2bv Water Ring Vacuum Pump 

2BV water ring vacuum pump:

2BV water ring vacuum pump is suitable to pump gas and water vapor with suction pressure up to 33mbar absolute pressure (97% vacuum).

When using transformer oil as the working fluid (called the oil ring vacuum pump), the suction pressure can reach 6.7mbar absolute pressure (99.3% vacuum), which can completely replace the reciprocating vacuum pump.

When the liquid ring vacuum pump works for a long time under the suction pressure approaching the limit vacuum, the cavitation protection tube should be connected to protect the pump and eliminate the cavitation sound.

When it is used as a compressor, the maximum pressure is 0.26mpa (absolute pressure).

When used as a compressor, 2BV pump power will increase with the increase of exhaust pressure.

Please indicate the exhaust pressure to select the appropriate motor power when ordering.

As a new generation of energy-saving products, 2BV water ring vacuum pump will completely replace SK, 2SK series water ring vacuum pump and W, WY, WL series reciprocating vacuum pump with excellent performance and many advantages.

2BV2-EX, 2BV6 series water-ring vacuum pumps/compressors are mainly used to pump the explosive gas and work in various flammable and explosive environments, with the same performance parameters as the corresponding models of 2BV2, 2BV5 series.

2BV series stainless steel vacuum pumps can be used in a variety of occasions where corrosion resistance is high and cleanliness is high.

SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2) and other stainless steel materials can be used for all the overflow components of 2BV series stainless steel vacuum pump under working conditions.

The pump shaft material is 2Cr13 or 0Cr18Ni12Mo2Ti

2BV type water ring vacuum pump mechanical seal USES the import product, the seal can use the fluorine rubber or the polytetrafluoroethylene.

Compared with domestic water ring vacuum pumps of the same type such as SK, 2SK and SZ, it has the following characteristics:

2BV water ring vacuum pump is with coaxial direct connection design and saves space and it is easy to install.

2BV water ring vacuum pumps all adopt imported mechanical seals as standard configuration.

all the 2BV water ring vacuum pumps are equipped with cavitation protection tube interfaces.

If working under the ultimate pressure, opening the cavitation protection tube interface (or connecting with the separator) can eliminate cavitation sound and protect the pump under the condition of ensuring the suction effect to the maximum extent.

aluminum bronze impeller has high strength and durability and has improved the corrosion resistance of 2BV water ring vacuum pump.

If the flow components using stainless steel material can work in a more demanding environment.

a unique flexible vent design that does not produce over-compression ensures the best efficiency of the 2BV water ring vacuum pump within its performance range.

all use Y2 series motors with IP54 and IP55 protection grades (generally IP44)

·2BV water ring vacuum pumps all adopt NTN or NSK imported bearings
