Raypak 018232F Pump Diffuser & O-Ring Kit for RPVSP1If the pump is priming poorly, losing hydraulic efficiency, or leaking after wet-end service, the diffuser and sealing surfaces are worth checking closely. A damaged diffuser or flattened O-ring can reduce performance and create a wet-end leak that keeps coming back until the parts are replaced correctly.This pump diffuser and O-ring kit is used on the Raypak RPVSP1 pump assembly. The diffuser helps direct water flow through the impeller section, while the O-ring provides the seal needed at the mating surfaces. When the diffuser is cracked or the seal is worn, pump performance and sealing both suffer. Pump performance is weak because internal flow is not being directed correctly Wet-end leak develops after service or reassembly Diffuser is cracked, worn, or damaged during inspection O-ring is flattened, torn, or no longer sealing properly What this part does: It provides the diffuser and sealing O-ring used in the compatible RPVSP1 pump wet end.Compatibility: Designed for the Raypak RPVSP1.
