Zodiac Polaris 7000/7240 Sport Impeller (R0766200)

The Zodiac Polaris 7000/7240 Sport Impeller (manufacturer part R0766200) is a purpose-selected replacement or equipment component for compatible pool, spa or aquatic installations. Its specific construction and application help technicians and owners maintain the intended equipment arrangement instead of making an uncertain substitution based only on appearance. When planning a repair, identifying the exact installed assembly is as important as identifying the replacement part itself.

The hydraulic role of the impeller

An impeller is the working hydraulic component that converts motor rotation into water movement inside a centrifugal pump. Its diameter, vane geometry, hub construction and relationship with the diffuser and volute affect flow and pressure. Even when two parts appear similar, an incorrect impeller can change the pump operating characteristics or physically interfere with surrounding components.

Installation, Compatibility & Care

When diagnosing low flow or unusual pump noise, inspect the strainer, suction path, diffuser, mechanical seal and motor before assuming the impeller itself has failed. Replacement should follow the pump’s service instructions; thread direction, retaining arrangements and required seals vary. Avoid running the pump dry or operating with a loose or misaligned impeller.

A correct replacement also protects the time invested in diagnosing and servicing the surrounding equipment. The best results come from comparing the old part with its service diagram, planning required accessories before disassembly, and checking the restored system under normal operating conditions. Where the equipment is part of a pressurized, submerged or electrically powered installation, follow the manufacturer’s shutdown, isolation and recommissioning procedures; a physically fitting component is not automatically approved for every application.

Practical Features & Service Considerations

• Hydraulic matching: use the pump’s exact wet-end and motor configuration to select the impeller.
• Mechanical clearance: confirm the replacement fits the diffuser and volute without binding.
• Inspection points: look for worn vanes, cracking, blockage or distortion during service.
• Related components: review the mechanical seal and diffuser when the wet end is disassembled.
• Assembly practice: follow the manufacturer’s retention and tightening instructions.
• Performance troubleshooting: confirm that suction restrictions or air leaks are not mistaken for impeller failure.

Before ordering: Compare the original equipment label and service diagram with R0766200. Verify any accessories or consumable hardware needed for the job; this product should not be mistaken for an entire system unless the listing expressly identifies a complete system.
