Hayward TriStar® Full Rate Single Speed Energy Efficient Pump 1HP 115/230V. The TriStar pump’s advanced hydraulic design optimizes the three essential pump elements to deliver superior flow, impressive energy efficiency and value. The heavy-duty pump and motor run cooler for years of dependability. Featuring a tri-lock cam and ramp strainer cover that closes with less than a quarter turn, TriStar also sports a super-sized, smooth, no-rib basket with extra leaf-holding capacity that’s a snap to clean. With a variety of bases available, TriStar seamlessly retrofits to existing filtration systems.
