Hydroponic plant

For example, pumps can be surface or submersible. In stores you can also find pumps for water supply, which are not used for hydroponics. Hydroaccumulator is also useless in hydroponic devices, so buying such equipment is a waste of money.

Submersible or surface pumps - which kind is better for hydroponics

With the lifting of water to a small height, a submersible pump copes well. But a large container should be used for it, as the device is completely immersed in the liquid. If it is not immersed completely, it begins to trap air and quickly fails. Therefore, a submersible pump for hydroponics is suitable if the installation itself is located outside or in a greenhouse. Indoors, the submersible pump is not used.

Disadvantages of a submersible pump

Not suitable for small containers of liquid, as it must be submerged completely in water.
The cable of the device is always in the water and can deteriorate, exposing the wires. There is a risk of short circuits and electric shock.
If the water is not very clean, the device will clog quickly. You have to clean it often.
Surface pump for hydroponics is more suitable. In particular, you don't have to submerge it in water.

Advantages of a surface pump

Does not need to be submerged in liquid, so a large tank is not required.
Doesn't break down due to liming or salinity.
Easy and quick to clean.
Has built-in protection against overheating.

What to look for when choosing a hydroponic pump

Pumps can have different powers, power consumption classes, suction height, capacity.

For a hydroponic unit, a pump with a capacity of 2 thousand cubic meters per hour with a lifting height of more than 20 meters is suitable. The higher the height of water rise in your installation - the lower will be the final capacity of the pump.

For micro-installations, car or aquarium pumps are often used. As for the second option, it is not the best choice. Costs an aquarium device is expensive, and for the same amount of money you can buy a full-fledged surface pump.

What else to look for when choosing a pump for a hydroponic installation
Plant nutrient solution is considered non-aggressive, but it can negatively affect some parts of the device. For example, galvanized components of the device very quickly become corroded, so it is better not to use a pump with galvanized parts.

Cleaning the pump in a hydroponic installation

The operation of any pump is affected by lime and salt deposits. It begins to heat up, then stops and fails. It is recommended to clean the pump of deposits once a month or at each hydroponic solution change. When cleaning, do not use vinegar. It is better to use a special cleaner for cleaning the pump in the hydroponic system, which is sold in the store.

So, what conclusions can be made?

A surface pump is suitable for hydroponics.
Before buying, calculate its power and compliance with the other elements of the system.
Do not buy a pump with galvanized parts.
Take care of the device systematically to avoid clogging of salts, its liming and breakage.
