General Pump introduces a new electromagnetic mobile clutch assembly featuring a 9-3/4-inch, 2-groove pulley. The 2-groove pulley receives both “A (4L)” and “B (5L)” belts, and works for higher HP 59, 47 and 66 Series pumps. A one-piece solid, forged rotor means no chance of internal parts separation and offers torque maximization. When an electromagnetic clutch is used, pump life is extended. The new pulley is made of zinc-coated steel and is simple to install.
