Q. When purchasing vertical turbine pumps, can the motors be purchased directly from a motor supplier?
A. Vertical pump motors are normally supplied with a registered (rabbet) fit mounting base conforming to industry standard dimensions and drilling. It is customary for the vertical pump manufacturer to supply the motor to ensure:
