Key Features of the Product
Direct drive, saving space
Adopting a unique “inner shaft” design, the motor rotor is directly mounted on the oil pump shaft. Compared with the traditional motor+coupling structure, the axial installation length is shortened by about 1\/4, the structure is more compact, and equipment installation space is saved.
Silent and stable, maintenance free
Eliminating the alignment error of traditional connection methods, fundamentally solving the problems of high vibration and noise. The transmission efficiency is over 99%, running smoothly, effectively protecting the oil seal and preventing oil leakage.
High strength startup, overload optimization
Specially optimized for hydraulic pump operating conditions, with high starting torque, it can easily overcome the initial resistance of plunger pumps or gear pumps, and adapt to frequent starting and heavy load conditions.
Strong universality and easy installation
The flange interface and installation dimensions comply with international standards and can directly replace similar imported products. It is widely compatible with CB-B gear pumps, CY series plunger pumps, etc.
