Blackmer's TXV sliding vane pumps efficiently handle asphaltSeptember 22, 2012
Blackmer's TXV Series sliding vane pumps are designed to meet the challenges of handling asphalt, which is often hot and of varying viscosity. The TXV pumps offer high-volume, low-speed transfer of the material. The key: The pump's sliding vane motor design. It can sustain a high-level performance over a wide range of viscosity.
The pump also offers slow operating speeds and a non-pulsating flow to reduce shear and product agitation, according to a news release from the company. The TXV sliding vane pumps are self-priming and can run dry for short periods of time. The pumps come 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 isolated from the pumpage, and high-temperature gasket-materials, the company reports.
The TXV series pumps have a longer service life and reduced maintenance requirements because of the slower operating speeds. The pump's internal relief valve also protects the pump from pressure buildup. For more information, go to www.blackmer.com. Blackmer is an operating company within Pump Solutions Group (PSG).
