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

2BV sequence water ring vacuum pumps are suited for pumping the gases and steam. Its suction force can reach 33mbar (Abs) (i. e. 97 % vacuum degree). If the transformer oil is utilized as the operating liquid, these pumps are named oil ring vacuum pump and the suction strain can achieve six.7mbar (Ab muscles) (i. e. 99 % vacuum diploma). So the oil ring vacuum pumps can change the reciprocated vacuum pumps fully. When the liquid ring vacuum pumps perform under the problem in close proximity to the constrained vacuum for a prolonged time, it is essential to pair with the cavitation security pipe in purchase to get rid of the screaming and safeguard the pump.

When the compressor is operating, the optimum pressure is .26MPa (Abdominal muscles). And the larger of discharge force, the greater of the power of the compressors. So it is needed that the info of the discharge stress is presented to choose the suitable motor.
2BV2-Ex, 2BV6 sequence h2o ring vacuum pumps and compressors are mostly utilized for pumping the explosive gases or operate in the flammable and explosive setting. The specialized parameter of each variety is the very same as the corresponding type of the 2BV2 or 2BV5 sequence products.
2BV series stainless metal pumps can be utilized under the conditions with increased needs for the corrosive-evidence or the lustration.

According to the operating situation, the materials of all the areas in which the liquid flows (i. e. Pump casing, pump cover, port plate, and impeller)are created of various stainless steel as bellow:
SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2)
The content of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John CZPT goods and the seals material is optional for FPM or PTFE.

2BV series items have the qualities as bellow
· The shut-coupled style is handy to install and can conserve place.
· The CZPT seals are all employed the John CZPT mechanical seals.
· 2BV series goods have the cavitation safety port. When they function beneath the condition in close proximity to the minimal 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 higher depth and putting on properly. The erosive-evidence capability of the pump can be enhanced by using it. If the areas exactly where the liquid flows are manufactured of the stainless steel, the pumps can be utilized under the far more arduous situation.
· The exclusive style of the discharge port can safeguard the pump from the in excess of-force to guarantee the best productive overall performance in the doing work range of the pump.
· The motors are all adopted Y2 series merchandise. The defense class is IP54 or IP55 (normal is IP44) and the insulation grade is F.
· The bearings are all used the imported items with brand name identify of NTN or NSK.
