AIR OPERATED DOUBLE DIAPHRAGM PUMPS
BX SERIES: PLASTIC PUMPS
Double diaphragm pumps made of thermoplastic (PP, PVDF, ECTFE). Suitable for the movement of corrosive chemicals, viscous fluids and dense liquids. Maximum flow rate: 800 l/min. Maximum head: 8 bar.
BX SERIES: METAL PUMPS
Double diaphragm pumps made of metal (steel, aluminium). Compatible fluids: non-aggressive industrial liquids, flammable liquids, dense fluids and viscous products (oils). Maximum flow rate: 800 l/min. Maximum head: 8 bar.

INTERNAL DIAPHRAGMS
There are two pairs of diaphragms inside the BX pneumatic pumps and these are obviously the elements subject to the greatest stress during suction and pumping (both at chemical and mechanical level). The membranes are designed to redistribute the load, minimising the yielding of the material. The possible anti-acid and wear-resistant configurations are: plastic (Hytrel, Santoprene), rubber (NBR, EPDM) or PTFE.
THERMOPLASTIC MATERIALS

PP (POLYPROPYLENE)
The most widely used thermoplastic polymer for the construction of anti-acid centrifugal pumps. It offers good resistance to most acid and alkaline solutions and can be used, depending on the concentration of the aggressive liquids, at temperatures of up to 80°C.
