The ECM Pump-Less-Volute is a new variable-speed version of the popular Gold Series Pump-Less-Volute. The ECM Pump-Less-Volute uses a permanent magnet motor that is up to 40% more efficient than a standard induction motor, the company says. Armstrong Pump-Less-Volute kits (PLV) are a complete repair solution for the Armstrong dry rotor S&H and 1050 & 1060 series. Armstrong standard and ECM PLVs also can be used to rebuild or upgrade select B&G or Taco circulator models. The ECM solution provides a very effective energy upgrade and is ideal for contractors who want to install a more energy-efficient pump without making changes to the pipe or the casing, Armstrong says.
