Type of impeller: Radial-flow impeller L or Axial-flow rotor R
Radial-flow impeller = L Usage: Major pressure need to be overcome. (differential head, pressure drops, high specific weight or high viscosity) | Axial-flow rotor = R Usage: Free run out and no significant pressure losses.(decanting a huge amount of liquid) |

High delivery head
| High delivery rate
|
- heavy liquids (density > 1,0 kg/dm3)
- viscous liquids
- long discharge pipework
- differential head to overcome
- pressure drops due to valves, fittings,
flow meter - filling small canisters
- low power consumption at a small
flow rate (0 to 55 l/min) - small decrease of the flow rate at increasing operating pressure
- insensitive to changes in operating conditions
| - light liquids (density < 1,0 kg/dm3)
- thin-bodied liquids
- short discharge pipework
- low differential head to overcome
- low pressure drops
- emptying big containers, pumping high flow rates
- low power consumption at a larger flow rate (55 o 200 l/min)
- noticeable decrease of the flow rate at increasing operating pressure
- sensitive to changes in operating conditions
