Hayward HCP40753 HCP 4000 Series Pump 7.5HP 230/460V. Hayward Commercial self-priming pumps provide a technologically advanced alternative to traditional bronze or cast iron pumps. They have Thermoplastic, glass-reinforced hydraulic housings, so they're lighter weight for easier one-man installation. Impellers and flanges are made from glass-reinforced Noryl™. HCP pumps are quiet, efficient and designed to recirculate lightly
treated water in pools, spas and water features. They won’t rust in a chemically corrosive atmosphere. A clear lid allows visual inspection of the strainer basket, to see when it needs cleaning, and opens without tools. Four pumps in the Hayward Commercial Series allow right-sizing for most applications.
