CZPT CZPT &lparXihu (West Lake) Dis.&rpar Co&period&comma Ltd is the skilled vacuum pump supplier&time period
2BV series water ring vacuum pumps are suitable for pumping the gases and steam&period Its suction force can achieve 33mbar &lparABS&rpar &lpari&period of time e&period ninety seven &percnt vacuum degree&rpar&period If the transformer oil is employed as the operating liquid&comma these pumps are known as oil ring vacuum pump and the suction force can get to 6&period7mbar &lparABS&rpar &lpari&interval e&interval ninety nine &percnt vacuum degree&rpar&period So the oil ring vacuum pumps can change the reciprocated vacuum pumps fully&time period When the liquid ring vacuum pumps function under the condition in close proximity to the constrained vacuum for a lengthy time&comma it is necessary to couple with the cavitation safety pipe in order to get rid of the screaming and shield the pump&period

When the compressor is operating&comma the optimum pressure is &period26MPa &lparABS&rpar&period And the higher of discharge force&comma the larger of the power of the compressors&period So it is needed that the information of the discharge stress is supplied to choose the suitable motor&period
2BV2-Ex&comma 2BV6 collection drinking water ring vacuum pumps and compressors are largely used for pumping the explosive gases or work in the flammable and explosive setting&time period The technological parameter of every single sort is the exact same as the corresponding type of the 2BV2 or 2BV5 sequence products&period of time
2BV sequence stainless metal pumps can be utilized underneath the conditions with increased requirements for the corrosive-evidence or the lustration&time period

In accordance to the functioning circumstance&comma the material of all the components in which the liquid flows &lpari&time period e&period of time Pump casing&comma pump go over&comma port plate&comma and impeller&rparare made of different stainless metal as bellow&colon
