2BV Liquid Ring Vacuum Pump

2BV Liquid Ring Vacuum Pump

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

2BV collection drinking water ring vacuum pumps are ideal for pumping the gases and steam. Its suction strain can attain 33mbar (Stomach muscles) (i. e. ninety seven % vacuum diploma). If the transformer oil is used as the functioning liquid, these pumps are known as oil ring vacuum pump and the suction strain can reach six.7mbar (Stomach muscles) (i. e. ninety nine % vacuum diploma). So the oil ring vacuum pumps can change the reciprocated vacuum pumps totally. When the liquid ring vacuum pumps function beneath the situation in close proximity to the minimal vacuum for a extended time, it is essential to few with the cavitation security pipe in get to get rid of the screaming and shield the pump.

When the compressor is doing work, the highest strain is .26MPa (Abs). And the larger of discharge strain, the bigger of the power of the compressors. So it is essential that the knowledge of the discharge force is provided to pick the proper motor.

2BV2-Ex, 2BV6 series h2o ring vacuum pumps and compressors are largely used for pumping the explosive gases or operate in the flammable and explosive atmosphere. The specialized parameter of each and every sort is the identical as the corresponding kind of the 2BV2 or 2BV5 collection items.

2BV collection stainless metal pumps can be employed underneath the problems with larger specifications for the corrosive-evidence or the lustration.

According to the doing work situation, the content of all the components in which the liquid flows (i. e. Pump casing, pump include, port plate, and impeller)are produced 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 used the John CZPT products and the seals materials is optional for FPM or PTFE.

2BV sequence items have the attributes as bellow

· The near-coupled design is hassle-free to put in and can conserve place.

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

· 2BV collection items have the cavitation defense port. When they work below the issue around the restricted vacuum, the cavitation safeguard port opens (or connects with the separator)to get rid of the screaming to safeguard the pump.

· Aluminum bronze impeller is of large intensity and sporting well. The erosive-evidence ability of the pump can be improved by using it. If the areas where the liquid flows are created of the stainless steel, the pumps can be employed beneath the far more rigorous problem.

· The exclusive style of the discharge port can protect the pump from the in excess of-pressure to ensure the ideal effective functionality in the doing work selection of the pump.

· The motors are all adopted Y2 collection items. The security course is IP54 or IP55 (normal is IP44) and the insulation grade is F.

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