Monarch NSPHE-S150 Series Sprinkler Pump & Repair Parts
Monarch NSPHE-S150 Series Sprinkler Pump & Repair Parts
The Monarch NSPHE-S150 is a versatile mid-range sprinkler pump designed to provide the perfect balance of pressure and volume for residential irrigation systems. Powered by a durable 1.5 Horsepower (1½ HP) single-phase motor, this pump is engineered to draw water efficiently from lakes, ponds, or cisterns to keep lawns and turf green and healthy.
The NSPHE-S150 distinguishes itself with a heavy-duty cast gray iron casing and a precision-molded Noryl glass-filled impeller. This impeller design ensures a smooth surface for water flow, significantly increasing efficiency while resisting corrosion and abrasion. Unlike larger industrial models, the S150 features a square flange motor equipped with thermal overload protection, providing peace of mind against motor burnout during continuous operation.
Installation and maintenance are simplified with the NSPHE-S150. It features 1½” NPT suction and discharge ports and a built-in suction check valve that holds the prime, preventing backflow and eliminating the need for an external foot valve in many setups.
Key Features
- 1.5 HP Square Flange Motor: reliable single-phase motor (115/230 Volt) with a high service factor (1.47 SF).
- Thermal Overload Protection: Automatically shuts down the motor if internal temperatures rise too high, protecting your investment.
- Noryl Glass-Filled Impeller: Lightweight yet durable, offering high efficiency and resistance to rust and scale build-up.
- Self-Priming Capability: The large pump housing and integral check valve ensure fast priming and consistent performance.

Applications
- Residential Lawn Sprinkling: Ideal for medium-sized irrigation zones requiring up to 49 PSI.
- Garden Irrigation: Provides steady pressure for garden hoses and drip systems.
