High efficiency: QT internal gear pumps are the choice for servo systems and other hydraulic systems.
Structural Enhancements: Structural improvements further improve the QT Series, increasing its operating efficiency.
Noise reduction: The specially designed gear geometry of the Sumitomo QT gear pump significantly reduces noise levels, allowing for quiet operation even under high pressure and high speed rotation.
Comprehensive solutions: poocca hydraulics manufacturers offer complete pumps and accessories that can replace original Sumitomo products.
