The CBJ30-F series gear pumps are widely used in various agricultural machinery—including tractors, harvesters, and rice transplanters—as hydraulic system working pumps.
CBJ Series gear pumps are available in single, double, and triple configurations, allowing displacement combinations to be selected according to circuit count and flow demand. Aluminum-alloy housings and wear-resistant bushings are widely used, while axial-clearance compensation helps maintain operating efficiency.
The series features compact construction, low weight, broad applicability, and convenient maintenance. It can serve as a hydraulic power source for construction machinery, agricultural machinery, vehicles, and industrial hydraulic systems.
