BX series pumps are powered by a maximum air pressure of 8 bar. Performances refer to tests with cold, clean water with a density of 1000 kg/m3 (ISO9906) and to pumps with immersed suction and free delivery outlet.

STRENGTHS

VOLUMETRIC PUMPS

The BX AODD pump is a volumetric pump with pulsating flow rate. Two pairs of diaphragms inside them generate compression and depression: in this way the pump simultaneously creates vacuum (suction) and pressure (pumping).

THE ACCESSORIES

Three different delivery/suction positions. Possibility of split manifolds (two suctions and two deliveries). Optional features: automatic pulsation dampers, air adjustment kit, coupling flanges.

Air-driven double diaphragm pumps with no electrical components

DIAPHRAGMS AND BALLS

Pump materials: anti-acid plastic (PP, PVDF, ECTFE). Diaphragm materials: plastic (HYTREL, SANTOPRENE), rubber (NBR, EPDM), PTFE. Ball materials: PTFE, AISI 316, EPDM, NBR.

FDA, 3A, ATEX-COMPLIANT

Savino Barbera diaphragm pumps hold Atex Zone 2 certification (as standard). An Atex Zone 1 version is available by request. These AOOD pumps are also available in electro-polished (FDA certification) or mechanically polished (3A certification) AISI 316 for food, cosmetic and pharmaceutical use.

METAL FOR SPECIAL LIQUIDS

Metallic air-operated double diaphragm pumps for food processing, pharmaceutical and cosmetic industry

Our metal double diaphragm pumps are made of aluminium and stainless steel (AISI 316). In these two configurations, they can be used to pump difficult or hazardous liquids used in various industrial sectors such as: solvents, oils, fuels, high temperature liquids, etc… The BX membrane pumps are also available in electro-polished AISI 316 (FDA certified) or mechanically-polished AISI 316 (3A certified): these two special metallurgies are used for food, cosmetics or pharmaceutical applications.
