Membrane Pumps

Tapflo pumps made of polyethylene (PE) or PTFE can handle almost all types of liquids, including high-viscosity, chemically aggressive liquids, and those with solid particles.

Polyethylene (PE) Pumps

Polyethylene (PE HD) offers high abrasion resistance—6 to 7 times greater than polypropylene (PP). This makes these pumps ideal for transferring highly abrasive slurries. Polyethylene is resistant to most chemically aggressive fluids, including strong acids and alkalis. Maximum fluid temperature: +70°C.

PTFE Pumps

PTFE (pure polytetrafluoroethylene) is a thermoplastic polymer with exceptional chemical resistance. Pumps made from this material can handle even more aggressive substances than PE pumps, such as concentrated nitric acid. Maximum fluid temperature: up to +100°C.

The Tapflo hygienic pump series is specially designed for use in industries such as food, brewing, pharmaceutical, and cosmetics. An oil-free air distribution system, maintenance-free check valves, and full visual inspection of all wetted parts are the main advantages of this series.

Built to Stay Clean

The design allows full visual control of every component that comes into contact with the pumped liquid, eliminating hidden areas where bacteria can accumulate. To fully dismantle the wet end, simply release the quick-release clamp connections securing the inlet/outlet pipes and loosen the housing nuts. The pump can be cleaned and sterilized in place with piping (C.I.P and S.I.P cleaning). After cleaning, tilt it on its stand to drain any residual cleaning agents.

Explosion-Proof Version

All hygienic pumps can be manufactured to ATEX specifications and are available with a PTFE diaphragm (conductive backside) or an EPDM diaphragm (conductive).

Compactness, reliability, and simplicity are the hallmarks of this pump series. Materials: aluminum, gray cast iron, stainless steel, and PTFE-coated aluminum.

These pumps feature a simple, robust design and easy installation — we use about 70% fewer parts than competitors while maintaining strength and durability.

Aluminum & Cast Iron Pumps

Ideal for pumping neutral-pH fluids of any viscosity, including those with solids or abrasives. Commonly used in workshops, paint shops, and wastewater treatment plants.

AISI 316 Stainless Steel Pumps

Cast by lost-wax (investment) process for superior surface finish and dimensional accuracy. AISI 316 resists aggressive media such as nitric and hydrochloric acids. The non-wetted central block is made of corrosion-resistant polypropylene; other materials available on request.

Explosion-Proof Versions (ATEX)

All models can be manufactured to ATEX specification with a PTFE diaphragm (conductive backing) or EPDM diaphragm.

Tapflo powder pump can handle complex tasks in many industries and large production systems. Compact design also makes the pump mobile.

Reduced Contamination

Powder is transferred in a fully sealed pump system.

Cost-effective & Compact Solution

The Tapflo powder pump can perform the same tasks as many large-scale powder handling systems. Its compact design also makes the pump mobile.

What Types of Powders?

The powder pump can handle various process powders with bulk density from 80 to 720 kg/m³ of dry material. Generally, whenever the powder does not agglomerate when compressed by hand, a Tapflo powder pump is suitable. Examples include carbon black, resins, and silicones.

Performance

The performance of a single powder pump can vary significantly depending on powder consistency, density, and other factors.

High-density polyethylene (HDPE) offers superior physical and chemical properties compared to standard polypropylene (PP). It is several times more abrasion-resistant, making it ideal for abrasive and aggressive fluids. It can also withstand fluid temperatures up to 70°C.

PTFE Dampers

PTFE is well-suited for high-temperature applications. It can also be used with very aggressive liquids, such as chlorinated hydrocarbons and strong acids. Maximum fluid temperature – 100°C.

ATEX-Certified Dampers

Dampers are available in an explosion-proof version with ATEX certification. They feature grounding and conductive components: a conductive housing, PTFE diaphragm (conductive backing), or EPDM diaphragm (conductive).

Tapflo metal pulsation dampers for reducing vibration and pulsation in pipelines across various industries.

ALUMINUM DAMPERS

Aluminum dampers are ideal for use with pH-neutral fluids. They offer high resistance to corrosion and wear. You’ll find them in many industrial sectors—from workshops and paint shops to chemical plants.

AISI 316 STAINLESS STEEL DAMPERS

Stainless steel dampers combine high mechanical strength with excellent chemical resistance. AISI 316 withstands aggressive and abrasive fluids. The non-wetted dry section is typically constructed from corrosion-resistant polypropylene.

ATEX-CERTIFIED DAMPERS

Dampers are available in explosion-proof versions with ATEX certification. They include grounding and conductive components: a conductive housing, PTFE diaphragm (conductive backing), or EPDM diaphragm (conductive).
