    COSMOSTAR Diaphragm Pumps

    COSMOSTAR Air-Operated Double Diaphragm Pumps series are ideal for bulk transfer of your solvent or water-based, low to medium viscosity inks and ingredients. They offer easy maintenance with an extremely reliable patented air valve for true non-sticking operations. Air-operated double diaphragm pumps are a very efficient type of transfer pump. These pumps can handle liquids with high, medium or low viscosities. They are also designed to pump liquids that feature a considerable amount of solids. This type of pump can be constructed out of materials that can handle pumping even the most acidic chemicals. Our double diaphragm pumps are designed to operate at low air pressure while delivering a smooth, reliable flow. This is ideal for transferring a wide variety of fluid. Installed with Teflon plate at each of the diaphragm compartments, double diaphragm pump guarantees high endurance and durability.
