Description

Also known as hydraulic pump bell cover, pump sleeve. Usually in the hydraulic system, it is used to connect the oil pump and the electric motor.
One end of the flange is connected to the oil pump, and the other end is connected to the motor.
1. Used to connect IEC standard motors and hydraulic oil pumps;
2. The bottom of the bell-shaped cover is not solid but has ribs;
3. There are ventilation holes on the side to facilitate observation of the machine's operation;
4. It can be used for repetitive lot;
5. Available for the choice of vertical and horizontal motors.

Using advanced gravity heavy-duty casting equipment, casting aluminum alloy blank products, CNC machine tool equipment "car, drilling, tapping", processed into finished products.

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 bell housings motor and pump shaft are aligned to each other optimally.
Material aluminum low weight with sufficient strength.
Horizontal assembly possible with foot cum flange motor.
Bell housing material high graded aluminum pressure die cast.
Aluminum bell housing is precisely machined to reduce misalignment of coupled shafts.
Aluminum bell housing also reduces the noise generation considerably.
Aluminum bell housing size available as over factory stock.
