Williams Comfort Products 5ES05H1GR Electric Solar Pump

Product Description

The WILLIAMS COMFORT PRODUCTS 5ES05H1GR is a 0.5 HP electric solar pump designed for solar thermal and hydronic circulation systems. Rated at 0.5 horsepower and wired for 4-wire, 3-phase operation, this pump moves fluid through solar collector loops, radiant heating circuits, or similar closed-loop systems. It ships as a single unit and is sized for installations requiring dependable, continuous-duty circulation in light commercial or residential solar thermal applications. A licensed plumber or HVAC technician is the typical installing trade for this class of equipment.

The 5ES05H1GR is suited for solar thermal systems, hydronic radiant heating loops, and similar fluid-transfer applications where a compact, 3-phase fractional-horsepower pump is specified. The 1-gallon displacement rating and 4-wire, 3-phase electrical configuration make it appropriate for installations served by 3-phase power, which is more common in light commercial settings or larger residential solar installations with 3-phase service. Install it per the system designer's piping diagram and applicable local mechanical codes.

Key Features

• 0.5 HP motor output for fractional-horsepower circulation duty
• 4-wire, 3-phase electrical configuration for compatible power supplies
• 1-gallon displacement rating suited to solar thermal and hydronic loops
• Single-unit packaging with a minimum order quantity of 1
• Designed for continuous-duty circulation in closed-loop fluid systems

Compatibility

Designed as an OEM-style replacement or new-installation pump for solar thermal and hydronic circulation systems requiring a 0.5 HP, 4-wire, 3-phase fractional pump configuration.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor familiar with solar thermal or hydronic systems and applicable local codes. Shut off all fluid supply and isolate the circuit before removing or installing the pump. Verify that the power supply matches the pump's 3-phase electrical requirements before energizing, and follow NEC guidelines for motor wiring and overcurrent protection. Do not run the pump dry, as cavitation or seal damage may result.
