Well construction is a mandatory presence of a powerful pump in it. There is no other way to raise the water from the depth. More often, modern craftsmen prefer to use domestically produced equipment. This is the Kid pump. A small unit is quite efficient.
Device and principle of operation
The baby pump works with a membrane that divides the working chamber into two parts. One of them is filled with water, supplies liquid to the outlet, the second contains air.
When the device is turned on, the electric current supplied to the winding of the unit provokes electromagnetic oscillations. They are transferred to the diaphragm via a float valve. As a result, there are pressure differences in the two compartments of the working chamber. It is for this reason that water is sucked into the chamber and exits from it into the outlet.
The number of vibrations of the membrane per second is about 100 times.
Advantages and disadvantages
The main positive sides of the Kid pump:
- acceptable price;
- simple, understandable device and installation;
- relatively low noise level;
- good performance (enough for watering a garden or for supplying water for a family of 2-3 people);
- wide range (you can choose a device with upper or lower water intakes plus with additional protection systems).
The disadvantages of vibration pumps Kid include:
- constant vibrations of the device in the casing, which leads to its destruction (you can solve the issue with a tight rubber ring on the pump sleeve);
- loosening of the sandy bottom of the well, which leads to the failure of the working elements of the unit (you need to install a coarse filter with its regular replacement);
- corrosion of bolts, which, unlike the device body, are not aluminum, but steel.
For dirty well water, it is better to buy the Toddler model with an upper fence.
Model range and technical characteristics
There are three modifications of Malysh pumps on the market:
- Standard (aka basic). Has a lower water intake.
- Model marked "K". Performs the same functions as the basic modification of the device. But it is additionally equipped with overheating protection.
- Pump Kid marked "P". Here, with the same technical characteristics as in previous models, the only difference is in the case material. It is made of polymer.
Pumps Malysh-M and Malysh-3 have an upper water intake.
The technical characteristics for all modifications of the Malysh unit are identical:
- Productivity - 430 l / h when lifting liquid from a depth of 40 m. The shallower the depth, the higher the pump performance. Sometimes this value reaches 1050 l / h, if the water is raised from 1 m.
- Head - 40 m.
- Engine power - 245 W.
- The maximum immersion depth is 5 m.
- The period of continuous work is 2 hours.
It is better to turn off models without thermal protection every 120 minutes for at least half an hour.
How to choose a pump
The Kid's device for a well must be selected according to the following criteria:
- Desired amount of water supplied to the house. Calculated from the average family needs per day for each plumbing point.
- Well flow rate. If it is lower than the pump capacity, the source will quickly empty and will not be able to fill properly.
- Aggression. Here you need to calculate the length of the pipeline from the outlet to the farthest water supply point in the house.
- Casing diameter. It must be at least 100 mm.
- Source depth.
It is desirable that the Malysh pump flask is at least 10 mm less than the casing section.
Can I use the Kid's pump for a well
It is possible to use a vibrating unit of domestic production in a well if all the recommendations of specialists are strictly followed:
- it is advisable to install a mechanical filter on the inlet hose and change it regularly (at least once every 2 months);
- the diameter of the water supply hoses must be at least 18 mm;
- it is better to fix the pump in the casing on a nylon safety cable (steel will rust over time and break off);
- it is important to regularly lift the device and inspect it for malfunctions, sand contamination;
- during installation, it is better to immediately replace all the nuts for the bolts with self-locking ones in order to avoid their arbitrary untwisting in the water.
It is also important to put on a rubberized cuff before installing the pump. It will prevent the device from hitting the pipe wall.
The price of a submersible pump for the Kid's well varies somewhat depending on the length of its cable (in meters) and additional features: the presence of thermal protection, the type of water intake, the material of the body. On average, for a device in the markets of Moscow, you can pay from 1 600 to 2 250 rubles.
