Couldn't load pickup availability
Brand / System Insights: Pentair’s C-Series bronze pumps are designed for commercial duty, using heavy construction and OEM components. Medium-head impellers are formulated to offer sufficient lift for filters and plumbing without pushing motor into inefficient operating points.
Warranty Info: OEM Pentair parts are covered under Pentair’s parts warranty when installed correctly and using genuine Pentair components. Warranty may require proof of proper maintenance.
Q: Is this impeller compatible with both single-phase and three-phase motors?
A: Yes. SKU 070227 is used in both 1-phase (CM-75) and 3-phase (CMK-75 / CMKL-75) C-Series pump models. Q: How do I know if I need medium head vs high head impeller?
A: Check your system’s plumbing, filter resistance, and desired flow. Medium head offers more flow with lower head, which is suitable when plumbing losses are moderate. High head versions are used when plumbing or filter back-pressure is large.

Description
The Pentair Medium-Head Impeller (SKU 070227) is intended for replacing deteriorated impellers in Pentair’s commercial bronze C-Series pumps, particularly the 7.5 HP units. Employing a medium head profile, it maintains a balanced hydraulic curve that delivers sufficient lift without placing undue strain on motor or plumbing. Installation is straightforward for anyone familiar with pump disassembly, and because it’s an OEM Pentair component, fit and sealing are reliable.
Pro Tip
Before assembly, inspect the volute for pitting or wear and the impeller shaft for straightness. Always use a new gasket and apply proper torque to fasteners. If you notice reduced performance post-replace, check pump housing and piping for restrictions that may mimic impeller failure.

Installation Tips
Power must be turned off and locked out before servicing. Confirm the impeller matches the pump’s horsepower and phase. Ensure shaft key is in place and not worn. Use correct gasket sealing and check that volute and impeller alignment are correct to avoid vibration and leakage.
