The pump is designed for pumping the liquid form of fuels with a low boiling point, which remain as a gas at ambient temperature, and whose vapor pressure in the tank is less than 0.8 MPa (8 bar). Guarantees the application of a constant pressure of the inlet gas, in an adjustable amount in the range of 0.8-2.2 MPa (8-22 bar) for aerosol can gasification devices .
