Product Details
The Performance Pro WellSpring Submersible Pump with Flow Switch (WS-1/4-33-FS) is a premium, high quality water feature pump designed for simple, reliable installation directly inside your pond, skimmer box, or sump vault. This specialized version comes equipped with an integrated mechanical float switch that automatically handles start and stop operations, serving as an excellent safeguard for low water level conditions. Engineered with exceptional structural integrity for continuous duty operation, this 1/4 horsepower motor balances remarkable energy efficiency with heavy duty daily performance, making it the premier choice for professional installers and dedicated pond hobbyists looking to maintain steady, automated water movement.
Built to handle harsh underwater environments with minimal seasonal maintenance, the pump features a robust design combining high grade stainless steel and impact resistant plastic components to completely eliminate rust and corrosion concerns. The semi open impeller layout effectively minimizes clogging by allowing small debris to pass through smoothly, while a spring loaded mechanical seal meets strict API regulations with an impressive life expectancy of over 100,000 operational hours. For complete motor protection, waterproof cables and redundant seals safeguard the dry motor chamber, paired with an integrated thermal overload safeguard that automatically prevents terminal motor burnout during intense continuous operation. This unit also includes a convenient 2 inch barbed adapter fitting to streamline your plumbing installation.
