E7 aluminum diaphragm pumps have a port size of 0.75 in. and feature a leakfree, bolted construction. Their shoe-valve design prevents blow-by when the pump is online but not in use. They employ the manufacturer’s Elima-Matic air-valve system, which ensures non-stalling, non-icing, lube-free operation. For use in lubrication, adhesive dispensing, OEM systems and many industrial applications, the E7 pumps are available with either metallic or non-metallic air sections.
