The Browning 3MVP50B64X Variable Pitch Pulley Sheave is used for varying the speed of different HVAC systems. This cast iron sheave has three V-grooves and comes with a 1-5/8” bore and an overall diameter of 6.68”. Variable pitch pulleys have the advantage of being able to change the speed of a system by changing the effective diameter of the pulley. This flexibility of speed control improves system effectiveness, optimizes the system, and decreases energy utilization in HVAC applications, including fans, blower, and pumps.
