The technical problems of the waste water transport by centrifugal pumps can be attributed predominantly to the pollution of the water and to the therefore necessary special pump geometry. Experience has shown, that pumps which are equipped with a single-blade impeller, show the smallest risk of ...

It will be noted that no pump or other accessories are necessary. It is important, however, not to allow the cup III to be entirely emptied during this process. If it is, then the entire system will promptly fill with air, thus requiring a purging operation before the unit can again be...
For these examples the described technical problems in the field ofpump technology are eliminated in the majority of cases. Thus the sewage transport, which isautomated to a large extent is very reliable.FRIEDRICH-KARL BENRAConference on Sustainable Development of Energy, Water and Environment ...
Complete pump characteristics (CPCs) are the key for establishing pump boundary conditions and simulating hydraulic transients. However, they are not normally available from manufacturers, making pump station design difficult to carry out. To solve this
The most crucial part of every ventilation system is the air pump, which consists of a housing and a motor with an impeller that can have different geometries. Market-leading manufacturers are working to enhance efficiency standards for the purposes of environmental protection and energy savings. ...
line-start permanent magnet synchronous motor has no problems with starting the pumping unit, even with a reduced supply voltage. The conclusions of this paper support a wider use of energy-efficient electric motors and can be used when selecting an electric motor to drive a centrifugal pump. ...
