The Blackmer TXH3C is a 3-inch cast iron sliding vane pump designed for truck-mounted applications handling clean, non-abrasive, and non-corrosive fluids compatible with cast iron construction. This pump features horizontal parallel porting for easier piping connections and is designed for multiple mounting configurations. With flow rates ranging from 100 to 240 gpm and a maximum operating pressure of 125 psi, the TXH3C includes internal Blackmer mechanical seals, a double-ended drive shaft for clockwise or counter-clockwise rotation, and an adjustable relief valve for pressure protection. The sliding vane design provides self-priming capability with extended dry-run performance for tank trailer applications involving gasoline, diesel, jet fuel, biofuels, and petroleum products.
