Operation away from BEP creates unbalanced hydraulic radial forces. The deflection of the shaft due to the radial forces creates a bending force that will occur twice per shaft revolution. For example, a shaft rotating at 3,550 revolutions per minute (rpm) will bend 7,100 times per minute. This bending dynamic creates a shaft tensile bending ...
Our vertical shaft centrifuges can be divided into three types: Série KM. Top unloading; Suitable for simple installation without opening the floor; Automatic Operation; Proven and best-selling model of top-discharge centrifuges; Simple and reliable operation, particularly suitable for small and medium-sized batches;
Pump bearings begin wear, allowing the shaft to move laterally, causing the shaft to flex and eventually fail. The vibration harmonics also puts extra stress on the pump shaft. Imbalance. Imbalance creates problems while the pump is running, though the shaft will measure straight if stopped.

Regardless of the alloy, your shaft needs a sacial anode. A collar anode attached directly to the shaft provides the answer. If your boat has a large anode on the transom connected to the bonding system, it will protect all bonded underwater metals. The shaft and propeller cannot be assumed to be bonded through the engine.
