Liquid Vacuum Pump For Building Material China
2BV water ring vacuum pump for air and water vapour pressure to breathe, 33mbar absolute pressure (97%), vacuum pump suction pressure when in 80mbar below the condition, long-term work connected with protecting tube cavitation erosion of pump injector, i.e., protecting atmosphere, inspiratory pressure can reach 10mbar, injector pump can be directly mounted in a compressor, the pressure, to 0.26 MPa (maximum absolute pressure). 2BVwater ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.
1.The close-coupled design is convenient to install and can save space.
2.The bearings are all used the imported products with brand name of NTN or NSK
3.The standard seals are all used the John Crane mechanical seals, eliminating leakage, easy maintenance
4.2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump.
5.Aluminum bronze impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel,the pumps can be used under the more rigorous condition.
6.The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the 2BV vacuum pump.
7.The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.(normal is B).
8.2BVwater ring vacuum pump can achieve all of the PTFE flexible seal, which can greatly extend the working life in more demanding conditions
9.Running smoothly, the noise can be as low as 62 db.
