Features a coaxial direct-coupled motor and pump structure. Reduces footprint and overall weight (34 kg), eliminating alignment issues and enabling easy installation in compact skid systems.
Equipped with high-grade mechanical shaft seals as standard. Completely eliminates fluid and gas leakage, reducing maintenance demands compared to traditional gland packing seals.
Precision dynamic balancing and optimized liquid ring hydraulics ensure smooth rotation, keeping acoustic noise levels as low as ≤62 dB(A) for quiet indoor and laboratory use.
Specially engineered flexible exhaust ports eliminate over-compression for peak operating efficiency. Integrated cavitation protection line connections shield the pump during limit vacuum runs.
Widely used in hospital vacuum systems, autoclaves, operating rooms, medical suction units, and laboratory vacuum sterilization cabinets.
Provides effective degassing during plastic pellet manufacturing, rubber molding, polyethylene processing, and tire manufacturing lines.
Ideal for vacuum filtration, liquid degassing in bottling plants, dairy processing, vacuum drying, and fruit/vegetable impregnation.
Used for priming centrifugal water pumps in municipal waterworks, groundwater collection, and condenser water box priming in power plants.
The 2BVA2060 delivers a maximum suction capacity of 0.45 m³/min (27 m³/h) and achieves an ultimate limit vacuum pressure of 33 mbar absolute (-0.097 MPa or 97% vacuum level) with a 0.81 kW motor.
When operating near its ultimate vacuum limit (33 mbar abs), the working liquid may vaporize and cause damaging cavitation bubbles. Connecting a cavitation protection line equalizes pressure and prevents internal impeller erosion.
Yes, 2BVA series liquid ring pumps can also function as low-pressure gas compressors, achieving a maximum discharge pressure of up to 0.26 MPa absolute.
We offer dual-frequency motors (380V/50Hz, 440V/60Hz), custom anti-corrosion stainless steel (SS304/SS316L) wet parts, dynamic mechanical seals, and tailored voltage options for global market deployment.
