Products > Air Operated Double Diaphragm Pump > PE & PTFE Series

  • Compact and robust design from machined PE or PTFE.
  • The PE has a wear resistance 6-7 time higher than PP and 1.5 times higher than steel, which makes the PE pump ideal for abrasive slurries.
  • The PTFE pump even resists the most aggressive liquids such as concentrated Nitric Acid.

Drum Pumps TD

The Tapflo drum pump is ideal for mobile use. It is fitted with a drum tube in PE or PTFE and a handle in stainless steel AISI 316L.

Twin Pump TT

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

TF filterpress Pump Stations

The Tapflo pump station for filterpress feeding is a very compact unit that can be mounted directly to the filterpress. The design and function allows the user a straightforward pressing of slurries. Pressure regulator is already mounted to the unit.
