2BE3 Vacuum Pump

Vacuum Pump
    Overview:
  • Compared with 2BE1 series, 2BE3 series are different in the following aspects: They have higher suction capacity and lower vacuum, thus they are suitable for operations requiring large suction capacity such as mine gas discharge and pressure swing adsorption for chemical plants. Cylindrical ball bearings are replaced by double-row tapered roller bearings, thus service lives of the bearings are prolonged and load carrying capacities are improved. The‘concave-convex connector’for locating the pump and distribution plate is replaced by‘two pins on one surface’. The stop pins ensure the radial clearance between the impeller and pump. Air inlets and vents are arranged on both top and side end of the pump cover. In case that the gas shall be filled or discharged from the top, the side air inlets and vents are sealed by blank caps, thus there are more assembly options. High voltage motor may be available for the 2BE3 series since their energy consumptions and powers are increased due to large volumes and large suction capacities. The transmission is usually carried out by reducers. Pumps 50/52 may use belt transmission while pump 60 and superior ones shall adopt reducers for transmission. 2BE3 series have additional eccentric clapboards for dividing the pumps into two chambers with impeller middle plates. Air inlets and vents on side flanges make one pump adequate for operations requiring two pressure points, such as paper making.
