The White Knight AP EXT Series pumps are constructed from 100% PTFE and PFA in the liquid path. The air side does contain a ceramic sleeve and spool and some polypropylene. AP EXT Series pumps are capable of pumping liquids at a constant or thermal cycling 100º Celsius. The AP EXT Series pumps are simply AP Series pumps which have reduced liquid orifice for the purpose of reducing the speed of the pump thereby lengthening time between re-builds.
