Aluminium pump include all wetted parts coated with non stick PTFE, is equipped with stainless steel in/outlet ports.
The model was developed for the printing industry where a low price alternative of the PE/PTFE pumps was required but aluminium not chemically resistant. It can be used for all sorts of applications where slightly acidous or alkaline liquids need to be transferred.
However, in applications with highly aggressive chemicals, we still recommend our full plastic PE & PTFE series pumps.
