Tapflo Group, located in Sweden, is an independent family business. We specialize in manufacturing pneumatic diaphragm pumps, centrifugal pumps and other industrial equipment.
Tapflo is a leading pump manufacturer. We strive to provide high quality products of various specifications for industrial applications. Since 1970, Tapflo has been devoted to the treatment of industrial fluids and the design and manufacture of industrial pumps. We have a comprehensive and profound understanding of the needs of users in industrial pumps.
From the beginning of the production of the first pneumatic diaphragm pump, Tapflo has always adhered to the concept of simple structure, reliable performance, a small number of components, easy to maintain products. We are always sensitive to the needs of users and new industries. Therefore, we have been improving the details, materials and accessories of our products, so that our products are constantly improved and improved, more in line with the actual needs of users.
PE & PTFE Pneumatic Diaphragm Pump
PE & PTFE Series
Tapflo polyethylene (PE) or polytetrafluoroethylene (PTFE) pneumatic diaphragm pumps are suitable for almost all types of media, whether viscous, chemically aggressive or containing solid particles.
All Tapflo pneumatic diaphragm pumps have features common to very few components and compact designers. The pump with simple structure can be maintained conveniently and quickly. It can effectively save the maintenance cost of users and shorten the downtime.
Polyethylene Pump (PE)
The wear resistance of high density polyethylene (PE HD) is 6-7 times stronger than that of polypropylene (PP). Therefore, our PE pump can be used to transport abrasive media such as mortar. PE material can withstand most kinds of high concentration acid and alkali liquor. The maximum temperature of withstandable medium is 70 degree C.
PTFE pump
PTFE (pure polytetrafluoroethylene) is an advanced chemical-resistant thermoplastic polymer, which can resist strong corrosive acids, such as concentrated nitric acid and aqua regia. The maximum temperature of withstandable medium is 100 degree C.

1. Flexible installation
The inlet/outlet tee can rotate 180 degrees. After simply rotating and adjusting the angle, it can be easily connected to the pipeline. Plastic series standard BSP or NPT internal threads, also can choose AISI 316 or other connection.
2. Solid pump body
The pump body is made of rugged PE or PTFE and can withstand high mechanical strength and corrosive chemicals.
3. Design for Chemical Medium
Composite diaphragm with smooth and complete surface ensures that there are no metal parts on the contact surface. It is an ideal choice for transporting chemical liquid.
4. Less gas consumption
The valve design with short air path and no "dead angle" reduces gas consumption and greatly improves work efficiency.
