Liquid Ring Vacuum Pump

CZPT Co., Ltd is the expert vacuum pump provider.
2BV collection h2o ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can get to 33mbar (Ab muscles) (i. e. ninety seven % vacuum diploma). If the transformer oil is utilized as the working liquid, these pumps are referred to as oil ring vacuum pump and the suction strain can attain six.7mbar (Stomach muscles) (i. e. 99 % vacuum diploma). So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps fully. When the liquid ring vacuum pumps function below the issue in close proximity to the restricted vacuum for a prolonged time, it is needed to few with the cavitation protection pipe in purchase to get rid of the screaming and shield the pump.

When the compressor is doing work, the maximum stress is .26MPa (Ab muscles). And the higher of discharge force, the greater of the electrical power of the compressors. So it is needed that the info of the discharge pressure is presented to choose the appropriate motor.
2BV2-Ex, 2BV6 series drinking water ring vacuum pumps and compressors are mostly utilised for pumping the explosive gases or perform in the flammable and explosive atmosphere. The complex parameter of each variety is the very same as the corresponding kind of the 2BV2 or 2BV5 series merchandise.
2BV sequence stainless metal pumps can be utilised below the problems with higher needs for the corrosive-proof or the lustration.

According to the operating situation, the materials of all the elements the place the liquid flows (i. e. Pump casing, pump go over, port plate, and impeller)are created of numerous stainless steel as bellow:
SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)
The substance of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are employed the John CZPT items and the seals substance is optional for FPM or PTFE.

2BV collection merchandise possess the characteristics as bellow
· The close-coupled layout is practical to install and can save area.
· The CZPT seals are all employed the John CZPT mechanical seals.
· 2BV sequence items have the cavitation safety port. When they work below the problem in close proximity to the limited vacuum, the cavitation shield port opens (or connects with the separator)to get rid of the screaming to protect the pump.

· Aluminum bronze impeller is of high intensity and sporting nicely. The erosive-evidence potential of the pump can be enhanced by employing it. If the components where the liquid flows are created of the stainless steel, the pumps can be utilized underneath the a lot more arduous situation.
· The special design and style of the discharge port can shield the pump from the in excess of-pressure to ensure the best productive performance in the operating selection of the pump.
· The motors are all adopted Y2 sequence merchandise. The safety class is IP54 or IP55 (regular is IP44) and the insulation quality is F.
· The bearings are all used the imported items with model title of NTN or NSK.
