Vacuum Pump: 2BV Series Liquid Ring Vacuum Pump

The SKA(2BV) series vacuum pumps are suitable for extracting gases and water vapor, with an inlet pressure reaching 33 mbar absolute pressure (97% vacuum). When the vacuum pump operates for extended periods at inlet pressures below 80 mbar, a cavitation protection pipe should be connected to protect the pump. With the addition of an atmospheric ejector, the inlet pressure can reach 10 mbar, and the ejector can be directly mounted on the vacuum pump. When used as a compressor, the pressure can be as high as 0.26 MPa (absolute pressure). Water ring vacuum pumps and compressors are widely used in fields such as petrochemicals, pharmaceuticals, food, and sugar industries. Due to the isothermal nature of the gas compression process during operation, there is less risk when compressing or extracting flammable and explosive gases, which makes their application even broader. **Structure and Features** - Coaxial direct connection design of the pump saves space and facilitates installation. - Mechanical seals are used as standard configuration, eliminating leaks and simplifying maintenance. - Smooth operation with noise levels as low as 62 decibels. - Uniform corrosion-resistant design, with bronze impellers enhancing the pump's corrosion resistance; stainless steel materials are more suitable for harsher applications. - Unique flexible exhaust port design prevents over-compression, ensuring the efficiency of SKA within its performance range. **Technical Parameters** | Curve Number | Model | Air Volume (m³/min) | Ultimate Vacuum (MPa) | Motor Power (kw) | Pump Speed (R.P.m) | Working Liquid Flow (L/min) | Noise (A) | Weight (kg) | |--------------|-------------|---------------------|------------------------|------------------|---------------------|------------------------------|-----------|-------------| | 60V | SKA-2060 | 0.45 | -0.097 | 0.81 | 2880 | 2 | 62 | 37 | | 61V | SKA-2061 | 0.86 | -0.097 | 1.45 | 2880 | 2 | 65 | 41 | | 70V | SKA-2070 | 1.33 | -0.097 | 2.35 | 2850 | 2.5 | 66 | 66 | | 71V | SKA-2071 | 1.83 | -0.097 | 3.85 | 2860 | 4.2 | 72 | 85 | | 110V | SKA-5110 | 2.75 | -0.097 | 4 | 1450 | 6.7 | 63 | 120 | | 111V | SKA-5111 | 3.83 | -0.097 | 5.5 | 1450 | 8.3 | 68 | 150 | | 121V | SKA-5121 | 4.66 | -0.097 | 7.5 | 1450 | 10 | 69 | 210 | | 131V | SKA-5131 | 6.66 | -0.097 | 11 | 1430 | 15 | 73 | 280 | | 161V | SKA-5161 | 8.33 | -0.097 | 15 | 970 | 20 | 74 | 390 | | 110V | SKA-6110 | 2.75 | -0.097 | 4 | 1450 | 6.7 | 63 | | | 111V | SKA-6111 | 3.83 | -0.097 | 5.5 | 1450 | 8.3 | 68 | | | 121V | SKA-6121 | 4.66 | -0.097 | 7.5 | 1450 | 10 | 69 | | | 131V | SKA-6131 | 6.66 | -0.097 | 11 | 1430 | 15 | 73 | | | 161V | SKA-6161 | 8.33 | -0.097 | 15 | 970 | 20 | 74 | |
