HSK liquid-ring vacuum pump is an energy-saving product developed by our company, and is used to pump gas which carries no solids undissolved or just slightly dissolved in working liquid, to form vacuum and pressure in the closed container.The characteristics of this series product are as followings:
﹒Single stage and end suction structure, axial gas suction and discharge, being simple in structure and convenient for maintenance.
﹒As the result of the flexible valve provided in the outlet to adjust the discharge angles, the pump can work efficiently at different suction conditions.
﹒Using an automatic discharge valve, the liquid level can be controlled well to prevent over-load start-up.
﹒The rotating parts of the pump do not contact each other in the working chamber. Axial and radial load is borne by different bearings, being Stable, safe and reliable.
﹒There is observation hole on the side cover, pump’s corrosive and scaling conditions can be observed through the hole, it is easy to maintain.
﹒The working process is close to isothermal compression, particularly suitable for the delivery of flammable and explosive gases.
﹒There are packing seal and mechanical seal two kinds of structures to meet the needs of the different seals.
﹒The impeller and shaft adopt thermal interference fit, with reliable performanceand smooth operation.
﹒By changing materials of the wetted parts in contact with the medium, the pumps can transfer the corrosive gases or meet the anti-corrosion requirements under the working condition with corrosive liquids as working fluid.
