Abstract
A combination frame arranged between a centrifugal pump and a driver, such as a motor, the combination frame having in a central region thereof a compartment for holding shaft bearings and a quantity of oil, and a pump adapter frame arranged between said compartment and said pump, and a driver adapter frame arranged between said compartment and said driver, the pump and driver adapter frames and the compartment cast or forced as an integral structurally seamless frame between pump and driver. The driver adapter frame radially surrounds and covers impeller axial adjustment studs and reference nuts at the bearing housing, for protection. The combination frame of the present invention provides a stronger structural integrity than the multi-component frames of the prior art which allows for more precise alignment of the coupling between motor and pump which reduces vibration.
