I. QT Series Gear Pumps
1. Technical Features
• Low-Noise Design: Utilizes straight conjugate internal gear tooth profiles to eliminate trapped oil phenomena, significantly reducing noise and pressure pulsation. Even under elevated pressure or rotational speed, noise levels remain stable with high-quality sound, making operation nearly inaudible.
• Exceptional Wear Resistance: Straight conjugate gears, known as "non-wearing gears," are enhanced with specialized materials and processes to extend pump lifespan.
• High Efficiency: Improves efficiency through axial and radial pressurization, supporting pressures up to300 MPa. Features stable operation, minimal vibration, rapid response, precise actuation, accurate displacement, low power loss, and easy maintenance/operation.
• Versatile Applications: Ideal for high-speed applications, meeting diverse industrial demands.
2. Model Classifications
• Single Pumps:
Includes series such as QT22, QT23, QT31, QT32, QT33, QT41, QT42, QT43, QT51, QT52, QT53, QT61, QT62, and QT63, covering a wide range of flow rates and pressure requirements.
• Duplex Pumps:
Models like QT51-80-BP-Z and QT51-100-BP-Z are designed for scenarios demanding higher flow rates or pressures.
3. Application Fields
• Widely used in construction machinery, injection molding equipment, aerospace, agricultural machinery, and other sectors, providing reliable power for hydraulic systems.
