Liquid Ring Vacuum Pump

CZPT CZPT &lparXihu (West Lake) Dis.&rpar Co&interval&comma Ltd is the skilled vacuum pump provider&period
2BV collection h2o ring vacuum pumps are suited for pumping the gases and steam&period of time Its suction pressure can reach 33mbar &lparABS&rpar &lpari&interval e&interval 97 &percnt vacuum diploma&rpar&period of time If the transformer oil is used as the running liquid&comma these pumps are called oil ring vacuum pump and the suction strain can achieve six&period7mbar &lparABS&rpar &lpari&period of time e&period ninety nine &percnt vacuum degree&rpar&time period So the oil ring vacuum pumps can replace the reciprocated vacuum pumps fully&period When the liquid ring vacuum pumps function underneath the situation close to the minimal vacuum for a extended time&comma it is required to few with the cavitation safety pipe in buy to get rid of the screaming and safeguard the pump&period of time

When the compressor is functioning&comma the maximum strain is &period26MPa &lparABS&rpar&period And the greater of discharge stress&comma the greater of the power of the compressors&interval So it is required that the info of the discharge stress is supplied to pick the correct motor&period
2BV2-Ex&comma 2BV6 sequence drinking water ring vacuum pumps and compressors are mostly utilized for pumping the explosive gases or operate in the flammable and explosive atmosphere&period The technical parameter of every single kind is the very same as the corresponding type of the 2BV2 or 2BV5 series merchandise&period
2BV sequence stainless metal pumps can be used below the conditions with higher needs for the corrosive-proof or the lustration&period

In accordance to the operating predicament&comma the content of all the parts in which the liquid flows &lpari&period e&interval Pump casing&comma pump include&comma port plate&comma and impeller&rparare made of different stainless metal as bellow&colon
SUS304 &lpar0Cr18Ni9&rpar&comma SUS316 &lpar0Cr17Ni12Mo2&rpar&comma SUS316L &lpar00Cr17Ni14Mo2&rpar
The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John CZPT items and the seals material is optional for FPM or PTFE&period of time

2BV series products possess the attributes as bellow
· The near-coupled design is handy to install and can preserve space&period of time
· The CZPT seals are all used the John CZPT mechanical seals&time period
· 2BV sequence items have the cavitation security port&period When they perform below the issue around the constrained vacuum&comma the cavitation shield port opens &lparor connects with the separator&rparto get rid of the screaming to safeguard the pump&time period

· Aluminum bronze impeller is of large intensity and donning properly&period of time The erosive-evidence capacity of the pump can be enhanced by utilizing it&time period If the components exactly where the liquid flows are manufactured of the stainless steel&comma the pumps can be used beneath the much more rigorous condition&time period
· The exclusive layout of the discharge port can safeguard the pump from the more than-stress to make certain the greatest productive performance in the operating range of the pump&period of time
· The motors are all adopted Y2 series merchandise&time period The security class is IP54 or IP55 &lparnormal is IP44&rpar and the insulation quality is F&period of time
· The bearings are all utilized the imported goods with brand name name of NTN or NSK&period
