CMA Vibratory Pump Brass Self-priming Valve

CMA Vibratory Pump Brass Self-Priming Check Valve

This brass self-priming valve is the check valve used inside Fluid-O-Tech vibratory pumps found in older CMA-built CK and CKE machines (circa 2004 and earlier). It keeps the pump primed by preventing water from draining back once the pump shuts off.

COMPATIBILITY

• Fits: CMA CK and CKE machines using Fluid-O-Tech vibratory pumps (ca. 2004 and earlier)
• Replaces: CMA vibratory pump self-priming valve (WY20366)

INSTALLATION

Requires removing the pump end cap to access the valve, straightforward with basic tools, though draining the water lines first is recommended.

PRO TIPS

• If your pump runs but won't build pressure or loses prime between shots, a worn self-priming valve is a common cause, check it before replacing the whole pump.
