The SXC35/WTC50 Circmaster Kit is the most direct drop-in replacement on the market for the discontinued Aqua-Flo Circ-Master HP (CMHP / CMCP) spa circulation pump. The included split-union adapters let the SXC35 fit straight into the original Circmaster plumbing — usually with enough give in the existing pipework to screw on without any modification.

Before You Buy: Quick Fitment Checklist

• Orientation & space: Check whether your suction and discharge line up. The union adapters allow some rotation variance, but very rigid pipework may need a gentle tweak with a heat gun. Check pump dimensions in diagram to ensure this will fit in your spa.
• Remove any motor-mounting studs or blocks. As with any updated motor, these may need to be modified.
