Yilmaz Reduktor KR and DR-Series gearboxes are designed with a drywell feature to prevent oil leakage. Oil leakage can also be detected using an optional oil sensor on the gearbox. Fitted with spherical roller bearings, special seals and an oil leakage pool, the KR and DR series range is a perfect solution for wastewater treatment plants where slow speed and high output torque is required from the geared motor. Rotating bridge scrappers, fixed bridge scrappers and sludge thickeners are typical applications.
