Good To Know

Q: How can I tell the wear ring is worn? A: Excess clearance between the impeller and ring, cavitation on acceleration, or visible grooves and gouges on the ring surface all point to replacement. Measuring clearance confirms it.

Q: Is 155.5 mm the right size for my pump? A: This ring is listed at 155.5 mm ID for the Challenger SP 310 with the 1503 platform. Measure your existing ring and impeller before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
