Swimming Pool Pump Motor Capacitor 50uF Compatible with Pentair Whisperflo, Superflo, Jandy Stealth, Hayward and Waterway Speed Pumps - 370V 50/60Hz (50uF ±5%, 2 Pack)

This motor run capacitor is designed to deliver consistent, reliable performance for swimming pool pump motors across major brands including Pentair, Hayward, Jandy, and Waterway. Engineered for continuous-duty operation, it provides a steady phase shift to help your motor run efficiently, reduce heat buildup, and extend service life. With a durable round aluminum housing and corrosion-resistant terminals, it’s built to withstand harsh outdoor environments, including high humidity and temperature fluctuations. Rated for thousands of hours of operation, this capacitor is ideal for both residential and commercial pool systems. Whether you're replacing a worn-out unit or performing preventive maintenance, this high-quality component ensures your pump operates at peak performance all season long.

• Specifically Designed for High Horsepower Pumps (1.5 – 3 HP): Built to handle powerful motors used in large pool systems such as the Pentair WhisperFlo WF-6, WF-28, WFE-6, WFE-28 (1.5 HP), WF-8, WF-30, WFE-8, WFE-30 (2.0 HP), WF-12 WFK12 (3.0 HP) Hayward TriStar 2.0 HP, and Jandy Stealth SHPF2.0. This 50µF capacitor is essential for high-load applications where startup torque and continuous power are critical.
• Delivers Stronger Torque and Better Motor Efficiency: Provides the ideal phase shift to keep high-wattage motors running at full strength. The improved torque profile minimizes motor strain, supports faster startup speeds, and reduces amperage draw, which can extend the lifespan of your motor windings and bearings.
• Built for Demanding Pool Environments: With a 370-volt rating, this capacitor is safe for use in pump systems that experience voltage fluctuations or thermal cycling. It is constructed to resist internal breakdown and swelling, even in outdoor enclosures exposed to full sun or splashback from pool equipment.
• Heavy-Duty Construction with Aluminum Canister Housing: The round, sealed aluminum shell provides excellent protection against rust, UV exposure, and water ingress. Terminal posts are clearly marked and built for a snug, secure fit, minimizing risk of arcing or shorts over long-term operation.
• Professional-Grade OEM Replacement: Commonly replaces part numbers such as 628318-307, 50/370R, and other 50µF run capacitors used in pool and spa systems. This model is not compatible with motors requiring 25µF or 30µF capacitors. Always verify exact uF and voltage on the existing motor label before replacement
