Frequently Asked Questions

Is the Monarch SPHE pump suitable for continuous use?

Yes, the SPHE series is designed for heavy-duty applications. However, like most sprinkler pumps, it is designed for intermittent cycles typical of irrigation systems rather than 24/7 industrial continuous duty.

What voltage does the Monarch SPHE pump require?

The SPHE pumps utilize a dual-voltage motor that can run on either 115V or 230V (Single Phase, Capacitor Start). Check your specific model’s wiring diagram for configuration.

What are the suction and discharge sizes?

All models in the SPHE series feature a 2-inch NPT suction port and a 1-1/2-inch NPT discharge port.

Does this pump come with a warranty?

Warranty terms can vary by distributor, but Monarch pumps generally carry a manufacturer’s warranty against defects in materials and workmanship. Please check with your retailer for specific coverage details.
