Blackmer has designed its TXV pumps to provide high-volume, low-speed transfer of asphalt. The key to the TXV’s performance in these applications is the pump’s unique sliding vane rotor design that provides sustained, high-level performance over a wide viscosity range. In addition, the pump’s ability to offer slow operating speeds and non-pulsating flow minimizes shear and product agitation. The pumps are also self-priming and can run dry for short periods of time for priming purposes.

TXV pumps are available in 2.5- and 3-inch port sizes. The standard cast-iron construction includes a special open-rotor design that offers easy flushing, bronze vanes, FKM elastomers, PTFE lip seals, high-temperature grease-lubricated ball bearings that are isolated from the pumpage and high-temperature gasket-materials. TXV pumps deliver more fluid per revolution than comparably ported gear pumps while their slower operating speeds result in longer service life and reduced maintenance requirements. The TXV’s internal relief valve also protects the pump from pressure buildup.
