Aquarius - an excellent choice for a country well
Convenient to use and install the unit produces the company "Promelectro" (Kharkov, Ukraine). In addition to submersible pumps, the company produces drainage and surface pumping equipment, electric motors, and feed choppers.
A series of pumps for in-depth use includes products operated in wells installed “on sand” and “on limestone”. The range of distance from water intake to its supply to the surface is from 20 to 200 m.
The most powerful models can serve a large cottage or 2-3 cottages, as their productivity reaches 12 m³ / h.
Among the advantages of the Aquarius line of devices are:
- economical energy consumption;
- high performance;
- low noise figure;
- wear resistance of parts made of stainless steel, brass and safe food plastic;
- the possibility of warranty or self-repair;
- light weight and dimensions corresponding to the diameter of the well;
- fully equipped, allowing you to immediately begin installation.
Do not forget about IEC 335-1 (international safety standard), warranty service for a year and a half and the possibility of need repair purchase spare parts from the manufacturer.
In terms of technical characteristics, the modifications are comparable with foreign analogues of PEDROLLO and GRUNDFOS. Cost depending on the model - from 1800 rubles. up to 27 400 rub.
Features of the device of the deep pump
All borehole submersible Aquarius models have a similar structure.
The main parts are:
- multistage pumping sector;
- motor separated by filter;
- condenser box located outside.
A pump unit is hidden under the body - a monolithic box with rotating impeller wheels and a drive.
It is the dimensions of the impeller that are responsible for one of the main characteristics of the unit - productivity. The larger its diameter, the larger the portion of water supplied over a certain time period.
All parts are securely fastened with a screwed cap. It is also the place of fixation of the cable, one of the fastening elements of the pump inside the well.
Using a combination of a rotor-stator and bearings, the motor drives the apparatus. It is filled with oil. Capacitors and electrical cable are enclosed in a condensation box.
To ensure that the equipment does not fail under force majeure circumstances, for example, during quick drainage, automatic protection of German production is provided.
Monitoring and control is carried out using a remote device. Knowledge of the Aquarius pump device will help with its repair.
The principle of operation of the submersible
To supply water up and move it to the required distance, it is necessary to create pressure. The centrifugal type of pumps produces the desired pressure by rotating the wheel (or several wheels), which is fixed to the working rod (shaft) and connected to the motor.
When the wheel starts, kinetic energy arises, transmitted to the blades, and from them to the liquid. As a result, water is scattered to the walls, then it moves from the receiver to the neighboring (upper) chamber, and another portion of water from the well comes into its place under pressure.
A suction pipe is intended for fluid intake, 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 elongated "sleeve", the design of which is ideal for descent into a narrow wellbore.
Unlike vibrational counterparts, centrifugal work evenly and gently, so they do not raise sand from the bottom and do not destroy the walls of the well.
Purpose and characteristics of models
To reach a large audience, the company "Promelectro" produces models of various modifications. For convenient orientation, some parameters of the units are contained in their name.
For example, take the position of BTsPE 0.5-100U 60/150 and decode the digital data:
- BCPE - household centrifugal submersible electric pump;
- 0.5 (l / s) - performance;
- 100 (m) - nominal pressure at nominal volumetric flow;
- 60 (l / m) - maximum performance;
- 150 (m) - the height of the water in the well at the highest pressure.
In accordance with individual requirements, you can choose a device that belongs 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 go beyond 2 m3 / h. Obviously, the choice should fall on the BTsPE-0.32 model.
Models with a productivity of 0.32 are quite popular, as many people visit the cottage irregularly, and the number of permanent residents rarely exceeds 3-4.
If you decide to purchase a device with minimal 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 pressure (from 16 m to 100 m). Pumps can work with both manual and automatic control. The devices are equipped with a protective function that protects against overheating.
If the diameter of your well is at least 110 mm, and the flow rate is from 2 m³ / h, you can choose one of the models in this series. The device can also be useful for other purposes, for example, if it becomes necessary to pump water from a pool, pond or natural reservoir.
Pumping equipment with a capacity of 0.5 l / s is perfect for watering lawns, beds, flower beds or garden plantings.
The next series - with a capacity of 1.2 l / s - includes a line of 8 products that differ 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 contaminated liquid.
The most efficient models are BTsEP 1.6, which are represented by three modifications - with a pressure of 25 m, 32 m, 40 m.
Given the technical characteristics of the Aquarius pump, you can choose the unit according to individual requirements.
Model selection for specific characteristics
Consider all the stages of choosing a brand pump. These recommendations are general in nature, you can find more detailed information in the technical passport and installation instructions.
Before buying, it is important to consider all the characteristics necessary for the right choice.
- well diameter;
- well flow rate;
- well water levels (static and dynamic);
- estimated water consumption;
- distance from the source to the house;
- pressure in the accumulator (damper tank).
The diameter of the well is very simple to determine - it is indicated in the data sheet, which is issued by the company that performs drilling and installation of equipment. Most likely, the diameter is typical, that is, it has dimensions of 100 mm, 133 mm, 152 mm. Aquarius pumps are best installed in wells with a cross section of more than 100 mm.
The flow rate is also indicated in the passport, thanks to this parameter it is easy to select the pump according to capacity. It is important that the pump parameters do not exceed the numbers indicated in the documents.
Suppose the flow rate of the source is 3 m³ / h. This is a rather low indicator, which means that models from the BTCPE 1.2 series (or higher performance) do not need to be purchased; BTCPE 0.5 is enough.
When more powerful equipment is in operation, the volume of water in the source will not have time to recover, and the device will be drained and automatically shut off.
The water level must be known in order to correctly determine the installation depth of the pump. Usually the distance to the water mirror and from the surface to the bottom is indicated in the passport, however, a couple of nuances must be remembered.
The first concerns the installation features of the submersible pump - it is lowered 4-5 m below the surface. The second is the instability of the water level.
In the warm period, the level usually decreases, 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.
To calculate the total water flow, several factors must be considered:
- 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 bathhouse), 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 of horizontally laid pipes equals 1 m of vertically arranged pipes (0.1 atmospheres for both).
Damper tank pressure affects the trip threshold. Suppose if you have a volumetric tank of 300 l installed, then to turn it off, you need a pressure of 3.5 atmospheres (translated into vertical meters - 35).
Rules and procedure for connecting the pump
In order for the pumping equipment of the Aquarius brand to work properly, it is important to correctly install and connect it using the appropriate accessories ..
Purchase of components for installation in a well
In addition to buying a pump, to which an electric cable and a cable for hanging are attached, it may be necessary to purchase the following equipment:
- Accumulator with a set of adapters. For a small family (2-3 people) is enough small accumulator 100 l: the larger the volume, the less often the device will turn off).
- Head. Destination well head - cover the mine from street debris and precipitation, serves as a place for 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 a Aquarius pump and a pipe with a diameter of 32 mm, a product of type 1 ’with an external cut of 32 mm is suitable.
- Steel wire rope with clamps. If the product supplied is not suitable for some reason.
- Submarine cable. It is applied to electric cables.
Together with a hydraulic accumulator and a pump, they acquire pressure switch and pressure gauge. The equipment of German and Italian production has proven itself perfectly.
For example, if the tank volume is more than 300 l (8 atm.), The MDR 5-8 Grundfos relay model is suitable.
Pressure line preparation and connection
To problems with water delivery from a well the house was smaller, the pipeline must have certain qualities.
- minimum length;
- lack of bends.
Turns and bends can cause the formation of air bags that interfere with the movement of water. The shorter the pipe, the less need for connecting elements: fittings, couplings, flanges. It is not recommended to use a threaded connection. A possible version of the product is the PND-32 pipe.
Check Valve Installation
The non-return valve does not come with the pump, but its presence in the home water supply device 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 parsing points. However, when the pump is turned off, it blocks the water, preventing it from moving backward.
The valve is installed directly at the outlet of the downhole pump. It is mounted in a pipe above the pump, in some cases - at a small 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 with the back side.
A nylon cable for mounting the pump is included, however, 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 threaded through special holes in the upper part of the pump casing and firmly tied.
Together with the cable, it is necessary to lower the electric cable into the well. To prevent mechanical damage and additional load on it, you should make a kind of bundle of safety cable, pipe and power cable.
We fasten the cord not in a stretch, but in a loop-like manner, with small allowances. It is forbidden to lift the pump from the well by the electric cable.
We carefully lower the interconnected communications into the casing to a predetermined depth. The pump must never touch the bottom.
Power Connection and Testing
Remember that the operation of the Aquarius pump is possible only if the voltage parameters are observed - 220 V.With other indicators, the normal functioning of the equipment is not guaranteed. If the network specifications do not meet the requirements of the manufacturer, connect Voltage regulator.
Having plunged the pump into the well, make sure that its casing is completely in the water. The power cord should not be stretched like a string. Only after checking the fulfilled conditions, 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 shortcomings are noticed, they must be eliminated. For example, you can replace the bearings (with a hard run), change the oil, check the motor winding.
You may also find useful information on how to replace old pump with newset forth in our other article.
Possible malfunctions and methods for their elimination
Despite prevention, there may be cases of breakdown, so consider the most common of them.
If the pump does not turn on, perform the following steps:
- check the presence of contacts in the outlet;
- inspect the pump for clogging with sand;
- measure the voltage, with a lack of connect the stabilizer.
If productivity suddenly drops, we check to see if a leak has appeared in the pipeline. At the same time we inspect and clean the filters. When reducing voltage, we use a stabilizer.
Sooner or later, the pump will become clogged with sand, so we clean it: remove the mesh and the protective groove, separate the pump part and the electric motor, check the shaft operation, and rinse all the elements. We assemble the device in the reverse order.
