Do you want to save money and energy on your next portable pump system? 

Instead of using traditional motor starters, use a variable frequency drive to power and control your portable pump cart.  Not only do these types of drive excel at controlling industrial electric three phase motors on pumps, they are also like mini energy management solutions. 

The sensorless vector style drives are used for constant torque and are great for positive displacement type pumps (gear pumps), as well as centrifugal pumps. Many variable frequency drive models are multi-type, meaning both vector type and volts to hertz type. 

High performance AC drives are also ideally used for both indoor and outdoor applications and can be supplied with the proper enclosure for either environmental condition. 

The variable frequency drives,  like AC Tech Drives, Lenze and the other brands that Marshall Wolf Automation distribute, are available with 120/1/60hz input or 230/1/60 HZ power, making them ideal for small horsepower pumps used in outdoor applications where power choice would be limited. 

In regards to larger horsepower, typically greater than 3 HP pumps, other models of 3 phase drives can be wired up for single phase when properly derated, ensuring that these components are rated for the higher current that will flow from the single phase input instead of the three phase input. 

Simply put the basic formula is: (VFD current > Motor current rating (FLA)* 1.73). Please contact us at 800-325-9653 or visit www.wolfautomation.com  for your unique application and we will help you choose the best variable frequency drive for your portable pump needs.
