Application: Motor running a centrifugal pump. The pump ran full speed 24 hours a day with a bypass valve that was opened to maintain a constant 50 PSI of TMP water pressure on the line when valves downstream were throttling.

Application Specifications: 250 HP, 1800 RPM, 2300 volts, motor connected through an elastomeric coupling to a centrifugal pump. Horizontal application on skid.

Problem: The pump was running at full capacity during normal operations resulting in cavitation and excessive vibration. These factors created a high level of maintenance to the application. Energy was wasted when water was redirected through the bypass valve.

MagnaDrive Solution: Replace control valve operation with 18.5 MagnaDrive ASD. The motor was moved back on base and actuator was installed and connected to the process control system.

Customer Resolution: The MagnaDrive ASD eliminated the bypass valve with a potential energy savings of 633,333 kWh/year worth $19,000. The cavitation was eliminated and vibration was dramatically reduced, lowering long-term maintenance costs.

Customer Comments: The MagnaDrive ASD was chosen for this 2300 volt system because of the low equipment installation and infrastructure costs when compared to a Variable Frequency Drive. "We are excited about the potential for this equipment and have budgeted for future applications throughout the plant."
