Submersible pump with Aquarius logo

Aquarius brand pumps are attractive due to their affordability, extensive trade offers, maintainability

Line of centrifugal equipment

A wide range allows you to choose a pump for a well and a well, based on the flow rate of the source, the family's need for water, feed height, immersion depth

Restrictions on the pumped medium

Pump systems Aquarius are designed for pumping clean water. When choosing a pump, it is necessary to pay attention to permissible values ​​of mineral inclusions in water.

Water supply with centrifugal Aquarius

Submersible pumps with the Aquarius logo work in schemes with a hydraulic accumulator and a pressure switch that regulates the starting and stopping of pumping equipment according to pressure readings in the water supply system

Features of the device of the deep pump

All borehole submersible models of Aquarius have a similar structure.

The main parts are:

  • multistage pumping sector;
  • electric motor, separated by a filter;
  • condenser box outside

The pumping unit hides under the case - a monolithic box with rotating paddle wheels and a drive.

It is the dimensions of the impeller that are responsible for one of the main characteristics of the unit - performance. The larger its diameter, the larger the portion of water supplied over a certain time period.

All parts are securely fastened with a screw cap. It is also a place for fixing the cable, one of the pump fastening elements inside the well.

Pump device Aquarius

According to the table, you can trace the ratio of the dimensions of the apparatus and two important technical indicators - performance and magnitude of nominal head

An engine using a combination of rotor-stator and bearings drives the machine. It is filled with oil. Capacitors and electrical cable are enclosed in a condensation box.

In order for the equipment not to fail under force majeure circumstances, for example, during rapid drainage, German-made automatic protection is provided.

Work control and management is carried out using a remote device. Knowledge of the device Aquarius pump will help with its repair.

The principle of operation of the submersible apparatus

To supply water to the top and move it to the required distance, it is necessary to create pressure. The centrifugal type of pumps produces the necessary head by rotating the wheel (or several wheels), which is fixed on the working rod (shaft) and connected to the engine.

When starting the wheel, kinetic energy is generated, which is transmitted to the blades, and from them to the liquid. As a result, water is scattered to the walls, then from the receiver it moves to the next (upper) chamber, and in its place under pressure comes another portion of water from the well.

Principle of operation of the pump Aquarius

Thanks to a simple but well thought out device, water flows smoothly, sparingly, first into the body of the apparatus, then through pipes into the storage tank

A suction nozzle is used for collecting the liquid, and a filter is provided to protect the internal parts of the device from clogging and rapid wear. The device is simple, but so effective that it makes no sense to look for a device with a different principle of operation.

All elements of the mechanism are placed in a rather compact oblong "sleeve", the design of which is ideal for lowering into a narrow wellbore.

Unlike vibration analogs, centrifugal ones work evenly and carefully, due to which they do not lift sand from the bottom and do not destroy the borehole walls.

Purpose and characteristics of models

To reach a large audience, the company "Promelektro" manufactures models of various modifications. For convenient orientation, some parameters of the units are enclosed in their names.

For example, take the BTsPE 0.5-100U 60/150 position and decode the digital data:

  • BTSE - household centrifugal submersible electric pump;
  • 0.5 (l / s) - performance;
  • 100 (m) - nominal head at nominal flow rate;
  • 60 (l / m) - maximum performance;
  • 150 (m) - the height of the water rise in the well with the greatest pressure.

In accordance with individual requirements, you can choose a device belonging to one of four groups: 0.32 l / s, 0.5 l / s, 1.2 l / s, 1.6 l / s.

Suppose you own a well or small well (with a diameter of 100 mm, 120 mm and above) with a limited flow rate. Most likely, water consumption does not exceed 2 m3 / h. Obviously, the choice should fall on the model BTSPE-0.32.

Pumps Aquarius 0.32

The table shows the technical characteristics of all models of the Aquarius pump with a capacity of 0.32: using data analysis, it is easy to choose the device for your own use

Models with a productivity of 0.32 are quite popular, as many people visit the dacha irregularly, and the number of permanently residing people rarely exceeds 3-4.

If you decide to purchase a machine with a minimum performance, please note that other indicators may differ (for example, pressure parameters). This series consists of 9 models.

In the next series - BTsPE 0.5 - a total of 8 models differing in the size of the head (from 16 m to 100 m). Pumps can work with both manual and automatic control. The devices are equipped with a protective function that prevents overheating.

If the diameter of your well is not less than 110 mm, and the flow rate is from 2 m³ / h, you can choose one of the models of this series. The device can be useful for other purposes, for example, if there is a need to pump out water from a pool, pond or natural reservoir.

Pumping equipment with a capacity of 0.5 l / s is ideal for watering lawns, beds, flower beds or garden plantings.

Pumps Aquarius 1.2

Pumps Aquarius BTsPE-1,2 reaches maximum efficiency with water supply of 1.2 l / s (4 m³ / h): the graph reflects the dependence of the volume of water on the pressure

The next series - with a capacity of 1.2 l / s - includes a line of 8 products differing in pressure (from 12 m to 80 m). The manufacturer warns that hot water (with a temperature above +35 ºС) cannot be pumped, as well as too polluted liquid.

The most productive are the models of BCP 1.6, which are represented by three modifications - with a pressure of 25 m, 32 m, 40 m. In their range, they are different and structurally - they have a different number of stages of the pump part, from 6 to 8.

Given the technical characteristics of the pump Aquarius, you can choose the unit for individual requirements.

Selection of models for specific characteristics

Consider all the steps of selecting a brand pump. These recommendations are of a general nature. You can find more detailed information in the technical passport and installation instructions.

Comparison of Aquarius models

After specifying the technical data of the well and comparing the characteristics of different pumps, you can choose the model that best suits your site.

Before buying it is important to consider all the characteristics necessary for the correct choice.


  • borehole diameter;
  • well flow rate;
  • water levels in the well (static and dynamic);
  • estimated water consumption;
  • distance from the source to the house;
  • pressure in the hydroaccumulator (damping tank).

It is very easy to determine the diameter of the well - it is specified in the data sheet issued by the company that drills and installs the equipment. Most likely, the diameter is typical, that is, it has dimensions of 100 mm, 133 mm, 152 mm. Pumps Aquarius is better to install in wells with a cross section of more than 100 mm.

The debit is also specified in the passport, thanks to this parameter it is easy to choose the pump for performance. It is important that the pump parameters do not exceed the figures specified in the documents.

Suppose that the flow rate of the source is 3 m³ / h. This is a rather low figure, which means that models from the BTSPE 1.2 series (or higher productivity) are not needed, it is enough to BTSPE 0.5.

During the operation of more powerful equipment, the volume of water in the source will not have time to recover, there will be a dehumidification and automatic shutdown of the device.

The water level must be known to correctly determine the depth of installation of the pump. Usually the distance to the water mirror and from the surface to the bottom is indicated in the passport, but you need to remember a couple of nuances.

The first concerns the installation features of a submersible pump — it is lowered below the surface by 4–5 m. The second is the inconsistency of the water level.

In the warm period, the level is usually reduced, and the difference with the initial indicator can be up to 4-5 m. It turns out that for installation it is necessary to know the minimum level.

Private house water supply organization chart

Even at the planning stage of the water supply system, it is necessary to draw up a diagram of the house with an indication of all possible points of water discharge - the data will be useful both for wiring installation and for selecting a pump

To calculate the total water flow, several factors need to be considered:

  • the number of permanent residents;
  • the number of points of use inside the house (bathroom, kitchen, shower);
  • the presence of parsing points outside the house (watering the garden, a tap in the summer kitchen, a tap in the bath), etc.

On average, if you do not take into account additional objects, per person has a daily consumption of 200 liters.

The distance between the water source and the house is necessary to calculate the additional load on the pump. Standard calculation: 10 m horizontally laid pipes equals 1 m vertically located (both are 0.1 atmospheres).

The pressure of the damper tank affects the shutdown threshold. Suppose if you have a 300 liter tank installed, then to turn it off you need a pressure of 3.5 atmospheres (35 meters in vertical meters).

Pump automation

The circuit with submersible pumps includes an automatic control unit that regulates the work cycles, protects against overheating and dry running.

Caisson wells with a submersible pump

Most often for arrangement of a well with a submersible pump is constructed a caisson.

Rules and procedure for connecting the pump

In order for the Aquarius pumping equipment to work properly, it is important to install and connect it properly using the appropriate accessories.

Purchase of components for installation in the well

In addition to purchasing a pump, to which an electrical cable and a suspension cable are attached, it may be necessary to purchase the following equipment:

  • Hydroaccumulator with a set of adapters. For a small family (2-3 people) is enough small accumulator volume of 100 liters: the larger the volume, the less will the device be switched off).
  • Cap. Purpose wellhead - to cover the mine from street debris and precipitation, serves as a place of fastening pipes.
  • Pipe from pump to tank. Required for external use, with a diameter of 32 mm or 40 mm.
  • Pipe to Submersible Pump Adapter. For the Aquarius pump and pipes with a diameter of 32 mm, a product of type 1 ’with an outer cut of 32 mm is suitable.
  • Steel cable with clips. If the product supplied in the kit, for some reason does not suit.
  • Submarine cable. Used for electrical cables.

Together with the hydroaccumulator and the pump get pressure switch and pressure gauge. The equipment of German and Italian production has proved excellent.

For example, if the volume of the tank is more than 300 liters (8 atm.), The model of MDR 5-8 Grundfos is suitable.

Installation of pressure switch

One of the mounting options for the pressure switch and pressure gauge is by means of couplings, at the nozzle coming out of the hydroaccumulator (storage tank)

Preparation and liner pressure pipeline

To problems with water delivery from the well the house was smaller, the pipeline must have certain qualities.


  • tightness;
  • strength;
  • minimum length;
  • lack of bends.

Twists and turns may cause air bags that interfere with the movement of water. The shorter the pipe, the less need for connecting elements: fittings, couplings, flanges. Do not recommend using a threaded connection. A possible version of the product - pipe PND-32.

Water supply at the base of the submersible pump

The layout of the pressure pipe during installation of a submersible centrifugal pump: the pipeline is laid below the level of soil freezing with additional insulation

Check valve assembly

A non-return valve is not included with the pump, but its presence in the water supply at home is necessary. The main purpose of the valve is to block the movement of water in the opposite direction.

This means that in the process of work check valve open and allows the fluid to move freely towards the points of analysis. However, when the pump is turned off, it blocks the water, preventing it from moving backwards.

The valve is installed directly at the outlet of the well pump. It is mounted in the pipe above the pump, in some cases - at a short distance from it (no more than 1 m).

When installing the valve, pay attention to the arrow indicating the direction of water movement. This is necessary so as not to embed the part in reverse.

Check valve assembly

The installation of the check valve in the well is made on the pressure pipe immediately after the submersible pump. When installing a surface pump, the valve is fixed at the end of the nozzle that is lowered into the water

Fastening equipment on the cable

A nylon cable for mounting the pump is included, but some users note that over time, the elastic material loses its elasticity and stretches.

To prevent deformation, you can use a stainless steel cable. It is passed through special openings in the upper part of the pump casing and firmly tied.

Together with the cable must be lowered into the well and electrical cable. To prevent mechanical damage and additional load on it, you should make a kind of bundle of safety cable, pipe and electrical cable.

The cord is fastened not to stretch, but looped, with small allowances. It is forbidden to lift the pump from the well by the electrical cable.

Cable assembly

Something like this should look like a pipe after the pump is lowered into the well. Electric cable is fixed with special brackets or adhesive tape

Connected communication neatly lowered into the casing at a pre-calculated depth. In no case should the pump touch the bottom.

Electrical connection and testing

Remember that the operation of the pump Aquarius is possible only if the voltage parameters are maintained - 220 V. With other indicators, the normal functioning of the equipment is not guaranteed. If the network specifications do not meet the manufacturer’s requirements, connect Voltage regulator.

Having immersed the pump in the well, make sure that its body is completely in the water. The power cord should not be taut like a string. Only after checking the conditions fulfilled, proceed to connect the Aquarius pump to the power source.

If the device began to pump water and turned off only when the automation was triggered, everything was done correctly.

For the smooth operation of the equipment, preventive disassembly is carried out. If, after inspection, deficiencies are noticed, they must be eliminated. For example, you can replace the bearings (with a tight course), change the oil, check the motor winding.

You may also find information about how replace old pump with new oneset out in our other article.

Possible malfunctions and methods of their elimination

Despite the prevention, there may be cases of failure, so consider the most frequent of them.

Pump cleaning

Preventive cleaning should be done every 1-2 years, but emergency unscheduled repairs are possible if the parts are worn out or the suction nozzle is filled with sand before its time.

If the pump does not turn on, perform the following actions:

  • check the presence of contacts in the outlet;
  • inspect the pump for sand blocking;
  • measure the voltage, with a lack of connect the stabilizer.

If productivity has suddenly decreased, we check if there is a leak in the pipeline. At the same time inspect and clean the filters. When reducing the voltage, we use the stabilizer.

Sooner or later, the pump will become clogged with sand, so we make cleaning: we remove the net and protective chute, we separate the pump part and the electric motor, check the shaft operation, wash all the elements. We assemble the device in reverse order.
