Main highlights- 【Powerful Performance】Delivering a robust 3.3 GPM flow rate and 50 PSI pressure, this pump effortlessly supports 3-4 water outlets simultaneously, perfect for showers, kitchens, and outdoor rinsing. With a 10FT self-priming capability and ultra-quiet operation (<55dB), it ensures reliable water flow while maintaining a peaceful environment.

- 【Energy-Efficient & Eco-Friendly Design】This pump consumes minimal power, making it ideal for RVs and solar setups. Its leak-proof design and double-density diaphragm structure prevent water waste, aligning with eco-conscious values and reducing environmental impact. The auto-shutoff feature stops the pump when water flow ceases, saving energy and extending its lifespan.
- 【Dry-Run Protection for Motor Safety】This pump features advanced dry-run protection, automatically shutting off when water is depleted or the system runs dry. By preventing dry running and motor burnout, it safeguards the motor, extends the pump’s lifespan, and ensures reliable operation in any condition.
- 【Advanced BLDC Brushless DC Motor】 This innovative brushless motor delivers higher energy efficiency, a longer lifespan, and robust protection against dust, water, and corrosion. It ensures precise, reliable operation while significantly reducing maintenance costs.
