Hayward SP1580/SP3000 Wear Ring Lower HP (SPX3005R) couplings The Waterway 640-2001 spa drain/fillThe wear ring helps manage the clearance between the impeller and pump housing so water can move efficiently through the pump. This lower horsepower replacement wear ring is designed for compatible Hayward SP1580 and SP3000 pump models. When a wear ring becomes worn or distorted, pump efficiency can drop and internal noise may increase. Replacing it during seal, impeller, or housing service can help restore better hydraulic performance.
