Aitcool ARV-8 Rotary Vane Vaccuum Pump

The ARV-8 is a top-of-the-range, industrial vacuum pump. It has a range of applications from vacuum ovens, to rotary evaporators, to short path distillation.

Rotary vane - also known as sliding vane pumps - are designed to pump for extended periods of time and are renowned for their ability to pull down to a deep vacuum. They are extremely reliable and work via a positive displacement principle, essentially trapping the fluid/vapour as it is pulled into the inlet pipe, trapping it in-between the vanes on the inside cam and forcing it through the outlet/discharge pipe.

Rotary vane pumps are a versatile solution as they can handle low to medium viscosity fluids and non-lubricating fluids because there is no metal on metal contact within the pump. This additionally means that the pump can maintain a high performance and has a very long life span. Where the rotary vane truly excels however, is handling low viscosity liquids, such as propane, butane, solvents and alcohols.
