Diaphragm Pumps Ltd

Flotronic Air Operated Double Diaphragm (AODD) Pumps are becoming the most common pumps for use when Only Air is available or when pumping solid laden liquids or slurries. Flotronic Diaphragm Pumps have no seals as the diaphragm acts as the barrier between the Liquid side and the drive side of the pump. When the liquid pressure reaches the air pressure, the Flotronic pump reaches a point of balance and stalls without the need for bypasses or overload protection.Flotronic Diaphragm Pumps pump can run dry indefinately and have the ability to self prime to 7 metres or more in some cases. They can handle viscosities up to 20000 Centipoise as standard and some Flotronic models can handle cPs into the 100's of 1000's. Flotronic Pumps are some of the most reliable AOD's in the marketplace, Self Priming, Dry running, Intrinsically safe, these are just a few of the features of Flotronic Diaphragm Pumps. Models include pumps for pumping hygienic products, aggressive chemicals aswell as standard industrial duties. High pressure models are also available for filter press applications or for pumping into closed systems. ATEX regulated Flotronic pumps are offered for Zone 1 environments. Flotronic Pumps and spares are available from Diaphragm Pumps Ltd, Stoke On Trent, England. As one of the largest stockists of pumps and spares in Europe, we hope we can supply all your Flotronic Pump needs.

Diaphragm Pumps Ltd. Is an official re-seller of Pumps and Spares for Flotronic Pumps
Flotronic is a world leading manufacturer of air-operated Double Diaphragm Pumps and inventor of the revolutionary ONE-NUTTM design - a concept which is transforming the way pumps are being used throughout industry today.

The One-Nut Double Diaphragm Pump, unique to Flotronic, takes pump performance far beyond traditional style Double Diaphragm pumps. This fast maintenance concept literally turns the conventional 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.

This design allows in-line diaphragm replacement to be accomplished in less than 15 minutes, with a complete stripdown and rebuild possible 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, these pumps are often used instead of centrifugal or other process pumps.
