The PumpSaver® Model 234-P protects singlephase pumps from dry-well, dead-head, rapid-cycle, jammed-impeller, and over/undervoltage conditions. Typical applications include residential waterwells, commercial waterwells, irrigation wells, and golf course and other sprinkler systems. The PumpSaver® Model 234-P is designed to be mounted inside a Grundfos™ control box to protect 1/3–3hp, 2- or 3-wire, 230V pumps. An infrared LED communicates directly with a handheld diagnostic tool called the Informer (sold separately).
