What are submersible pumps? Submersible pumps are pumps which are submerged in the rainwater which is then pumped back. Since submersible pumps move underneath the collected rainwater, submersible pumps can pump the rainwater to the correct height. On the other hand, the power and permissible pressure of a submersible pump must be taken into account, there are many different submersible pumps. Submersible pumps pump the collected rainwater from the storage back to the tapping points where the rainwater can be reused. Examples of these tapping points can be: toilet flushing, garden watering or your washing machine. Industrial construction In industrial applications, pressure submersible pumps with a large capacity are available. GEP also has controls that can control two or three pressure immersion pumps. This makes it possible to have very large pump capacities, from small offices to large halls, for each project GEP has a suitable rainwater pump. Rainwater for everyone!
