The P.050 Ultra-Pure PTFE pump was engineered to take the cleanliness of diaphragm pumps to a new level. Machined Teflon® PTFE, plastic fasteners, integral piston diaphragm, and unique sealing techniques enable the P.050 to transfer corrosive liquids with low contamination and high purity. The Pro-Flo™  air distribution ,system is the driving force behind reliable 24 hour recirculation duty in semiconductor processing. The pump can be used on high temperature piranhan baths, etching solutions, photo-resist removers and recirculation duties.
