  • New: Flowserve Pleuger Permanent Magnet Motor Type PMM

        • Flowserve Pleuger Permanent Magnet Motor Type PMM

        • The Flowserve Pleuger PM motor has been developed for the highest possible energy efficiency.

          The permanent magnet technology guarantees approximately 10 percentage points better motor efficiency, resulting in a lower elevated temperature rise of the motor windings, increasing power output more than 100%.

          The PM motor construction is based on the reliable Pleuger three-phase AC submersible squirrel cage induction motor. Permanent magnet (PM) motors are rewindable, synchronous electric motors. Variable frequency drives (VFD’s) must be used to start PM motors and bring the motor up to synchronous speed.

          Submersible pumps equipped with a PM motor and a VFD are utilized to ensure the pump is operating at EP (Best Efficiency Point).

          The PMM8 motor technology has demonstrated over 93 percent efficiency, one of the most efficient eight-inch submersible motors on the market. Operated in conjunction with variable frequency drives, the PMM8 runs at synchronous speed with no rotor losses, which allows the pump to run at best efficiency point under variable flow conditions. Since the new PMM8 is available in the same diameter size as competitor units, customers will often be able to reduce their energy costs by upgrading to the Flowserve motor. Because of the high power output, in many cases the 8-inch PMM8 design can be substituted for conventional 10-inch asynchronous motors. Customers who have installed the PMM technology at their sites are very satisfied with the economic performance. Flowserve is one of the few companies which have both submersible pump and submersible motor competencies including permanent magnet technology.
