Stop wasting electricity

Losing 61% of the electricity you buy is unacceptable. Novomet attacked the two biggest energy wasting components in an ESP—the pump and the motor—to develop the PowerSave system.

We started by designing an energy-efficient, high-speed pump that would operate at higher RPMs. Using powder metallurgy, we manufacture parts with a level of precision that is not possible using industry-standard sand-cast manufacturing. This enabled us to redesign the pump using new geometries, and to reduce the overall pump length to one-third its previous size—while maintaining pump capacity. Advanced pump stage geometries and an upgrade in materials combined with the shorter pump length to dramatically reduce heat and wasted electricity.

The next step was the motor. Typical induction motors use motor windings to create magnetic induction. Having to create this induction causes heat, wasting electromagnetic energy. So we designed and developed a permanent magnet motor that eliminates the need for an induction rotor. The PMM rotor uses rare-earth alloy magnets with two ports where north and south poles interlace to reduce the power needed to turn the rotor. Stator laminations are made from proprietary Novomet material, further improving the magnetic field. As with the pump, PowerSave permanent magnet motors are shorter and lighter than induction motors. The result is a light-weight, powerful motor that runs cooler and uses less electricity.

The most efficient electricity is the electricity you never use

The high-speed pump and permanent magnet motor combine to reduce ESP power consumption by 25–30% and reduce overall system length by 60%. Put another way, the PowerSave system can reduce your carbon emissions related to running ESPs by 30%.
