Pentair WhisperFlo 1.1 THP Single-Speed Pool Pump | EC-015583

Pentair WhisperFlo 1.1 THP Single-Speed Pool Pump | EC-015583

Pentair EC-015583 is the WhisperFlo single-speed pool pump. Choose this configuration by matching the pump’s electrical, plumbing and performance requirements to the installation.

What makes this configuration different

The 1.1 THP WhisperFlo uses a NEMA Premium efficient TEFC motor with 2-inch NPT suction and discharge ports. It provides a single-speed option for appropriately sized installations. Compare its performance curve against the actual circulation duty rather than treating the motor rating as a pool-size recommendation.

Size the pump for the complete system

Have your installer compare the manufacturer’s pump curve with your required flow and total dynamic head. Check the filter, heater, cleaner and sanitizer requirements as well as the suction plumbing. Neither horsepower nor a maximum flow figure alone establishes compatibility.

Installation and electrical planning

Verify the 115/208–230 VAC, 60 Hz supply requirements against the motor label and connection diagram. Provide the mounting, wiring, grounding, bonding and circuit protection required by the guide. Confirm applicable installation-location requirements before purchase.

Service and replacement planning

Keep the strainer and circulation path maintained where applicable, inspect for leaks, and follow the manual’s priming and shutdown procedures. Stop the equipment and relieve system pressure before opening pressurized components. Match replacement parts to the full model and production revision; visually similar pumps may use different drives, motors or hydraulic components.
