Stainless Steel Slimline Pumps

Flotronic “One-Nut” ‘Slimline’ air operated double diaphragm pumps are particularly suitable for the hygienic and sanitary transfer of both low- and high viscous products in the food-, beverage-, cosmetic- and pharmaceutical industries. The pump material is conform FDA and  EU 1935/2004 and its addendum 10/2011. The PTFE material for diaphragms and seals comply to USP Class VI. These pumps can be supplied conform EU 2023/2006 Good Manufacturing Practises and are available with either 3A or EHEDG certification.

Flotronic’s ‘Slimline’ pumps are compact and the inside out design only has a minimum of product hold up, less waste of product and fast and easy cleaning. CIP is possible up to 6 bar and afterwards the pump drains without any further handling. The unique One-Nut design allows for pump maintenance in a matter of minutes.


Drum Unloading System

The Flotronic drum unloading system combines the unique ‘One Nut’ Slimline sanitary pump with a drum unloading skid. This pneumatical system enables you to pump all high viscous materials out of your drums in shortest time.

The pump suction side is connected to a followerplate that fits the inside of the drum. The follower plate has an inflatable seal that prevents against product spilling when the pump is emptying the drum. This way minimal wastage is achieved. The seal is deflated when the pump is pneumatically raised from the drum.


Minichem Pumps

A PTFE double diaphragm pump designed specifically for the safe transfer of aggressive chemicals and other hazardous liquids, at flow rates up to 100 litres/minute. The Minichem is machined from one solid block of PTFE; a unique patented concept based on Flotronic’s existing One Nut air operated double diaphragm design. A key benefit of the ‘One-Block’ design is that it avoids the need for separate manifolds. This means no manifold seals and therefore no potential leak paths.

Minichems pumps are available in both Virgin- and Anti-Static PTFE. Flotronic can supply ATEX certified Minchem pumps in Virgin PTFE material.

Chemflo PTFE Pump

Chemflo PTFE Pumps

The Chemflo range of PTFE air operated double diaphragm pumps have been specifically designed to handle your hazardous materials including aggressive chemicals. Crucial to the design is an outer Stainless Steel housing which supports and protects the main PTFE pump body which is machined from a solid block of PTFE / Teflon, through a range of pressure and temperature variations. This ensures a perfect seal is retained under all conditions.
