Chemical Processing


The Mega 255 is ideal for high flow chemical delivery applications. This pump features Trebor® non-centering magnetic shuttle that is proven to reliably operate under high pressure and closed discharge valve conditions. The fluid path is constructed entirely of PFA and PTFE to ensure high-purity pumping and chemical compatibility. 

The non-metallic air chamber components make this pump suitable for use in aggressive acid vapor environments.  The Mega 255 uses proven pump technology to consistently meet aggressive high flow fluid handling needs.
