Choosing a waterpump

Because not all liquids to be pumped possess the same characteristics, KOHLER-SDMO waterpumps meet multiple applications according to:

Water quality:

• Clean water or raw sewage: The AQUALINE INTENS range offers 2 versions depending on the quality of the water to be pumped:
  • The CLEAR 1.7 version is a small waterpump suitable for pumping clean water,
  • Versions ST 2.36 C5 and ST 3.60 C5, recommended for clean water, such as fish farming activities, pool transfers, etc.
  • Versions TR 2.36 C5 and TR 3.60 C5, specially designed for lightly soiled water, in particular for pumping muddy trenches, excavations, mud flats, etc.

• Highly loaded and High Pressure water: AQUALINE SPECIALIST waterpumps are designed for 3 types of use:
  • HP 2.26 C5 effectively cleans floors, terraces, agricultural or construction machinery. It is also extremely valuable as a first response in the event of a fire.
  • Models XT 3.78 C5, TRASH 3 C5 and TRASH 4 C5 are designed for heavily loaded water, especially extreme and intensive uses and accept solid particles of 20 to 30 mm.

Output and pressure required according to pressure drops.

The lift varies according to the configuration of the facility or the application (exhaustion, sprinkling, irrigation, emptying, washing). It is calculated using:

• Suction lift: this is the height between the level of the pumped water and the pump shaft. For physical reasons, it cannot exceed 8 metres above sea level.
• Discharge head: this is the height between the pump shaft and the highest point of the network.
• Head loss: this is the resistance encountered by the water in the pipes. It is calculated according to the length, diameter and quality of the pipes, their shape and the number of accessories (we use 20% for general cases).
