Blackmer (Grand Rapids, MI) has developed a 3-inch configuration for its piston air valves, to be used on its TX/TXD series of sliding vane pumps. In addition, the new 3-inch valve has now become the standard option for its TX/TXD pumps, replacing the diaphragm air valve. The new version incorporates the same features as the old 2.5-inch version, including a sliding piston; FKM elastomers that are UL-listed for compatibility with ethanol, biodiesel, and other biofuel blends; and quad-ring liquid seals. The TX/TXD series pumps are available in port sizes from 1.5 to 4 inches, flow rates from 10 to 500 gpm and relief valve pressures up to 125 psi.
