V Pulley
Adjust your machinery to the strictest of standards with adjustable speed v belt pulleys from HZPT. Our adjustable speed v belt pulleys support applications with drive-speed refinements, including pumps, fans, blowers, and more. Stop worrying about adjustment frustrations because an adjustable speed v belt pulley from our stock is easy to work with in any application. Slip the variable drive pulley onto your machine, and adjust it from that point forward. Speed adjustments are part of the pulley's design benefits. The secret is within the threaded, angular-faced discs that are the core of the V-shaped groove on each pulley. If you need more speed, move the discs toward each other. This alignment produces a belt that simply rides higher in the groove. Achieve a larger pitch diameter than before with this adjustment. Meet every requirement in your industry by slowing the machinery down to a specific rate. Simply increase the space between the two discs, which slows down the belt's motion. At HZPT, our adjustable speed v belt pulleys give you the necessary versatility to refine your machinery and move forward with a productive day.

Adjustable Speed V Belt Pulley Application
The most common reason is for mechanical drive speed variation. A great deal of drive speed refinement is possible with the use of adjustable speed v belt pulleys and they are used on fans and blowers and industrial water and trash pump applications. Adjustable speed v belt pulleys allow for mechanical drive speed variation that is economical, easy to install, and easy to adjust. In just seconds a technician can increase or decrease drive speed.
The principle of a adjustable speed v belt pulley is that the threaded angular faced discs forming the V-shaped groove, in which the belt rides, are movable. When the discs are moved toward each other, the belt rides higher in the groove and the pitch diameter of the sheave is larger, which increases the driven speed. When the discs are moved away from each other, the belt rides lower and the pitch diameter is smaller decreasing the driven speed. In contrast, with a “fixed pitch” drive design you are limited to a specific drive speed, which is a direct result of the “fixed diameter” of the sheaves.
Drive speed variation can be extremely valuable as a system is commissioned. Adjustable speed v belt pulleys are a simple method to vary fan speed to meet the required air flow specifications, allowing the system to be compliant with all engineering and regulatory requirements. Using a “fixed pitch” design would require a sheave combination change out to alter the driven fan speed, which is both time consuming and more costly. Using a variable pitch drive design can also help reduce zone air flow without relying on inefficient dampers, which restrict the air flow. Using adjustable speed v belt pulleys allow the motor and fan to operate at optimum speed characteristics.
