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 pumps
Polyethylene (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 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.

Pumps - PE & PTFE

Tapflo 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.


  Special PE & PTFE Pumps

Drum Pumps - PE & PTFE

The Tapflo diaphragm drum pump has many advantages compared with conventional drum pumps. It is fitted with a drop tube in polypropylene (PP) or PTFE and a handle in stainless steel AISI 316L. The drum tube is delivered in any length up to 2m. Tapflo diaphragm drum pump has many advantages compared with conventional drum pumps.


Twin Inlet/Outlet Pumps - PE & PTFE

Tapflo PE & PTFE series pumps may be fitted with double in/outlet to achieve ”two pumps in one” for blending, mixing or re-circulation of liquids. The liquid in one pump chamber is separated from the other one.


Filter Press Pumps - PE & PTFE

The Tapflo pump station for filter-press feeding is a very compact unit that can be mounted directly to the filter-press. The design and function allows the user a straightforward pressing of slurries. Pressure regulator is already mounted to the unit. The pump stations are based on the standard Tapflo pumps from machined polyethylene (PE). An external pressure booster doubles the delivery pressure. For example, with available air pressure of 7 bar, the delivery pressure will be maximum 14 bar.
