Medium Permanent Magnet Pumps
Armstrong Fluid Technology introduces a new size range of Design Envelope permanent magnet pumps engineered to deliver 20% lower operating costs than variable-speed pumps with standard induction motors. They are available with motors ranging from 15 hp to 50 hp, and operate at NEMA Ultra-Premium Efficiency levels. The patented Parallel Sensorless Control stages multiple pumps and regulates output for best efficiency across the entire pump array. Adjustable design points and setpoint are based on actual on-site conditions. A quadratic pressure control curve provides more efficiency than a linear pressure control curve. A constant-flow function maintains a desired flow rate in recirculation applications.
