The hydraulically actuated diaphragm pumps provide leak-free metering of corrosive, flammable or hazardous liquids. They have removable check valves for inspection or cleaning without disconnecting piping. With capacities from 0.03 to 80 gal/hr simplex and 160 gal/hr duplex, the pumps handle pressures up to 3,000 psi. They can be adjusted while running by micrometer dial through 100 percent of their operating range.
