Restore the hydraulic assembly of a compatible Pentair commercial pool pump with this genuine C-Series 5 HP high head replacement impeller. When inspection confirms that a worn or damaged impeller is causing reduced pumping performance, replacing this component supports a focused repair.
It is specified for CH-50, CHK-50 and CHKL-50 high head pump models, including applicable single-phase and three-phase configurations. Match your complete pump model and existing impeller to the manufacturer’s parts diagram before ordering; a 5 HP rating alone does not confirm compatibility.
- Genuine Pentair part: An OEM replacement helps maintain the specified hydraulic configuration of compatible equipment.
- High head design: Choose the matching configuration for the listed C-Series high head models, not a medium head pump.
- Targeted repair: Replace the impeller while retaining other pump components that remain serviceable.
- Impeller only: The package includes one replacement impeller; identify any shaft seal, gaskets, washers or retaining hardware separately.
- Listed weight: 4.6 lb.
- Shipping dimensions: 5.5 × 5.5 × 3.12 inches.
Professional installation is recommended. Have a qualified pool equipment technician inspect the impeller, shaft seal, retaining components and surrounding assembly. Reduced circulation can also come from a clogged basket, dirty filter or suction restriction, so confirm the cause before replacing parts.
After installation, have the technician check for leaks and verify pump operation as part of routine commercial pool maintenance.
