The Blackmer TXV2.5B is a 2.5-inch sliding vane pump specifically engineered for high-temperature, high-volume transfer of thick, viscous fluids including asphalts, heavy oils, and industrial lubricants. This open-rotor design pump features bronze vanes and FKM elastomers for operation up to 375F with fluids up to 50,000 SSU viscosity. The double-ended shaft provides mounting flexibility with clockwise or counter-clockwise rotation capability, while external ball bearings ensure reliable operation in demanding applications.
