Models 2BV and SK are single stage liquid ring vacuum pumps.
Model 2SK is double stages liquid ring vacuum pump.
The liquid-ring vacuum pump compresses gas by rotating a vaned impeller within a cylindrical casing. Liquid (usually water) is fed into the pump, and by centrifugal acceleration, forms a moving cylindrical ring against the inside of the casing. This liquid ring creates a series of seals in the space between the impeller vanes, which form compression chambers. The eccentricity between the impeller's axis of rotation and the casing geometric axis results in a cyclic variation of the volume enclosed by the vanes and the ring.
Gas, often air, is drawn into the pump through an inlet port in the end of the casing. The gas is trapped in the compression chambers formed by the impeller vanes and the liquid ring. The reduction in volume caused by the impeller rotation compresses the gas, which reports to the discharge port in the end of the casing.
Compressed gas on discharge of pump contains certain amount of working liquid which is usually removed in vapor-liquid separator.
Applications:
Single stage or two stage liquid ring vacuum pumps are the ideal for specific, humid, dirty or high capacity applications in heavy industries,a selection of which can be found below.
The 2BV, SK and 2SK series are the workhorses: proven, strong and reliable machines that deliver utility or process vacuum.
2BV SK and 2SK series pumps are therefore suitable for use in the following industry:
· General manufacturing · Metalwork industry
· Food processing · Petroleum industry
· Paint industry· Mining
· Chemical industry· Oil and gas
· Paper and allied products · Plastics
