Electric Water Pumps

Water pumps play an important role in flood table Irrigation in particular, but also in outdoor cultivation. Submersible pumps pump water from wells and ponds, while circulation pumps are used to supply a medium with nutrient solution.

Circulation pumps for the nutrient tank in indoor growing

Most circulation pumps are so-called centrifugal pumps. The name describes the essential operating principle of this type of pump as a centrifugal pump. Water or the already mixed nutrient solution is fed through a pipe connection and pressed outwards by a water wheel. The centrifugal force then causes the water/solution to be distributed. Thanks to their high efficiency, circulation pumps are also often used in heating technology.

Which pump do I need for my plants?

The selection of a suitable circulation pump for plant cultivation depends on several factors, not least of course the size or capacity of the nutrient tank. The following considerations usually play a role:

Delivery head: From what depth must the irrigation water or fertiliser solution be pumped? In the growing sector, this is usually well below one metre.
Flow rate: How much liquid do I need to supply my plants sufficiently? Many circulation pumps offer flow rates that are completely sufficient for almost all applications - often even oversized.
Power consumption: How much power does a pump consume in continuous operation. This factor is often negligible compared to lighting systems, for example.

Submersible pumps for plant irrigation

Conventional pump systems for table irrigation systems or small irrigation tanks for grow tents are unsuitable for larger tasks or larger cultivation areas in the greenhouse or garden because they are completely undersized. If you have a larger water / nutrient solution requirement, you will usually need a really large tank or even a well. And for this, of course, you need a submersible pump with plenty of power.

What do I need to look out for in a submersible pump?

To determine the right submersible pump for your needs, you should keep an eye on three specific factors and compare them with the conditions on site:

Delivery head of the submersible pump
Max. flow rate / hour
Performance / power consumption

The required delivery head is actually determined exclusively by the size of the tank from which the solution or water is pumped or the depth at which the pump is installed (whereby it is assumed that the edge of the tank represents the maximum required delivery head.

The total amount of water required in an hour is usually the comparative value for the pump's delivery rate. In short: is the result sufficient to cover the water and nutrient requirements of my plants?

You should also keep an eye on the output, as powerful pumps in particular can quickly become real power guzzlers.

Tip: Throttle submersible pumps

It's a shame if the submersible pump delivers more than you actually need. If you want to adjust your irrigation according to the season, you don't need several pumps with different flow rates, but can simply use so-called pressure valves, which simply throttle the amount of water flowing through.

Other applications for submersible pumps

Submersible pumps are also very suitable for domestic wells, which more and more people have been buying recently - but submersible pumps can also be used by those who are not necessarily looking for an alimentary, but rather a decorative purpose. As pumps for garden ponds, garden waterfalls and streams, they are ideal.water is one of the most precious commodities on this planet - so it is all the more important to use it responsibly - submersible pumps are ideal for distributing and dosing water.
