Description

1. It is used to connect IEC standard motor and hydraulic oil pump;
2. The bottom of the bell hood is not solid but has reinforcing ribs;
3. There are ventilation holes on the side, which is convenient to observe the operation of the machine;
4. Can be used for repeated loads;
5. The choice of vertical and horizontal motors is available.

Function

This installation method can minimize the coaxiality error of the two shafts, and make the oil pump rotate without noise, which is an ideal way to prolong the service life of the oil pump.

Features

No air holes,  strong tensile strength, large torque, high density (+T6)

By using the bell-shaped housings, the motor and pump shaft are optimally aligned to each other.
Aluminum material is light in weight and high in strength.
Horizontal assembly may be combined with foot flange motor.
Bell-shaped shell material is advanced aluminum die casting.
The aluminum bell-shaped shell is precisely processed to reduce the dislocation of the coupling shafts.
The bell-shaped aluminum shell also greatly reduces noise.
The size of the aluminum bell-shaped shell can be regarded as exceeding the factory inventory.
