In hydronic heating and cooling systems, circulator pumps move water or refrigerant throughout a closed-loop system in order to transfer energy from the source to the point of need. While older ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Motors are rated by the output power they can produce over a given time period without overheating. These ratings are ...
