Motors that drive pumps often consume significant amount of energy. In most cases the installation of a Variable Frequency Drive (VFD) is a great solution that translates into diminishing the cost associated with operating the motor, not only by saving money on electricity but also by decreasing the mechanical stress suffered by the system when starting always at full speed. Some advantages of installing a VFD are:

• System Ramps-Ups slowly: Avoid “water hammers” and excessive mechanical stress at starting.
• Saves Energy: Motor speed can be controlled depending on actual demand.
• Without a VFD it always run at full speed.
• Improved Control by Matching Speed to Changing Load Requirements.
• Lower Maintenance Costs: Lower speeds reduce wear and tear and provide longer live to bearings, seals, and couplers
