E-CTFE Halar® Nesk pump

Main pumped products


One of the best techno-polymers known for its chemical and mechanical resistance. Pumps made of E-CTFE can pump any kind of liquid: highly corrosive, abrasive, hard liquids and even with high temperature. Thanks to its structure, E-CTFE offer a superior robustness to pumps and therefore improves reliability and durability.
