✦ Synopsis

Both solid and hollow shafts are used, and electromotive forces are applied to rotate the shaft. Typically, a rotor is affixed to the outer circumference of the shaft (of either configuration) for this purpose, and the rotor is acted upon by a concentric stator. Either arrangement raises the possibility that some ofthe pumped fluid will leak from spaces between various stationary and rotating components. One way of eliminating the leakage problem is to used a 'canned' pump. In such pumps the rotor and shaft bearings are contained within a 'can' inside the 'pumpare' flow-stream. Although canned-pump designs are effective in addressing the leakage problem, they are inherently
