Air operated double diaphragm pumps for dosing, spraying, transferring,
evacuating and distributing a wide variety of fluids. Ideal for standard
applications with medium flow rates. Very robust metal pumps designed
for the toughest applications. This model is a fully groundable ATEX
certified pump, for use in potentially explosive atmospheres (Ex II2 GD
IIB/IIC 95 ˚C). This pump is good for chemicals compatible with
stainless steel and aluminium. Solvent (ketones, acetates and aldehydes,
aliphatic and aromatic hydrocarbons) and solvent based Paint, inks and
varnishes. Stainless steel balls allow its use with higher viscosity
fluids. NOT FOR CHLORINATED HYDROCARBON Solvent. VIDEO Youtube:
