3 .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 pump.
4. The motors are all adopted YE2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.
5. The bearings are all used the imported products with brand name of NTN or NSK.
6. 2BV series water ring vacuum pump can achieve flexible sealing parts all of PTFE, which can greatly extend the life of the vacuum pump in harsh conditions
