Linear-motor driven plunger pumps are most efficient at transforming mechanical energy to hydraulic work in low-producing and highly deviated wells. Linear-motor driven plunger pumps (LMDPP) are most ...

The three horsepower, printed circuit board stator, axial flux machine offers a sustainable solution for pump systems via greater power, efficiency, and durability in a smaller package. NEEDHAM, Mass.

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

High vibration is a common problem for motors installed on top of vertical pumps. Its source can stem from a mechanical issue with the pump, motor, or coupling — or even hydraulic forces from the pump ...

New water systems pump motors are designed for use as centrifugal pumps, jet pumps, and booster pumps. The capacitor start electrical designs offer superior starting torque at all times, states the ...

Everyone knows that airflow equals power, but what about fuel? All the air in the world won’t make one single horsepower if it isn’t mixed with the proper amount of fuel in the combustion chamber. To ...

Because peristaltic pumps can deliver a wide range of fluids, these pumps can be used in several industries. One example, according to Dave Beckstoffer, business development manager at Portescap, is ...

One of the principal NEC requirements for circuit protection is that you shut down the equipment rather than let supply conductors melt from overload. This can cause confusion, however, because Art.
