2BV5-110 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 6.7mbar (absolute pressure) (99.3% vacuum degree), so it can completely replace reciprocating vacuum pump. When the vacuum pump works for a long time under the suction pressure close to the limit vacuum, it needs to connect the cavitation protection pipe to eliminate the scream and protect the pump. As a compressor, the limit pressure is 0.26mpa (absolute pressure).
As a new generation of energy-saving products, the outstanding performance and advantages of 2bv5-110 water ring vacuum pump and compressor will replace SK, 2SK series water ring vacuum pump.
2BV5-110 water ring vacuum pump features:
1. Closed design, convenient installation and space saving.
2. All bearings are imported products of NTN or NSK brand
3. All standard seals are John Crane mechanical seals, eliminating leakage and easy to maintain
4.2 bv series products have cavitation protection port. When they operate near the limit vacuum, the cavitation protection port opens (or is connected to the separator) to eliminate squeaks and protect the pump.
5. Aluminum bronze impeller has high strength and wear resistance. It can improve the corrosion resistance of the pump. If the liquid flow part is made of stainless steel, the pump can be used under more stringent conditions.
6. The unique design of the discharge outlet can protect the pump from overpressure, so as to ensure the best efficient performance within the working range of 2BV vacuum pump.
7. All motors are Y2 series products. The protection grade is IP54 or IP55 (standard is IP44), and the insulation grade is f (standard is b).
8.2 bv water ring vacuum pump can achieve all PTFE flexible seals, which can greatly extend the working life under higher requirements
9. The operation is stable and the noise can be as low as 62 dB.
