Water Ring Vacuum Pump

Water Ring Vacuum Pump

CZPT Co., Ltd is the expert vacuum pump provider.
2BV collection h2o ring vacuum pumps are ideal for pumping the gases and steam. Its suction strain can get to 33mbar (Ab muscles) (i. e. ninety seven % vacuum degree). If the transformer oil is employed as the working liquid, these pumps are known as oil ring vacuum pump and the suction pressure can achieve 6.7mbar (Abs) (i. e. ninety nine % vacuum degree). So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps perform underneath the issue around the limited vacuum for a extended time, it is necessary to few with the cavitation protection pipe in order to get rid of the screaming and protect the pump.
When the compressor is doing work, the maximum strain is .26MPa (Abs). And the greater of discharge pressure, the greater of the electricity of the compressors. So it is necessary that the data of the discharge pressure is provided to choose the proper motor.
2BV2-Ex, 2BV6 collection h2o ring vacuum pumps and compressors are mainly utilised for pumping the explosive gases or perform in the flammable and explosive atmosphere. The specialized parameter of every single variety is the identical as the corresponding kind of the 2BV2 or 2BV5 series goods.
2BV collection stainless metal pumps can be utilized under the situations with greater requirements for the corrosive-evidence or the lustration.
According to the operating scenario, the material of all the parts in which the liquid flows (i. e. Pump casing, pump include, port plate, and impeller)are produced of various stainless steel as bellow:
SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)
The substance of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John CZPT items and the seals materials is optional for FPM or PTFE.

2BV series goods have the characteristics as bellow
· The near-coupled style is handy to put in and can save space.
· The CZPT seals are all employed the John CZPT mechanical seals.
· 2BV sequence items have the cavitation defense port. When they perform beneath the problem near the minimal vacuum, the cavitation defend port opens (or connects with the separator)to get rid of the screaming to safeguard the pump.
· Aluminum bronze impeller is of high depth and putting on well. The erosive-evidence ability of the pump can be enhanced by using it. If the areas exactly where the liquid flows are made of the stainless metal, the pumps can be used below the a lot more rigorous situation.
· The distinctive design of the discharge port can protect the pump from the more than-pressure to make certain the ideal productive functionality in the doing work assortment of the pump.
· The motors are all adopted Y2 collection items. The protection course is IP54 or IP55 (typical is IP44) and the insulation quality is F.
· The bearings are all used the imported goods with manufacturer title of NTN or NSK.
