Internal Gear Pumps (common models include Sumitomo QT series, Hydac HG series) serve as one of the power components in hydraulic systems. Key information is as follows:

Core Features

Features an internal gear structure, offering compact size and low noise. Suitable for high-pressure (typically operating at 20-35MPa) hydraulic circuits with medium to low flow rates.

Typical Applications

Suitable for equipment like excavators, Loaders, and injection molding machines, primarily responsible for providing a stable hydraulic oil supply to the system and driving actuator movements.

Mainstream Brands

Includes Sumitomo, Rexroth, Sunny, etc. Different brand models correspond to varying flow rates and mounting interfaces.
