aquarium inlet pump with their own hands

At the word “water pump”, many people immediately recall a complicated technical device that supplies compressed air for the operation of a pneumatic hammer in road construction. That is why when it comes to self-manufacturing aquarium water pump, it causes some confusion. Meanwhile, making a small device with your own hands for forcing air into the aquarium water is quite capable of almost anyone. But how to do it? And in general, why is it needed? Let’s try to figure it out.

What is air supply to the aquarium for?

Being a device for creating pressure (compression), the unit delivers air directly into the aquarium environment. This process is very important for ornamental flora and especially fauna. Fish are known to breathe through the gills with oxygen dissolved in water. If there is little oxygen in aqua, the very existence of pets will be at risk.

In the wild, the same thing happens, only the enrichment of water bodies with air occurs naturally: when blown by the winds and as a result of fluctuations in the water mass.

In the domestic artificial reservoir, such air saturation is performed using aeration — forced, controlled supply of air flow into the aquarium water. Moreover, the smaller the air bubbles emerging from the water pump, the more dissolved air is formed in the water space.

One can say this: a water pump is an ordinary air pump.

The main types of professional aquarium water pumps

Manufacturers of different countries have developed a wide variety of aquarium air pumps that can satisfy any owner of ornamental fish. Structurally, these devices can be divided into 2 main types:

Piston professional water pumps are more powerful and are designed for aeration in large-capacity aquariums, over 200 liters, for example. At the same time they are the most noisy, since the movement of the piston is always accompanied by a rather loud sound.

Membrane Air pumps are almost noiseless, their work is based on the movement of a rubber membrane that pumps air into the outlet tube.

Water pumps are also distinguished by the type of power source: either from a household electrical network or from batteries. There are also external and internal devices, if we consider the method of installation.

The price range of these technical devices is also quite wide – from several hundred to 20 thousand rubles (for example, the Italian pump Sicce MULTI), depending on the design, equipment, power and other characteristics.

Such a device can be assembled, if you understand the basic principle: first you need to somehow accumulate air, and then gradually submit it to the aquarium. This is the fundamental difference between an improvised unit and commercial piston or diaphragm pumps operating from an electric motor.

But how can you accumulate air? The answer suggests itself: in a balloon, car chamber, soccer ball camera, etc. By the way, it is the inflatable ball that some homemade craftsmen use in such cases.

So, in order to quickly and without special difficulties to assemble an aquarium inlet pump, you need:

  • rubber chamber (like an air battery);
  • car (or bicycle) pedal or hand pump;
  • three-way faucet (tee);
  • plastic tube from a medical dropper with a clip.

Three tubes should be taken from the tee: the first to the hand pump, the second to the inflatable ball, and the third tube (a dropper hose with a clip) will be the output hose. The end of this hose must be firmly plugged, and in front of it a tube must be punctured with several small holes, from which air will flow. Of course, all connections must be reliable and tight.

To collect air using a tee, the pump-chamber line opens first. The ball chamber is very durable in itself, so you can pump it up to failure. Then this direction is blocked and the “camera-outlet tube” line is turned on. In order for the air to enter the aquarium gradually, the diameter of the outlet tube in one place is regulated by means of a clamp. Naturally, this clip should be outside the aquarium, closer to the tee. Experienced way selects the flow rate of the air flow.

In principle, a homemade water pump is ready. The disadvantage of such a device is that the battery chamber must be periodically pumped. As a rule, for normal aeration of an aquarium with a capacity of up to 100 liters, such pumping should be carried out 2 times a day. Therefore, a homemade water pump cannot be left unattended for long.

DIY Aquarium Sprayer

It has already been mentioned that a larger number of small air bubbles have the best effect on the degree of oxygen saturation of water. This is achieved with the help of the so-called sprayer, which can also be made independently. Special knowledge and skills are not needed here.

First way: use of a short rubber tube that is put on the outlet hose. It is enough to pierce a set of holes with a needle from all sides of the tube, firmly plug its free end – and the sprayer is ready. By the way, such holes can be punctured on the air hose itself, but it is better not to spoil it and use a rubber spray nozzle.

There is another option. For example, a natural stone looks very impressive in an aquarium, from which a lot of air bubbles come out. For this fit myotis porous or porous limestone. But in this case, there are two problems. First, it is necessary to take into account the influence of the stone on the state of the rigidity of the aquarium aquatic environment. And secondly, it is necessary to ensure reliable fastening of the edge of the output air hose to the stone. In principle, a special silicone will help to successfully solve this problem.

If the “can” is low and long (there are such forms of aquariums), then the air should be sprayed in several places. Otherwise, all the fish will be collected in one place aeration.

You need to take a longer piece of rubber tube (almost equal to the length of the aquarium), and pierce the tiny holes in groups in several places at the same distance from each other. This tube can be placed on the bottom along the back wall and slightly decorated. Columns of air bubbles will rise from these areas, uniformly mixing water with oxygen. Yes, and looks like aeration is very attractive.

With the normal maintenance of ornamental fish and aquatic plants, the water pump is indispensable. Some advanced home craftsmen assemble such devices using standard electric motors, grind out the flywheel and pump parts on lathes, and place homemade devices in soundproof boxes. Of course, such technical home-made deservedly are the pride of their owners.

However, in all other cases, it will be easier and more reliable to purchase an inexpensive commercial water pump that, if properly used, will last a long time, providing pets with life-giving oxygen.

Why do you need an air pump in an aquarium?

Before you start making a water pump device for an aquarium, you need to be well aware of why your fish need it. Its main function is to oxygenate water. In addition, the bubbles rise to the upper layers and seem to form some kind of elevator, causing the surrounding fluid layers to move upwards. Water is thus additionally stirred, and its temperature becomes more uniform. Bursting on the surface, the bubbles break off the film of bacteria and dust, thereby slightly improving overall aeration. Even from the decorative point of view, an aquarium with a running water pump looks better than without it. The bubble chain represents an entertaining and pacifying spectacle that always attracts the viewer.

How to build a homemade air pump for the aquarium?

  1. For work, we need a conventional car or bicycle pump.
  2. A tube from a medical dropper.
  3. Tee or three-way valve.
  4. Self-made clamp or device for clamping the dropper, you need to adjust the air pressure.
  5. As an accumulator of oxygen, we will have:
    • bike or car camera;
    • football, basketball or other ball.
    • We assemble the construction as shown in the figure. The outlet is sealed, and the surface of the hose at the end is often pierced with a needle. We pump up our “accumulator”, shut off the hose from the pump and adjust the air pressure.

    This air pump for the aquarium, assembled with your own hands, will need to be pumped up about twice a day. It should be noted that the ball chamber enclosed in a leather shell will withstand greater air pressure, and therefore this device will work longer without paging. Of course, it is inconvenient to use this device for years, and it will not be possible to leave it for several days without supervision, but as a temporary device this self-made water pump is quite suitable.

    Aeration is the process of saturation and enrichment of water with oxygen. Such a process is extremely necessary in aquariums, especially large ones. In order to create aeration, an air pump for the aquarium is necessary. It gives small bubbles, which, rising, top, saturate the water with oxygen. One of the necessary conditions for a water pump is that it should work as quietly as possible, if not silently. Since aquariums are often located in rooms where people sleep most of the time, it must work constantly, especially at night, when plants do not emit oxygen.

    How To Make An Air Pump For The Aquarium Do It Yourself

    air pump for the aquarium, self-made – the best solution for those who do not want to put up with noise. But first you need to know what it consists of.

    The eccentric gear mechanism, pump and motor are the main parts of the water pump. The engine must have a power of at least 50 W to ensure normal operation of the pump.

    So, how to make an air pump for an aquarium and what is needed for that? To construct a pump, it is necessary to glue the tongues of valves in the inner part of the body.

    Using a gasket and a nut, press and fasten the diaphragm to the body. Now take up the engine. On the side surfaces of the flywheel you need to attach the plate with 2 screws, having an axis. The transmission node is the axis.

    This flywheel is put on the engine shaft. The magnitude of the eccentric transmission affects the plate with two slots that allow you to move the axis.

    From duralumin need to turn on the lathe bushings, flywheel and pump parts. Using an anvil and a hammer, plate washers should be made of duralumin washers. From a sheet of rubber one millimeter thick, mount the diaphragm.

    To make the aquarium air pump as silent as possible, you will need a box at the acoustic interchanges. This will help to neutralize vibration and sound transmission from the parts of the water pump to the floor, bedside table or table. Twenty millimeters thick boards should be made from the lid and box. Then fasten them with screws, and put foam on the bottom. Thick porous fabric is quite suitable for acoustic isolation, floor cleaning cloths are a great alternative to this. The cover needs to be glued with a cloth in order for it to close tightly, and make legs out of foamed polyurethane. In order for the water pump to have ventilation, the hose and the supply hole must be closed, but not tight.

    How To Make An Air Pump For The Aquarium Do It Yourself

    You can construct a simpler air pump for an aquarium, for example, using a ball or a rubber chamber. A rubber bulb pumps air through PVC tubes or silicone, and air is supplied to the sprayer. Using such a water pump, air is injected 1-2 times a day.

    And now our silent water pump is ready, now you need to remember to take precautions, do not lower it into the water, be sure to disconnect from the network if you want to open it or clean the aquarium. A water pump is essential for the inhabitants of the aquarium, including the plants in it. Creating such a necessary thing with your own hands will give you a lot of pleasure.
