The description of experimental unit for research of oil-free scroll vacuum pimps is presented. The makes possible to measure main characteristics of scroll pumps, i.e. pump speed, ultimate pressure, input power, vibration, noise level, casing temperature, temperature of gas at the inlet and the outlet. All parameters can be measured in the pressure range from the ultimate pressure up to the pressure close to atmospheric pressure. Some research characteristics of commercial scroll pumps are presented.
