2BV5121 Liquid Ring Vacuum Pump

2BV5121 Liquid Ring Vacuum Pump

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

2BV collection water ring vacuum pumps are suited for pumping the gases and steam. Its suction stress can get to 33mbar (Ab muscles) (i. e. 97 % vacuum diploma). If the transformer oil is used as the working liquid, these pumps are named oil ring vacuum pump and the suction force can get to 6.7mbar (Ab muscles) (i. e. 99 % vacuum diploma). So the oil ring vacuum pumps can substitute the reciprocated vacuum pumps entirely. When the liquid ring vacuum pumps perform below the situation near the restricted vacuum for a extended time, it is needed to pair with the cavitation protection pipe in purchase to get rid of the screaming and shield the pump.

When the compressor is functioning, the maximum stress is .26MPa (Abdominal muscles). And the increased of discharge pressure, the larger of the energy of the compressors. So it is needed that the information of the discharge strain is provided to choose the correct motor.

2BV2-Ex, 2BV6 sequence drinking water ring vacuum pumps and compressors are mostly utilised for pumping the explosive gases or work in the flammable and explosive setting. The complex parameter of each and every type is the very same as the corresponding sort of the 2BV2 or 2BV5 sequence items.

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

According to the functioning circumstance, the material of all the components the place the liquid flows (i. e. Pump casing, pump cover, port plate, and impeller)are made of different stainless metal as bellow:

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

The substance of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti

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

2BV sequence products have the traits as bellow

· The near-coupled design and style is practical to install and can preserve place.

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

· 2BV series merchandise have the cavitation defense port. When they function underneath the problem in close proximity to the constrained vacuum, the cavitation safeguard port opens (or connects with the separator)to get rid of the screaming to protect the pump.

· Aluminum bronze impeller is of substantial intensity and donning nicely. The erosive-evidence capability of the pump can be improved by utilizing it. If the components in which the liquid flows are created of the stainless metal, the pumps can be employed underneath the much more arduous issue.

· The unique layout of the discharge port can shield the pump from the in excess of-pressure to make sure the very best effective performance in the functioning selection of the pump.

· The motors are all adopted Y2 sequence goods. The security class is IP54 or IP55 (normal is IP44) and the insulation quality is F.

· The bearings are all utilized the imported merchandise with brand name title of NTN or NSK.
