Tapflo PE and PTFE Series
PE & PTFE Series 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 solid laden. Polyethylene pumpsPolyethylene (PE HD) has a superior wear resistance which is 6-7 times better than 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 70C. PTFE pumpsPTFE (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 100C. ATEX approved -Pumps - PE & PTFETapflo ® pumps made from conductive (carbon filled) plastics PE or PTFE are made for use in explosion hazardous environments. They can be used in Equipment group IIG (gas), CAT 2 (zone 1). The conductive material ensures that no electrostatic loads will be accumulated in the pump. The conductive pigments in the material reduces the surface resistance to less than 105W. The pigments, causing the black colour, does not affect the chemical resistance of the thermoplastics. Transfer of alcohol and solvents are examples of applications for the Tapflo ® TX pumps. The TX pumps have diaphragms in PTFE (with conductive back) or EPDM (conductive). An earth connection is mounted on the pump, for earthing of electrostatic loads. All PE & PTFE series pumps are available as TX pumps.
