KTR Hydraulics
Hydraulics
KTR hydraulic components are engineered for high-pressure power transmission environments, combining precision-machined pump carriers, thermally optimised oil coolers, and vibration-absorbing damping elements into a cohesive system portfolio. Oil/water coolers handle heat exchange duties across flow rates from ca. 20 to 400 l/min, while KTR damping rings reduce torsional vibration peaks by up to 50% - meeting ISO 4413 hydraulic system safety requirements. Flanges and pump carriers conform to SAE J744 and DIN 24340 mounting standards, ensuring drop-in compatibility with leading gear and vane pump series.
As an authorised KTR distributor, fluidics-equipment.com stocks over 11,352 KTR hydraulic articles - spanning drive technology, thermal management, oil tanks, temperature sensors, and tank heaters - all compliant with ISO 4413, DIN EN 14359, and DIN 24340 for industrial hydraulic power units.
