 Performance range Eccentric screw pumps
| The data required for selecting an eccentric screw pump is of utmost importance.
The performance data shown as below must be used as a guide only and they are referred to product similair to cleaning water at 20°C.
In order to select the right pump model it is necessary to know the following data:
- capacity-flow rate: lt/min - mc/h.
- outlet pressure: bar or m.W.S
- suction pressure: positive/flooded suction - negative suction lift m.W.S
- viscosity: Cps - Cst of the medium
- specific gravity of the medium: kg/dm3
- percentage - max diameter of solid parts
- working temperature of the medium: C°
- kind of abrasion: ex:
- non abrasive liquids: water, emulsion water and oil, wine etc
- low abrasive liquids: dirty water, biological sludge etc
- abrasive liquids: slurry, lime milk
- high abrasive liquids: heavy slurries - emery sludge, dehydrated sludge - cement
with high sand concentration
- corrosion: PH, acid concentration, temperature.
- presence of solvents
Pump speed is in relation to the type of medium being pumped.
Relation above all refers to the abrasion and the viscosity of the medium.
Therefore, abrasive wear of eccentric screw pumps can be improved by decreasing pump rotational speed and by increasing the number of pump stages.
