2BV5131 Water Ring Vacuum Pump

Greentech International (Zhangqiu) Co., Ltd is the professional vacuum pump
supplier.
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).
If the transformer oil is used as the operating liquid, these pumps are called
oil ring vacuum pump and the suction pressure can reach 6.7mbar (ABS) (i. e. 99
% vacuum degree). So the oil ring vacuum pumps can replace the reciprocated
vacuum pumps completely. 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.
When the compressor is working, the maximum pressure is 0.26MPa (ABS). And the
higher of discharge pressure, the larger of the power of the compressors. So it
is necessary that the data of the discharge pressure is provided to choose the
proper motor.
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:
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.

2BV series products possess the characteristics as bellow
· 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.
· Aluminum 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.
