Conver- accomplished in the field without machining. Equalizing piping keeps boxes at essentially suction pressure. Limits stuffing box pressure. Protects casing from wear. Easily replaceable....

Performance Curve Model 3316 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 Sleeves 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. An O-ring seal positively...
