Flotronic is a world leading manufacturer of air-operated Double Diaphragm Pumps and inventor of the revolutionary ‘one-nut’ design – a concept which has transformed the way they are being used throughout the industry.

The ‘One-nut’ Concept

The ‘inside out’ concept allows fluid to pass ‘between the diaphragms’, directly through the centre of the pump. Air pressure operates ‘on the outside’. The benefits are:

Longer lasting diaphragms

An optimised stroke length allows use of thicker / stronger PTFE faced diaphragms as standard. One-Piece Nitrile and EPDM diaphragms are also available.

Faster Maintenance 

Fifteen minutes to change diaphragms by the removal of just one nut and without disconnecting the pump from the pipework.

Lower cost spares

Less than half the quantity of spare parts than any equivalent pump and interchangeability of most air system parts between the different pump styles in our range.
