Liquid Ring Vacuum Pump

Liquid Ring Vacuum Pump

CZPT Co., Ltd is the professional vacuum pump provider.
2BV sequence water ring vacuum pumps are ideal for pumping the gases and steam. Its suction force can get to 33mbar (Abs) (i. e. ninety seven % vacuum diploma). If the transformer oil is utilized as the running liquid, these pumps are known as oil ring vacuum pump and the suction stress can attain six.7mbar (Stomach muscles) (i. e. ninety nine % vacuum degree). So the oil ring vacuum pumps can exchange the reciprocated vacuum pumps entirely. When the liquid ring vacuum pumps perform underneath the condition in close proximity to the limited vacuum for a lengthy time, it is essential to pair with the cavitation defense pipe in get to get rid of the screaming and safeguard the pump.

When the compressor is functioning, the optimum stress is .26MPa (Stomach muscles). And the larger of discharge stress, the bigger of the energy of the compressors. So it is needed that the information of the discharge strain is supplied to pick the correct motor.
2BV2-Ex, 2BV6 collection h2o ring vacuum pumps and compressors are mainly utilized for pumping the explosive gases or operate in the flammable and explosive atmosphere. The technical parameter of every single sort is the same as the corresponding kind of the 2BV2 or 2BV5 series products.
2BV collection stainless metal pumps can be used beneath the problems with greater demands for the corrosive-proof or the lustration.

According to the working scenario, the substance of all the areas the place the liquid flows (i. e. Pump casing, pump cover, port plate, and impeller)are created of various stainless metal as bellow:
SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)
The content of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are employed the John CZPT merchandise and the seals materials is optional for FPM or PTFE.

2BV sequence items possess the traits as bellow
· The close-coupled layout is convenient to install and can help save place.
· The CZPT seals are all utilized the John CZPT mechanical seals.
· 2BV series goods have the cavitation protection port. When they perform below the condition close to the limited 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 large depth and donning well. The erosive-evidence potential of the pump can be enhanced by utilizing it. If the elements the place the liquid flows are created of the stainless steel, the pumps can be used below the a lot more demanding situation.
· The special style of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the operating range of the pump.
· The motors are all adopted Y2 series goods. The defense class is IP54 or IP55 (regular is IP44) and the insulation quality is F.
· The bearings are all utilised the imported merchandise with model identify of NTN or NSK.
