Summary:

2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump. If used as a compressor, its pressure is up to 0.26MPa (absolute pressure). 2BV series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.

2BV2-Ex, 2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series products.

2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.

According to the working situation, the material of all the parts where the liquid flows (i.e. pump casing, pump cover, port plate and impeller) are made of various stainless steel as bellow:The impeller,disc,Pump cover,Pump body.Material can be used

SUS304(0Cr18Ni9)

SUS316(0Cr17Ni12Mo2)

SUS316L(00Cr17Ni14Mo2)

The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti

The mechanical seals are used the John Crane products and the seals material is optional for FPM or PTFE.

 

Main features:

.The close-coupled design is convenient to install and can save space.

.The standard seals are all used the John Crane mechanical seals.

.2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator) to get rid of the screaming to protect the pump.

.Aluminium bronze impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel, the pumps can be used under the more rigorous condition.

.The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the pump.

.The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.

.The bearings are all used the imported products with brand name of NTN or NSK.

.2BV series water ring vacuum pump can achieve flexible sealing parts all of PTFE, which can greatly extend the life of the vacuum pump in harsh conditions

    Note:

     
    1. The performance parameters listed in the table above are obtained under the condition that the saturated medium is 20 ° C saturated air, the working fluid temperature is 15 ° C, and the exhaust pressure is 1013mbar. The performance tolerance is ± 10%.
    2. The flow rate of the working fluid listed in the table is equipped with a gas-water separator. Some of the working fluid is required for circulating use. If the working fluid is not recycled, the actual working fluid flow rate is about the flow rate in the table. 2 times.
    Note: The performance curve is obtained under the condition that the saturated medium is 20 ° C saturated air, the working fluid temperature is 15 ° C, and the exhaust pressure is 1013mba. The performance tolerance is ± 10%. The left side of the figure is the performance curve of the air ejector.
     
     
    Selection example:
     
    ①Design point parameters:
    Inspiratory capacity v = 200m3 / h
    Suction pressure P1 = 200mbar
     
    ②Other parameters are the same as the standard state (see note)
    Select the curve closest to the design point ①
     
    ③ 111V in this example
    Find out the corresponding product model according to the curve number
    (That is, the fixed loan number, but only for the standard type)
    As in this example, the pump type can be found from 111V as
    2BV5111 (non-explosion-proof) or 2BV6111 (explosion-proof)
     

    ④ The water temperature of the water ring vacuum pump has a great impact on its performance, and the performance curve of the water ring vacuum pump is measured at a water temperature of 15 ° C. Therefore, when the water ring vacuum pump is actually selected, the pumping rate of the water ring vacuum pump should be corrected . Please refer to the correction method: water temperature of water ring vacuum pump performance.
