Monarch NSPHE-S100 Series Sprinkler Pump & Repair Parts
Monarch NSPHE-S100 Series Sprinkler Pump & Repair Parts
The Monarch NSPHE-S100 is the foundational model of the NSPHE series, offering reliable performance for homeowners needing a dependable 1 Horsepower (1 HP) solution for lawn and garden irrigation. Designed for efficiency and longevity, this self-priming pump is capable of delivering high capacities required for residential turf sprinkling while remaining energy efficient.
Encased in a rugged blue cast gray iron housing, the NSPHE-S100 is built to resist environmental wear. Inside, it features a precision-engineered Noryl glass-filled impeller. This lightweight, smooth-surface impeller ensures maximum water flow efficiency and is highly resistant to corrosion and scale buildup, a common issue in metal impellers.
The unit is powered by a high-service factor (1.65 SF) square flange motor equipped with thermal overload protection. This safety feature automatically shuts the pump down to prevent burnout if it overheats, ensuring years of trouble-free service. With a built-in check valve to hold prime, the NSPHE-S100 is the “set it and forget it” solution for your irrigation needs.
