🔌 Pentair Sta-Rite HD 2.0 HP Three Phase Pool Pump
IE3 Premium Efficiency Commercial Powerhouse – Maximum Flow with Italian Engineering Excellence 🏅
📋 Product Overview
The Pentair Sta-Rite HD 2.0 HP Three Phase represents the flagship of the Sta-Rite HD range—combining maximum flow performance with IE3 premium efficiency and commercial-grade three-phase reliability. With an impressive 29 m³/hr flow rate at 8m head from a robust 1.5 kW motor, this pump delivers the serious circulation capacity that large commercial pools, leisure centres, and demanding installations require.
Manufactured 100% at Pentair’s state-of-the-art facility in Pisa, Italy, the three-phase 2.0 HP model meets stringent IE3 energy efficiency standards—the highest classification for motors of this power rating. This translates to 2–4% better efficiency than standard IE2 motors, delivering meaningful energy savings that compound over years of commercial operation.
Three-phase motor technology provides significant advantages over single-phase equivalents: balanced torque delivery, reduced vibration, lower heat generation, gentler starting currents, and substantially extended motor lifespan. For facilities running pumps 12+ hours daily, these benefits translate directly to lower maintenance costs and improved reliability.
The signature XL pre-filter basket handles the heavy debris loads typical of commercial facilities, whilst the PPO resin sleeved impeller delivers certified saltwater compatibility up to 0.40%. Backed by Pentair’s comprehensive 3-year warranty including bearings, the Sta-Rite HD 2.0 HP Three Phase is the definitive choice for commercial pool operators demanding maximum performance and minimum operating costs.
