N.B.:
- The numbers listed in the table indicate the relevant baseplate numbers.
- The baseplate numbers shown in the boxes also serve to select the correct motor size for the listed pump size.
- Units comprising a motor size 315 and larger are completely assembled for verification and adjustment of the individual
components. Before shipment, the units are dismantled again and the components packed / shipped separately.
