Flotronic Pumps

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.
