The Bombas Trief BAL-2R vane pump is a positive displacement pump designed for pumping most medium and low viscosity fluids free of solids. The BAL 2R rotary pump is robust, quiet and highly efficient; it is particularly excellent at handling fuels and oils up to 250°C. Supplied as standard with two mechanical seals, this vane pump has added protection when pumping high temperature oils and fuels. Frequent uses of this positive displacement sliding vane pump include edible oil refineries, oil refineries, gas depots, fuel transfer, packaging plants, animal feed plants and oil presses.

FAQs

Rectangular shaped vanes are mounted into slots on a rotor that turns inside the asymmetrical pump casing. As the rotor turns, the asymmetrical casing causes the vanes to move in and out of the slots to touch the casing walls and trap the fluid between this and the rotor. This mechanism draws the fluid round until it is forced out of the discharge port.

Rotary vane pumps are a popular and efficient solution for the transfer of clean, low to medium viscosity fluids and fuels at a range of temperatures. They are generally not suited to high pressure applications as it can cause the vanes to struggle to maintain contact with the casing walls.

Yes. Being able to operate in both directions makes vane pumps ideal for tank to tank transfer as well as returning excess liquid out of the pipework when transfer is complete.

No. The close tolerances between the vanes and casing mean that pumping solids will result in any solids jamming the vanes.

Yes, vane pumps have excellent suction capabilities without need for a manual priming device.

Yes. Whilst popular applications are often lubricating fluids such as fuels and oils, the lack of metal to metal contact during the operation of a vane pump means they can also handle thin fluids that provide no lubrication without wear.
