Bell housing with centre ring - IEC 100-112 - Gr. 3

The 4E type bell housing is equipped with a centre ring allowing removal of half-coupling (which as a rule is keyed permanently to pump shaft). The motor mounting flange drilled with 4 clearance holes + 4 threaded holes.

Normally used for motor and pump units mounted horizontally on the tank lid on the machine for maximum ease of maintenance.

With this type of mouniting, in effect, the hydraulic pump can be removed without removing the motor.

The half-coupling mounted to the shaft passes through the spigot hole.
