Thermoplastic pumps
Tapflo pumps made from polyethylene (PE) or virgin PTFE are suitable for handling almost any kind of liquid whether it is viscous, chemically aggressive or with solids.
Polyethylene pumps
Polyethylene (PE HD) has a superior wear resistance which is 6 - 7 times better than for polypropylene (PP). This fact makes the pump suitable for handling abrasive slurries etc. PE is resistant to most kind of aggressive chemicals such as concentrated acids and alkalis. Maximum liquid temperature is 70°C.
PTFE pumps
PTFE (virgin polytetrafluorethylene) is a thermoplastic polymer with superior chemical resistance. The PTFE pump will handle even the most aggressive acids, for instance concentrated nitric acid. Maximum liquid temperature is up to 100°C.
Tapflo are now launching the first 
membrane pump in the company’s new aseptic series. The series will be available in three sizes for sterile applications in primarily the pharmaceuticals, bio-technology and foodstuffs industries. Owing to its special design this is the first Tapflo series to be approved according to EHEDG regulations.
