PE & PTFE series pumps
Tapflo pumps made from polyethylene (PE) or virgin PTFE plastics are suitable for handling almost any kind of liquid whether it is viscous, chemically aggressive or with solids.
Few components and a simple but ingenious design is peculiar for all Tapflo pumps. It is a compact pump, easy and quick to maintain, keeping your service costs and process down time to a minimum.
Polyethylene (PE) 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 (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.

1. Flexible installations
The connections may be rotated 180°. Simply turn the connections to fit your piping system. Threaded BSP orNPT plastic connections is standard, AISI 316 or other connections types are also available.
2. Solid and strong
The pump body is machined from solid PE or PTFE. The solid design will stand against mechanical forces as well as aggressive chemicals.
3. Chemical design
The compound diaphragm has a completely smooth liquid side surface and with no metal in contact with the liquid. Ideal for a safe chemical handling.
4. Low air consumption
The air distribution system is designed with shortest possible air distribution ways. This eliminates "dead spaces", resulting in high effiencey and low air consumption.
