B. The baseplate must be cast iron drip rim baseplate with integral drip channels incorporated <br />on each side. Each channel shall include an NPT connection and plug. The baseplate must <br />conform to ANSI/ASME B73.IM 1984 Standard Dimensions and have pre -drilled holes for <br />pump and motor mounting as well as grout holes. The baseplate design must provide <br />sufficient rigidity to maintain alignment between pump and motor. <br />2.09 COUPLING <br />A. The shaft coupling between the motor shaft and the pump shaft is to be a flexible spacer <br />coupling, Falk T10 1090T. The coupling must have a drop out center spacer to allow the <br />shafts to be disconnected without disturbing the pump or motor. Coupling hubs are to be <br />keyed into position on both shafts. The flexible rubber insert is to be EPDM. The coupling <br />must be selected properly by horsepower rating and shaft size for the pump and motor <br />combination specified. <br />B. An OSHA approved coupling guard shall be furnished over the coupling for protection. <br />2.10 MOTORS <br />A. Drive motor shall be horizontal squirrel -cage induction type as specified in Section 16490. <br />The motor shall be for use with a VFD.
