Two Stage, Horizontally Split Case Pump

Two Stage, Horizontally Split Case Pumps designed for boiler feed, mine dewatering and other applications requiring moderately high heads with a wide range of service conditions • Capacities to 681 m3/h (3,000 GPM) • Heads to 305 m (1,000 feet) • Temperatures to 177°C (350°F) • Pressures to 3,792 kPa (550 PSIG) Design Features Casing Removal of upper half permits inspection, maintenance or removal of rotating element without disturbing piping or pump-to-motor alignment Impellers Hydraulically balanced - opposed for axial balance. Opposed cut-waters provide radial balance. Wear Rings Easily replaced,...

Performance Curve 3560 R.P.M. Except as noted. Specifications Shaft Short span keeps deflection to a minimum. Radius fillets are rolled into the shoulders at threaded portions to increase shaft fatigue strength. Radius fillets also machined into keyways to distribute stress more evenly along the shaft. Shaft Sleeve Threaded against impeller hub, and free to expand or contract with temperature changes. One sleeve tightens against rotation, and is further secured by a set screw. Other sleeve is key driven. This unique locking design of sleeves permits field change of rotation without additional parts....

HIGH THRUST CAPABILITY With duplex thrust bearing and shaft lock nut. Provides long, trouble-free operation under the wide service conditions to which these pumps are exposed. HEAVY DUTY SHAFT Designed for toughest services. Renewable shaft sleeves fully protect shaft from pumpage. HYDRAULICALLY BALANCED IMPELLERS Axial thrust of one impeller is counterbalanced by axial thrust of other impeller. Opposed cut-waters balance radial load reaction. Load on bearings is low. MAXIMUM PARTS INTERCHANGEABILITY Not only within the line but with Goulds Model 3405 single stage pumps. Keeps spare parts inventory...
