Hayward Matrix SP1591 SP1592 SP1593 Volute (SPX5500A) topsideoverlays and plumbing layout before installationThe Hayward volute is designed for compatible Matrix SP1591, SP1592, and SP1593 pump applications where the main wet end housing needs replacement. A volute like this is useful because it forms the chamber around the impeller and helps direct water through the pump, making it essential to hydraulic performance and structural integrity. This replacement is especially useful when the original volute is cracked, warped, leaking, or otherwise too damaged
