Pump motor with special flange
Published:  27 September, 2021

MENZEL ELEKTROMOTOREN says it has realised an unusual motor configuration to help out a customer: the operator of a large chemical plant needed a replacement for a failed pump motor. It seemed difficult, at first, to find a machine able to accommodate an existing oversized pump flange dimension.

Only the family-run company Menzel offered a size 400 motor that matched the performance profile and was light enough. The Berlin-based manufacturer converted a stock, IM B3 type motor (foot mounting) to type IM V1 (vertical flange mounting). For this purpose, the drive-end bearing seat was converted for the installation of a thrust bearing. Menzel also manufactured the special flange in-house and adapted it to the shaft, which could only protrude 120 mm from the flange.
