Franklin used to use the HP rating of the pump end in the part number for SubDrives. They now use the HP of the motor in the part number of the SubDrives. So your question is does the SubDrive 150 which is for a 1-1/2HP pump end and 3HP motor is now the SubDrive 30. A SubDrive 50 would also work but can handle up to 3PH 5HP motors also. The SubDrive 30 is also a NEMA 3R which can replace both SubDrive 150 NEMA1 and NEMA4 models. The new SubDrives can use either a pressure switch or a transducer for pressure control. Bottom line is yes the SubDrive 50 will directly replace the SubDrive 150 but you could also choose to reduce your cost by using the SubDrive 30. David Slagle

Yes, it would be more rugged for smaller motors. Its all about the heat it generates while doing its work, smaller motor - less heat. The specs do contain the motors compatible with the SubDrive 50. It is a kit containing all hardware needed for operation. The newest SubDrive's have the ability to use either a transducer or pressure switch supplied by Franklin.
