The 'no-hole' diaphragm pump design incorporates a smooth-surface, compound diaphragm that has a perfectly clean face with no fixing bolt with no dead space.
The diaphragm's smooth liquid-side surface ensures that no metal is in contact with the liquid being pumped.
Mick Barnes, managing director of Tapflo commented: "The Tapflo design is unlike many competitive systems that have a metal shaft protruding into the liquid.

Our customers are of the opinion that there is no point in buying a diaphragm with a hole already in it".
This design has enabled Tapflo to secure many large orders from leading blue chip companies looking for guaranteed 'no leak path' pumps.
Using its PBS2 barrier systems for leak detection and pump control, the Tapflo design minimises leakage and contamination and diaphragms are available in PTFE, EPDM, NBR, food grade EPDM and PTFE to suit all types of materials.
No lubrication is required producing a pollution free system and, in addition, because Tapflo pumps do not require an electrical supply, they are ideal for applications in ATEX areas.
Another important feature is the air distribution system within Tapflo pumps that is designed to eliminate 'dead spaces' resulting in higher efficiency and lower air consumption.
To provide maximum strength, both the HDPE and PTFE and Hygienic HDPE series are machined from solid blocks and the system is highly flexible because the design is such that connections can be rotated 180 degrees to suit the piping configuration.
Tapflo pumps are compatible with a very wide range of chemicals, are FDA approved and Tapflo has achieved ATEX certification Group2 Category2.
The product range includes pumps made from aluminium (both standard and PTFE coated for paints and ink), stainless steel, many kinds of plastic and cast iron for use in mines.
Systems include drum and barrier pumps, pulsation dampeners, filterpress pumps and hygienic and pharmaceutical pumps and are suitable for all pneumatic systems and controls including level, batching and barrier life counters and similar applications.
