Dosing, spraying, transferring, evacuating, and spreading a range of fluids are all possible using air-operated double diaphragm pumps. Perfect for typical applications requiring medium flow rates. Pump wetted parts are appropriate for use in corrosive situations and are compatible with even the most hostile fluids. Polypropylene is used to construct the air motor's directional air valve and air chamber covers. This particular model is an Ex II2 GD IIB/IIC 95 °C certified ATEX pump that is completely groundable. Strong acids (some above room temperature) and alkalis work well with this pump. For some potent alkalis or concentrated nitric acid, not advised.
