Bơm Chân Không 2BV Series
Introductions:
2BV series Liquid ring vacuum pumps are suitable for pumping 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, we will add our cavitations protection pipe to get rid of the screaming and protect the pump.
When the compressors work, the maximum pressure is 0.26MPa(abs). And the discharge pressure is higher, the power is bigger. So it is necessary to get the data of the discharge pressure is to choose the proper motor.
2BV series liquid 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 Liquid 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.

Advantages:
The close-coupled design is convenient to install and can save space.
The standard seals are all used the John Crane or Burgman mechanical seals.
2BV series products have the cavitations protection port. When they work under the condition near the limited vacuum, the cavitations 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
Comparing with the SK, 2SK, SZ water ring vacuum pumps, the 2BV series products has more advantages:
