The Monarch NSPHE-S150 Series Sprinkler Pump delivers exceptional high-pressure and high-capacity performance for residential and commercial irrigation or fire protection standby. Equipped with a built-in check valve (1⅓”, 2″, 2½” NPTF), it simplifies priming and prevents backflow, removing the need for a foot valve. Its Noryl glass-filled impeller ensures corrosion resistance, while 3 and 5 HP models use cast gray iron impellers for enhanced durability. The cast gray iron casing and diffuser optimize self-priming efficiency. The Monarch NSPHE-S150 Series Sprinkler Pump features CSA-approved motors (⅞ to 5 HP), with 1, 1½, and 2 HP single-phase motors including thermal overload protection and high NEMA service factors. The 3 and 5 HP JM frame motors provide robust power. With self-lubricating mechanical seals, the Monarch NSPHE-S150 Series Sprinkler Pump ensures low maintenance and reliable performance for all irrigation needs.
