QT pumps feature internal gears that minimize operational noise level. The most outstanding characteristic is that because of their specially shaped tooth profile the noise level is almost constant even when the pressure becomes higer
Free from pressure ripples
QT pumps are almost free from pressure ripples, so they are ideal choice for systems which require accurate speed control such as machine tools.
In addition to their simple mechanism,the friction surfaces of all parts are forced-lubricated with high pressure hydraulic fluid which eliminates the direct contact between parts and minimizes abrasion of functional parts.The pumps can operate at a pressure as high as 320 kgf/cm2 even with inferrior lubrication fluids(water glycol,etc.) because of their extremely low abrasion.
With multi-stage construction, three pressure ratings, Low: 80kgf/cm2, Medium: 160kgf/cm2, High: 320kgf/cm2, and double pumps (combaination of single pumps) are available for wild applications. Plus newly developed “QT pump with motor” “standard power packs with QT pumps” are available.
