The Pentair WhisperFlo VST 2HP Variable Speed Pump (EC-011533) brings variable speed technology to the most trusted name in pool pumps. This powerhouse combines the proven reliability of the WhisperFlo line with cutting-edge energy efficiency, delivering more power than the SuperFlo VST while dramatically reducing your operating costs.
More Power, Less Energy
With a 2HP motor and impressive WEF 8.4 rating (THP 2.60), the WhisperFlo VST delivers superior performance while slashing energy consumption. Variable speed technology allows you to dial in the perfect speed for every task—low speeds for everyday circulation, higher speeds for cleaning and water features.
Seamless Drop-In Replacement
Upgrading from an existing Pentair WhisperFlo pump? This is your answer. The VST is engineered as a direct drop-in replacement, making installation straightforward with no expensive re-plumbing or modifications required. Get variable speed efficiency without the installation headaches.
Built for the Long Haul
Features a totally enclosed fan-cooled (TEFC) motor that shields critical components from debris, moisture, and the elements. This isn’t just durable—it’s engineered for years of reliable operation in the harshest outdoor environments.
Whisper-Quiet Operation
True to its name, the WhisperFlo VST operates remarkably quietly at lower speeds. Enjoy your backyard oasis without the constant hum of a traditional single-speed pump. Your neighbors will thank you.
Intuitive Programming
User-friendly controls make it easy to program multiple speed settings tailored to your pool’s specific needs. Set it once and let the pump optimize performance automatically, or adjust on the fly as conditions change.
Proven WhisperFlo Heritage
This isn’t a new, unproven design—it’s the evolution of the industry’s most trusted pump platform. You get decades of engineering refinement combined with state-of-the-art variable speed technology.
The WhisperFlo You Know, Smarter Than Ever
The WhisperFlo VST proves that you don’t have to choose between proven reliability and modern efficiency. It’s the best of both worlds in one exceptional pump.
