Water pump


Bomba de agua

Pompe de l'eau

Water pumps are used where tap water has too little pressure or is not recommended for use.

Water is pumped from the available source (cisterns, water barrels, a pond, creek or the like) and transported with suitable pressure to the consuming device usually some type of sprinkler. In order to cater for all possible applications, water pumps should feature a good intake height, sufficient pump lift (pressure in bar) and flow rate. An intake height of 8 m, a pump lift of 35 m and a flow rate of 5000 l/h are considered good. Additional criteria are weight, noise and service life. For the above mentioned reasons, multi-stage centrifugal pumps are preferred over single-stage (jet) models. Water pumps can also be used for evacuation purposes.
