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.
Tapflo uses different grades of PE depending on the
part. For valve seats and ball stoppers, which are most
vulnerable to wear - UHMW PE1000 is used for best
mechanical strength and abrasion resistance.
PTFE (virgin polytetrafluorethylene) is a thermoplastic
polymer with superior chemical resistance. The PTFE
pump can handle even the most aggressive acids.
Maximum liquid temperature is 110°C
T400 and ATEX approved TX400 are our second largest pumps measuring 350 × 380 × 563 cm with a flow capacity of 570 liter/minute.
