Abstract

Centrifugal pumps are connected to their drivers through couplings of one sort or another, except for close-coupled units, in which the impeller is mounted on an extension of the driver shaft. Couplings are either rigid or flexible. The choice is determined by the bearing arrangement of the pump and driver combination. Rigid couplings permit neither radial nor axial relative motion between the driving and driven shafts, effectively making them a single shaft. Their use is therefore limited to pump and driver combinations with two or three bearings (Fig. 12.1 [a] and [b]). This category includes lineshaft-driven vertically suspended pumps, which are considered two-bearing machines with additional precision aligned guide bearings.
