Hunan water ring vacuum pump manufacturers supply 2BV water ring vacuum pump, direct design, machine ..

2BV Series ring vacuum pumps suitable for pumping gas and steam, water pressure can reach 33mmbar absolute pressure (97% vacuum). When the transformer oil as the working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7mbar absolute pressure (99.3% vacuum), can completely replace the reciprocating pumps. When approaching ultimate vacuum pump suction pressure long-term work, should join cavitation protection tube to protect the pump. As a compressor, its greatest pressure to 0.26MPa (absolute pressure). 2BV Series ring vacuum pumps, as a new generation of energy-saving products, with excellent performance and its many advantages will replace with the performance of SK, 2SK, W, WY, WL series water ring vacuum pumps, reciprocating pumps. 2BV2-Ex, 2BV6 series water ring vacuum pump / compressor is mainly used for pumping explosive gases, and work in all kinds of flammable and explosive environment, its performance parameters and 2BV2,2BV5 series. Main features:? Pump Direct design, space-saving, easy to install, easy maintenance. ? All imported bearings. ? All mechanical seals as standard, eliminating leakage, easy maintenance. ? They all have the cavitation protection port, such as working under extreme pressure to open the cavitation protection port (or the splitter is connected) can eliminate acoustic cavitation ensure maximum suction effect in the case, and the pump protection. ? 2BV comes standard with a full range of aluminum bronze impeller, high strength, durability, and improve the corrosion resistance of the pump. As flow components made of stainless steel, it can work in harsher environments. ? Unique flexible exhaust port design, without excessive compression, ensuring 2BV efficiency within its optimum performance range. ? All using Y2 series motor, protection class IP54, IP55 (common to IP44), insulation class F insulation (Class B ordinary insulation)? 2BV series water ring vacuum pump can achieve all of the PTFE flexible seal, which can greatly extend the vacuum pump in more demanding conditions of life. ? Run smoothly, the noise can be as low as 62 db.
