Mazzei ® Venturi Injectors

Mazzei Venturi Injectors

We import and supply Mazzei Venturi Injectors, which are precisely engineered and cannot be duplicated. Imitations and look-alike products simply do not perform like a Mazzei. The U.S. Patent and Trademark Office awarded Mazzei a trademark registration for its unique look and shape.

The internal vanes deliver superior suction capacity at low differential pressure. The injector’s trademark look represents Mazzei’s acquired reputation among consumers for years of quality and performance. The Mazzei look is recognized internationally, so it is important to make sure the injector is a Mazzei. To confirm that an injector is a Mazzei, a customer should check for the Mazzei name on the injector, then buyers can be assured that they are getting the best and most effective mixing and contacting available.
