Permanent magnet pump

Armstrong introduces a medium range line of design envelope permanent magnet pumps engineered to deliver 20-per cent lower operating costs than variable speed pumps with standard induction motors. The pump motors range from 15 to 50 hp, and feature adjustable design points and setpoint based on onsite conditions, a quadratic pressure control curve, and a constant-flow function for maintaining a desired flow rate in recirculation applications.
