Note: The model and parameters of the oil pump are provided by the customer, and the final confirmation is based on the supplier's drawing.

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.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.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.The bell housing is the connecting element between the IEC motor and the hydraulic pump. Customers can install our samples and choose the appropriate model. Of course, the quickest way is to provide the complete model of the motor and hydraulic pump, and Dongxu technicians will provide the exact model and drawings. The bell jars produced by our company have the following characteristics: 1. According to the international production, and to improve; 2. The whole piece and flanges at both ends are machined and can be connected to various hydraulic pumps of ISO installation size; 3. The motor shaft and the hydraulic pump shaft are automatically aligned, which is convenient, accurate and efficient to install; 4. The bell jar material is made of aluminum alloy, which is beautiful, light and rigid; 5. Can be used for heavy-duty connection; 6. With a large inventory, it is suitable for all kinds of hydraulic pumps.
