Diaphragm Pump TAPFLO PE – PTFE series made from polyethylene (PE) or PTFE are suitable for handling almost any kind of liquid whether it is viscous, chemically aggressive or with solids.
Polyethylene pumps (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.
| Industry | Example of applications |
|---|---|
| Chemistry | Acids, alkalis, alcohols, solvents, emulsions |
| Food | CIP liquids, flavours, pigments |
| Pulp & Paper | Glue, slurries, adhesives, dispersions, resins, sodium silicate, titanium oxide |
| Surface treatment | Acids, solvents, anodic sludge, varnish, enamels |
| Water treatment | Sludge handling, filter press applications, neutralization and flocculants |
| Electronics | Carrier fluids, ultra-pure liquids, electroplating solutions, mercury, solvents |
| Print & paint | Glue, additives, varnish, ink, paint, latex, acid, resins, pigments |
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 pumps 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.
Polyethylene Pump The hygienic model or PE Hygienic pump was developed to support work in the biotechnology industry. and pharmaceutical industry Can be used in many processes The pump is USP approved by the United States Pharmacopoeia.
Tapflo pumps made from conductive (carbon filled) thermoplastics PE or PTFE are made for use in explosion hazardous environments.
They can be used in Ex-zone 1. The conductive material ensures that no electrostatic loads will be accumulated on any pump surface.
The conductive additives in the material reduce the surface resistance. Transfer of alcohols or solvents are examples of applications for the Tapflo TX pumps. The ATEX directive 2014/34/EC (also known as ATEX 114) is applicable on products intended for use in potentially explosive atmospheres.
