From the name of the inventor and PCM co-founder: René Moineau

PRINCIPLE OF MOINEAU™ TECHNOLOGY 

A Moineau™ pump consists of a helical rotor turning into a helical stator. When the rotor turns inside the stator, the honeycomb progresses spirally along the axis of the pump without changing either shape or volume. This action transfers the product from the pump suction to the pump discharge without degrading the product.

BENEFITS 

• Preserves the texture of fragile fluids (no shearing compared with lobe or ECP technologies)
• Handles fluids with solids
• High suction capability
• Self-priming
• Constant non-pulsating flow
• Reversible
