Vane PumpThese pumps have a number of vanes that are free to slide into or out of slots in the pump rotor. When the pump driver turns the rotor, centrifugal force, push rods, and/or pressurized fluid causes the vanes to move outward in their slots and bear against the inner bore of the pump casing forming pumping chambers.

As the rotor revolves, fluid flows into the area between the vanes (pumping cambers) when they pass the suction port. This fluid is transported around the pump casing until the discharge port is reached. At this point the fluid is squeezed out into the discharge piping.

TX/TXD Series Sliding Vane Pumps

Applications – Clean, lubricating liquids for petroleum products: fuel oil, diesel, kerosene, gasoline, avgas, jet fuel and light lube oils.

Features and Benefits

  • Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
  • Excellent self-priming and dry-run capabilities
  • Dual-ended shaft on 2-, 2.5- and 3-inch models simplifies installation
  • Blackmer mechanical seal and ball-bearing construction provide maximum reliability
  • Symmetrical bearing support assures even loading and wear for long life
  • Adjustable relief valve protects pump against excessive pressures
  • External ball-bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
  • Easy maintenance: vanes can be easily replaced — without removing pump from truck
