316L stainless steel water ring vacuum pump is suitable for pumping gas and steam. Its suction pressure can reach 33 mbar (absolute pressure) (97% vacuum). When transformer oil is used as working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar (absolute pressure) (99.3% vacuum), so it can completely replace the reciprocating vacuum pump. When the vacuum pump works for a long time under the suction pressure close to the limit vacuum, it needs to be connected with the cavitation protection tube to eliminate screaming and protect the pump. As a compressor, the limit pressure is 0.26 MPa (absolute pressure).
2BV series liquid ring vacuum pumps and compressors as a new generation of energy-saving products, their excellent performance and advantages will replace SK, 2SK series water ring vacuum pumps, W, WY, WL series reciprocating vacuum pumps.
316L stainless steel water ring vacuum pump/compressor is mainly used for pumping explosive gases or working in various flammable and explosive environments. Its performance parameters are the same as 2BV2,2BV5 series.
316L stainless steel water ring vacuum pump features:
1. Direct coupling design, easy installation and space saving.
2. The bearings are all Japanese NSK.
3. The standard configuration uses John Crane mechanical seal, which eliminates leakage and is easy to maintain.
4. The pump has a cavitation protection port. When working under the limit pressure, the cavitation protection port opens (or connects with the separator) to ensure the maximum suction effect, eliminate the noise of the cavitation and protect the pump.
5.The 2BV series is made of high-strength aluminum bronze impeller, which improves corrosion resistance and durability. If the liquid flow parts are made of stainless steel, the pump can work in harder conditions.
6. The special flexible exhaust port can avoid overpressure and ensure the best efficiency within its performance range.
7. All motors adopt Y2 series products. The protection level is IP54 or IP55 (IP44 for general purpose) and the insulation level is F (B for general purpose).
8.2BV series water ring vacuum pump can bring all soft sealing parts using PTFE, which can be used in worse environment and has long service life.
9. Stable operation and noise can be reduced to 62 dB.
