Samoa Industrial Double Diaphragm Pump DF50 1/2" Acetal/PTFE DF50PDSTTBAS
|
Air-operated double diaphragm pumps for dosing, spraying, transferring and distributing a variety of liquids with low to medium flow rates. The pump's wetted parts are suitable for even the most aggressive liquids and use in corrosive environments. The air motor (pneumatic directional control valve and air chamber covers) is made of polypropylene. DF50T are double inlet pumps for mixing liquids of comparable viscosity in a 1:1 ratio. Both the initial liquids and the resulting mixture must be compatible with the pump's wetted materials. For use in potentially explosive atmospheres, fully groundable pumps with ATEX certification are available (Ex II2 GD IIB/IIC 95 ˚C).
Application
ATEX pump. Solvents (ketones, acetates, aldehydes, aromatic
and chlorinated hydrocarbons) and solvent-based paints and varnishes.
