Overview of borehole pumps Aquarius

An autonomous water supply system requires injection equipment. With its help, the water supply is carried out in full. For narrow wells, it is better to use submersible pumps. The flask-shaped devices are ideally placed in the casing without damaging its walls. Thanks to the optimal technical characteristics of the Aquarius submersible pump, it is possible to raise water from any depth (wells on limestone or sand).

The device and principle of operation of pumps Aquarius

The downhole pumping equipment of the Kharkov plant "Promelektro" has a similar structure, regardless of the model. The main working elements of the unit:

• Electrical engine;
• coarse filter;
• capacitor box;
• centrifugal wheel with blades and drive.

The pump works according to the following principle:

• When connected to the network, the engine starts the operation of the blades of the centrifugal wheel.
• It, in turn, creates kinetic energy, which sucks in water through the inlet and scatters it along the walls of the flask.
• The liquid gradually rises into the upper receiving chamber and then enters the water pipes.
• A new portion comes under pressure to replace the left water from below.

Centrifugal blowers, unlike vibrating two-valve BV, work carefully, gently, without sharp fluctuations. They do not destroy the casing of the well, do not raise small grains of sand from its bottom.

Model range and technical characteristics

Aquarius pumps have a wide range of models. Modifications are designed for different well parameters. The main technical characteristics of each type of unit are contained in its name. This allows the user to navigate through the variety of models.

Example: pump BTsPE 0.5-100U 60/150. Decoding:

• BTsPE - household centrifugal submersible electric pump;
• 0.5 (l / sec) - equipment productivity;
• 100 - head in meters;
• 60 - maximum maximum productivity in liters / minute;
• 150 - height of liquid transportation at maximum head.

In total, Promelectro produces four groups of centrifugal apparatus, each of which also has its own line of 8-9 models:

• Submersible pumps Aquarius (NVP) with a capacity of 0.32. You can choose a pump for a well of different diameters.
• In the category BTsPE 0.5, there are 8 modifications of the units. All of them differ in terms of head indicators (from 16 to 100 m). In addition, they can be operated from manual or automatic control.
• The pumps from the category 1.2 l / s are a line of 8 models. They differ in pressure (from 12 to 80 m).
• The group of equipment with a performance of 1.6 is considered the most powerful. The pumps here differ in the head indicator (25, 32 and 40 m), as well as structurally (they have from 6 to 8 stages of the pumping part).

For an accurate selection of the required Aquarius model, it is advisable to calculate the well flow rate and the approximate water consumption per family per day.

Advantages and disadvantages

The main advantages of submersible units Aquarius:

• relative noiselessness, in contrast to vibration;
• economical consumption of electricity;
• compact dimensions;
• wear resistance of brass, stainless and polymer working elements;
• complete set, which allows you to immediately mount the equipment.

All Aquarius pumps have the international safety standard IEC 335-1 and are warranted for 1.5 years.

How to choose a pump Aquarius

When buying a submersible screw pump Aquarius, the choice must be based on the following criteria:

• the section of the casing (as a rule, it is from 4 inches or 100 mm);
• water mirror in the well;
• source debit;
• distance from the well to the water supply points (pipeline length);
• estimated fluid consumption per family;
• pressure in the damper compartment.

It is advisable to ensure that the technical characteristics of the equipment do not exceed the capabilities of the well. The operation of an overly productive apparatus will lead to the fact that the source will not have time to fill. As a result, it will drain and then turn off the pump.

Installation and connection

In order to fully install the pump and ensure its uninterrupted operation, you can complete the system with a 50-100 liter hydraulic accumulator and a head that will protect the source shaft from debris entering it.

The installation of the unit in the well is carried out in several stages:

1. It is necessary to install a non-return valve. It will prevent water from flowing back from the piping to the chambers of the device. The valve is mounted immediately at the outlet of the working chamber of the equipment into the pipe, just above the pump itself. Its installation is allowed at a distance of up to 1 m from the unit. It is important to pay attention to the arrow on the check valve. It always shows the direction of water flow. The element must be placed with an upward arrow. If you do it otherwise, the valve will work in the opposite direction, will not let the liquid into the receiving pipes.
2. The pump is fixed on a strong cable. It is advisable to use nylon rather than steel. The second option, under the influence of moisture, will eventually fail, corrode, and tear.
3. In parallel with the cable, an electric cable and a water supply pipe are launched, which is mounted to the outlet of the equipment. It is advisable to fasten all three elements along the length with clamps, adhesive tape with a pitch of 40-50 cm. This will prevent the rope or cable from sagging. Remember, it is forbidden to fix the safety rope and cable tightly. It is desirable to have them in a moderately free position.
4. Once all the elements of the unit are assembled, you can lower the Aquarius into the casing to the marked depth. It is forbidden to install the device on the bottom. The minimum distance from the lowest point of the well to the pump is 1 m.
5. It remains to connect the equipment to the network. Its operation requires a voltage of 220 V. If there is a problem with this indicator, it is better to install a stabilizer.

Continuous operation of the pump and its automatic shutdown indicate that the installation was performed correctly.

Operation and maintenance

Judging by user reviews, the Aquarius unit works without failures. However, it is necessary to carry out its preventive maintenance, which consists in regular activities:

• replacement of bearings with a tight stroke;
• checking the motor winding;
• oil change;
• checking the pump for sand blockages;
• replacement of the coarse filter;
• checking the tightness of the pipeline.
• flushing of the working shaft elements.

It is advisable to perform such actions at least once a year. More often if necessary.

The price of a submersible pump for the Aquarius well depends on its technical characteristics. On average, in the Moscow region for a centrifugal unit for a well, you can pay from 1,800 to 27,500 rubles.

Owner reviews

Nikolay, 35 years old. A year ago, I built a house on my site and finally drilled a hole in the sand. I tried to pump it with a vibration pump. I suffered for about two months. Of course, the sand became less, but it did not completely disappear. Then a neighbor suggested that it is better to install a submersible centrifugal unit. I bought Aquarius BTsPE 0.5-25 U. After its installation, by the evening the well began to give completely clean water. The device works quietly. The performance is good enough for my wife and me.

Yura, 41 years old. We have a well on the site for a long time. Although the house is supplied with central water supply. But literally in recent months, the water supply to the village was very poor. We decided to pump from the well using a vibration pump.For about a month of such operation, we pretty much chipped one of the concrete rings of the well. We came to the conclusion that it is necessary to install a centrifugal submersible unit. The choice fell on "Aquarius". Now we don't know the problems. The water mirror in the well is 5 m, and the distance to the house is only 18 m. There is enough pressure and productivity.
