The VVN 1-3 liquid ring vacuum pump is designed to create vacuum in closed industrial equipment and process systems. It is suitable for evacuating air, gases and gas-vapor mixtures that are non-aggressive to the materials of the pump's wetted parts.
The VVN 1-3 operates using the liquid-ring principle. During operation, the rotating impeller forms a liquid ring inside the pump casing, providing continuous suction and compression of the gaseous medium. The pump can be used in chemical, oil and gas, pulp and paper, food processing and other industrial applications.
The nominal capacity is 0.056 m³/s (approximately 3.33 m³/min). The pump unit is equipped with a 7.5 kW electric motor operating at 1500 rpm. Maximum pump power consumption is 6.15 kW, while maximum operating water consumption is 0.42 m³/h.
