ZHAOHAN PUMP WORKS is professional suplier for Siemens and Nash copy liquid ring vacuum pump and compressor. All our pumps are 100% interchangeable with Siemens and NASH both in dimension and performance. Most our client are using our pump to replace their existed Siemens and Nash pump. Some clients are also buying our spare parts for original Siemens pump repair.

Our 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.

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.

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

Max. Suction Capacity: 27-500 m3/h
