The HYDSTAR® Hydraulic Gear Pump is a positive displacement pump that transfers and pressurizes hydraulic fluid through the rotation of two meshing gears. As the gears rotate, fluid is drawn into the pump inlet and carried around the outer circumference of the gears within the pump housing. The meshing gears then force the fluid toward the outlet, generating a consistent flow and hydraulic pressure. Designed with precision-machined gears and durable components, the pump provides reliable performance, smooth operation, and long service life in demanding hydraulic applications.

Attributes:

● Delivers consistent fluid flow and stable hydraulic performance
● Precision-machined gear profiles ensure accurate operation and reliable fluid displacement
● Durable construction provides excellent wear resistance and extended service life
● Suitable for a wide range of hydraulic applications and operating conditions

Applications:
The HYDSTAR® Hydraulic Gear Pump is widely used in hydraulic systems where reliable and consistent fluid flow is required. It provides efficient power transmission, stable hydraulic output, and dependable operation for construction machinery, agricultural equipment, industrial machinery, and other heavy-duty hydraulic applications. Depending on the pump design and configuration, it can handle a range of hydraulic fluids and operating conditions while maintaining consistent performance and efficiency.
