Z-2008 gas pump is meant to be used for pumping propellant gases with a low boiling point in a liquid form, which in the temperature of surroundings remain in a gas form, and the vapour pressure of which in the container is lower than 0.8 MPa (8 bar). It ensures providing the constant supply pressure of gas in the regulated range of 0.8 2.2 MPa (8 22 bar) for gas fillers. By means of maintaining the constant determined pressure of a liquid form, it prevents the cavitation (creating gas cavities resulting from evaporation) of liquid in the installation of the dosing device. All kinds of gas which can be liquefied and used as aerosol propellant may be pumped, e.g. propane, butane, DME, etc.
