Tapflo Design Features & Benefits

The Metal Air Operated Double Diaphragm Pumps have been innovatively designed with up to 70% fewer parts than other Air Operated Diaphragm Pumps on the market. Fewer components means a pump which is compact as well as easy & quick to maintain. The result is lower service costs and process downtime.

Design Features & Benefits Metal Series

Aluminium & Cast Iron Pumps

Metal Air Operated Double Diaphragm Pumps are ideally suited for the transfer of pH-neutral fluids, both thin, thick, solid laden or abrasive. The aluminum and cast iron pumps are found in most fields; workshop and paint industries, purifying plants etc., to mention only a few. They are also widely used for the transfer and batching of hydrocarbons such as diesel and varying oils such as lube oils, hydraulic oils & gear oils.

Stainless Steel AISI 316 Pumps

Cast via the “lost wax” method, ensuring greater accuracy and finish quality, the stainless steel pumps combine great mechanical strength with good chemical resistance. Stainless Steel AISI 316 is resistant to aggressive liquids like nitric acid and sodium hydroxide. The centre unit, which is not in contact with liquid, is made from corrosive resistant polypropylene (PP) as standard (other materials are available upon request such as carbon impregnated PP, Aluminium & Stainless Steel AISI 316).

Typical Applications

The Tapflo Air Operated Diaphragm Pumps are ideally suited to a plethora of applications in numerous industries, such as:



Workshops Oil, fat, solvents, water, cooling fluid, lubricants
Print & Paint Glue, additives, varnish, ink, paint, latex, acid, resins, pigments
