The Conical Spring Mechanical Seal is a compact, single-coil pusher seal engineered for single-direction rotating shafts. It features a tapered, heavy-duty spring that grips the shaft directly to transmit torque, eliminating the need for drive pins or set screws. Its open, single-coil profile prevents clogging, making it highly reliable for handling clean, viscous, or lightly contaminated fluids.
