Description
The Danfoss Group 1 aluminium motor offers high efficiency and excellent starting torque thanks to its lightweight construction.
Its pressure-balanced bearing blocks enable maximum performance across its operating range. While Teflon®-coated bushings extend life under extreme temperature, pressure and speed conditions. One-piece gears minimise deflection under pressure.
