Water Ring Vacuum Pump  Liquid Ring Vacuum Pump

CZPT Co., Ltd is the professional vacuum pump supplier.

2BV sequence h2o ring vacuum pumps are appropriate for pumping the gases and steam. Its suction pressure can attain 33mbar (Ab muscles) (i. e. 97 % vacuum degree). If the transformer oil is used as the functioning liquid, these pumps are called oil ring vacuum pump and the suction force can attain 6.7mbar (Abdominal muscles) (i. e. ninety nine % vacuum degree). So the oil ring vacuum pumps can change the reciprocated vacuum pumps totally. When the liquid ring vacuum pumps perform below the condition close to the constrained vacuum for a prolonged time, it is necessary to couple with the cavitation security pipe in buy to get rid of the screaming and shield the pump.

When the compressor is doing work, the maximum strain is .26MPa (Abs). And the greater of discharge pressure, the more substantial of the electrical power of the compressors. So it is needed that the info of the discharge strain is presented to pick the proper motor.

2BV2-Ex, 2BV6 sequence water ring vacuum pumps and compressors are mostly utilized for pumping the explosive gases or function in the flammable and explosive setting. The technical parameter of every single variety is the same as the corresponding variety of the 2BV2 or 2BV5 collection products.

2BV series stainless steel pumps can be used under the problems with higher requirements for the corrosive-proof or the lustration.

In accordance to the working circumstance, the substance of all the elements exactly where the liquid flows (i. e. Pump casing, pump include, port plate, and impeller)are manufactured of a variety of stainless steel as bellow:

SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)

The content of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti

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

2BV sequence merchandise have the qualities as bellow

· The shut-coupled design and style is practical to put in and can help save place.

· The CZPT seals are all used the John CZPT mechanical seals.

· 2BV sequence items have the cavitation protection port. When they function beneath the situation close to the restricted vacuum, the cavitation safeguard port opens (or connects with the separator)to get rid of the screaming to defend the pump.

· Aluminum bronze impeller is of higher intensity and sporting properly. The erosive-proof ability of the pump can be improved by employing it. If the parts exactly where the liquid flows are created of the stainless metal, the pumps can be employed below the far more rigorous problem.

· The special layout of the discharge port can defend the pump from the in excess of-stress to guarantee the ideal efficient overall performance in the functioning assortment of the pump.

· The motors are all adopted Y2 series items. The defense course is IP54 or IP55 (typical is IP44) and the insulation grade is F.

· The bearings are all employed the imported products with brand name identify of NTN or NSK.
