CZPT CZPT &lparXihu (West Lake) Dis.&rpar Co&period of time&comma Ltd is the professional vacuum pump provider&time period
2BV series h2o ring vacuum pumps are suited for pumping the gases and steam&period of time Its suction force can reach 33mbar &lparABS&rpar &lpari&period of time e&interval 97 &percnt vacuum diploma&rpar&period If the transformer oil is utilised as the working liquid&comma these pumps are known as oil ring vacuum pump and the suction force can reach six&period7mbar &lparABS&rpar &lpari&period e&time period 99 &percnt vacuum degree&rpar&interval So the oil ring vacuum pumps can replace the reciprocated vacuum pumps fully&time period When the liquid ring vacuum pumps function underneath the problem close to the constrained vacuum for a lengthy time&comma it is necessary to few with the cavitation safety pipe in buy to get rid of the screaming and shield the pump&period of time

When the compressor is working&comma the optimum pressure is &period26MPa &lparABS&rpar&time period And the higher of discharge force&comma the greater of the electrical power of the compressors&period So it is necessary that the information of the discharge force is supplied to pick the appropriate motor&period

2BV2-Ex&comma 2BV6 series water ring vacuum pumps and compressors are primarily utilized for pumping the explosive gases or operate in the flammable and explosive atmosphere&period The complex parameter of each and every variety is the exact same as the corresponding sort of the 2BV2 or 2BV5 collection products&period
2BV sequence stainless metal pumps can be utilised beneath the situations with increased specifications for the corrosive-evidence or the lustration&period of time

In accordance to the operating situation&comma the content of all the elements where the liquid flows &lpari&time period e&period Pump casing&comma pump protect&comma port plate&comma and impeller&rparare manufactured of different stainless steel as bellow&colon

The mechanical seals are utilised the John CZPT items and the seals substance is optional for FPM or PTFE&time period

2BV collection goods possess the traits as bellow
· The near-coupled design is practical to install and can conserve space&period of time
· The CZPT seals are all used the John CZPT mechanical seals&interval
· 2BV series items have the cavitation safety port&period When they operate beneath the issue in close proximity to the minimal vacuum&comma the cavitation safeguard port opens &lparor connects with the separator&rparto get rid of the screaming to protect the pump&interval

· Aluminum bronze impeller is of high intensity and wearing properly&interval The erosive-proof capacity of the pump can be improved by employing it&period If the elements exactly where the liquid flows are made of the stainless steel&comma the pumps can be utilised beneath the far more rigorous situation&period of time
· The unique style of the discharge port can defend the pump from the more than-force to guarantee the greatest efficient efficiency in the functioning range of the pump&period of time
· The motors are all adopted Y2 series merchandise&interval The protection class is IP54 or IP55 &lparnormal is IP44&rpar and the insulation quality is F&time period
· The bearings are all used the imported products with manufacturer identify of NTN or NSK&period
