Centrifugal, or Variable Torque pumps, are used in a wide range of commercial, industrial and municipal applications. Throttling valves are a common flow control method. Compared to a throttling valve, the lower power requirements of the SMVector VFD provide a greater energy savings. Operating at 75% flow reduces power demand by over 50% with an SMVector Drive, while a throttling valve requires about 90%.

•Potable Water Pumps
Constant Torque pumps
Most Constant Torque pumps are also referred to as Positive Displacement (PD) Pumps. Using a VFD in these applications eliminates waste as the VFD tightly controls the volume pumped. While most VFDs are close to 100% starting torque, the SMVector Series offers 200% starting torque, allowing you to overcome the initial load. As a result, you can decrease the size of motor you are using, thus reducing the cost of the application.
