Browning 1VP62X7/8 Variable Pitch Motor Pulley 7/8" Bore

The Browning 1VP62X7/8 Variable pitch motor pulley with a 7/8” bore diameter. It is intended to control the frequency of motors in HVAC systems to control the flow rate and temperature. Variable pitch pulleys have two sets of grooves, one having the fixed pitch and the other one having the variable pitch. In this case, the pitch diameter of the pulley can be changed by shifting a movable sheave. This changes the rate of the motor and therefore changes the rate of the fan or blower that is used.
