INLET AREAS Reduce NPSH requirements and assure smooth, quiet flow to the impeller. Matched inlet and outlet connectors available as required. STUFFING BOX Packing is standard on LP3400 Fan Pumps. A wide variety of mechanical seals, including cartridge and split type, are also available to suit the application. RENEWABLE SHAFT SLEEVES Sleeves are sealed at the impeller and sleeve nuts to prevent liquid contact with the shaft extending life and reliability. Renewable shaft sleeves are available in a variety of materials (including hardened metals and hard metal coated)...

Goulds Fan Pumps in Modern Approach Systems Low Pressure Pulsations by Design Pressure pulsations are harmful to machine direction basis weight quality. Goulds fan pumps are designed for the rigorous tolerances of modern paper machine headboxes with tested pulsations measuring less than 1000 Pascals (0.0102 kilograms/cm2). 5

Goulds Low Pulse Pump Designs Low pulse pump operation is obtained through the exceptional design characteristics present in every fan pump manufactured by Goulds. Over the past 25 years we have perfected fan pump manufacturing using the following criteria for impeller manufacturing: • • Impeller casting are formed to a specific quality standard - equal vane passage volume - maintaining of vane angles, concentricity of inlet / outlet angles - maintaining of vane thickness Impeller machining has a strict tolerance quality - Surface symmetry and run-out is optimized - Balancing is dynamically performed...
