Welcome to Flotronic Pumps - home of the "ONE-NUT" PUMP

A world leading manufacturer of air-operated Double Diaphragm Pumps, Flotronic (FPL) invented the revolutionary 'one nut' design - which is transforming the way in which Double Diaphragm Pumps are used in industry today.

This design allows in-line diaphragm replacement to be accomplished in less than 15 minutes, and a complete strip down and rebuild of the pump can be completed in less than 20 minutes. Using ONE - NUT pumps, engineers can significantly reduce process downtime and provide vast savings in maintenance costs without compromising on pump performance. Diaphragm lifetime is now so good that these pumps are often used instead of centrifugal or other process pumps.

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 'inside out' concept offers:

■ Longer Lasting Diaphragms
A significantly reduced stroke length allows use of thicker / stronger PTFE diaphragms as standard. Nitrile, Viton and EPDM 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 different series of pumps.
■ No Lubrication
A unique, patented air system incorporating a bolt on* spool valve, including manual override buttons, eliminates costly internal air mechanisms and mid position stall normally associated with Double Diaphragm Pumps.
■ Greater Inherent Safety
Plastic parts are kept within metal containment and potential leak paths are reduced to a minimum. Even under ATEX conditions pumps can be maintained in the zone up to Zone I using anti-static PTFE-faced diaphragms.

The 'one nut' Double Diaphragm Pump, unique to FPL, takes pump performance beyond the traditional-style, Double Diaphragm Pump. This fast maintenance concept literally turns the conventional Double Diaphragm Pump inside-out. Fluid passes between the diaphragms directly through the centre of the pump with air pressure operating on the outside. The pump is held together by one nut on the opposite side of the pump to the external air valve.
