CZPT CZPT &lparXihu (West Lake) Dis.&rpar Co&interval&comma Ltd is the professional vacuum pump provider&period of time
2BV collection h2o ring vacuum pumps are suitable for pumping the gases and steam&period Its suction stress can achieve 33mbar &lparABS&rpar &lpari&interval e&interval ninety seven &percnt vacuum diploma&rpar&interval If the transformer oil is utilised as the functioning liquid&comma these pumps are called oil ring vacuum pump and the suction strain can reach 6&period7mbar &lparABS&rpar &lpari&time period e&interval ninety nine &percnt vacuum degree&rpar&period So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps totally&period When the liquid ring vacuum pumps perform beneath the condition near the restricted vacuum for a extended time&comma it is needed to few with the cavitation safety pipe in purchase to get rid of the screaming and defend the pump&time period
When the compressor is doing work&comma the highest strain is &period26MPa &lparABS&rpar&interval And the larger of discharge pressure&comma the bigger of the energy of the compressors&period So it is needed that the info of the discharge pressure is supplied to choose the proper motor&interval
2BV2-Ex&comma 2BV6 sequence water ring vacuum pumps and compressors are primarily employed for pumping the explosive gases or function in the flammable and explosive setting&period The specialized parameter of every variety is the identical as the corresponding kind of the 2BV2 or 2BV5 collection items&interval
2BV sequence stainless metal pumps can be utilized under the circumstances with greater needs for the corrosive-evidence or the lustration&interval
In accordance to the functioning circumstance&comma the substance of all the elements in which the liquid flows &lpari&interval e&period of time Pump casing&comma pump include&comma port plate&comma and impeller&rparare created of different stainless metal as bellow&colon

The materials of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are utilised the John CZPT goods and the seals substance is optional for FPM or PTFE&period of time

2BV collection items have the attributes as bellow
· The close-coupled layout is practical to set up and can preserve room&period
· The CZPT seals are all utilized the John CZPT mechanical seals&interval
· 2BV series items have the cavitation security port&time period When they function below the situation around the minimal vacuum&comma the cavitation defend port opens &lparor connects with the separator&rparto get rid of the screaming to protect the pump&interval
· Aluminum bronze impeller is of large depth and donning well&interval The erosive-proof potential of the pump can be enhanced by using it&period If the components the place the liquid flows are manufactured of the stainless metal&comma the pumps can be utilised beneath the a lot more demanding situation&time period
· The exclusive style of the discharge port can safeguard the pump from the over-stress to guarantee the ideal efficient functionality in the doing work range of the pump&interval
· The motors are all adopted Y2 sequence merchandise&interval The security class is IP54 or IP55 &lparnormal is IP44&rpar and the insulation grade is F&period of time
· The bearings are all employed the imported goods with model name of NTN or NSK&time period
