Pour un ménage typique, il existe deux principaux types de systèmes de pompes à eau de pluie parmi lesquels vous pouvez choisir.
D'autres systèmes de récipients sous pression sont disponibles, mais ils ne sont généralement utilisés que sur des maisons extrêmement grandes ou pour des applications commerciales.
De nombreux facteurs influenceront le type et la taille de pompe les plus appropriés pour fournir de l'eau dans votre maison.
Pour déterminer quel type de pompe convient le mieux à votre maison et à vos besoins, nous vous recommandons de parler à un revendeur de pompes professionnel.
Cependant, vous trouverez ci-dessous une introduction aux deux principales options de pompe pour la distribution de l'eau de pluie.
Pressure vessel pumps
Pressure vessel pumps create variable pressure systems. The usually work on 20-40psi/140-280kpa or 30-50psi/210-345kpa.
In systems with pressure vessel pumps, when a tap is turned on, water is drawn. Once the water pressure is down to 20psi/140kpa (the lower end of the two numbers), the pump starts up. When the pressure reaches 40psi/280kpa, the pump shuts off.
The volume of water that can be drawn before the pump starts will depend on the size of the pressure vessel. The bigger the pressure vessel, the greater the volume of water that can be drawn before the pump restarts.
Constant pressure pumps
Constant pressure pumps create constant pressure systems.
These pumps tend to use the same motor and pump body as variable pressure systems, however they also have a constant pressure control valve system fitted.
The latest pressure control valve systems are simple, efficient and very cost effective.
The final step in the Rain Harvesting process
Distributing the rainwater you’ve harvested and sorted is the final step in the Rain Harvesing process.
Because there are many water pumps available on the market, we don’t currently manufacture or sell pumps ourselves.
However, we do offer a range of filters which can be fitted prior to your pumps in order to deliver fit-for-purpose rainwater around your property.
