Water the garden, pump water into the tank from a well, river, lake or even from a well – all this can be done with a submersible pump Malysh. What is nice, it costs quite a bit, though it has modest characteristics, but it will be enough to water the garden or provide water for a couple of taps.
Application area
Submersible pump Kid has a low price, suitable for pumping clean water. It is better for them not to pump heavily polluted water – it will quickly burn out. It is applied in the following cases:
- for watering the garden;
- for collecting water in storage tanks;
- for water supply at home, but with certain restrictions (more on this below).
A kid can pump water from a well, a natural source – a pond, river, lake. It is suitable for dispensing water from containers. It can also be used for wells, but with reservations. Since the type of pump is vibratory, it creates vibrations in the water column, raising the smallest particles (silt, clay, sand) from the bottom and sucking them up. If in the case of a well this does not threaten anything but opaque water, then when using the Malysh pump in the well, it can quickly silt up. At least that’s the popular opinion.
Manufacturers in the recommendations for use indicate the minimum diameter of a well or well – 90-100 cm, some models (Kid 3) can work in sources with a diameter of 70-75 cm. However, they are also used in very narrow wells. The important thing is that he gets there. But at the same time, it beats against the walls of the well, creating additional vibration, and threatening to split the casing or damage its own body. To reduce the beating, rubber rings are put on the body (pictured above). They solve the problem.
Manufacturers
The name “Baby” and “Brook” has long become a household name. So today they call small submersible vibration pumps. Initially, they were produced exclusively in Russia or in neighboring countries, but today there are plenty of Chinese “Kids” on the market. In general, in Russia there are several manufacturers of such pumps:
- In the city of Livny in the Oryol region and in the Bavleny of Vladimirskaya, it is the Malyshs that are released. Most come with an upper water intake, Kids M with a lower one.
- Babies are also produced in Klimovsk, Moscow Region.
- In Kursk and Kirov (the Lepse plant) they produce pumps of the same type, but under different names – Aquarius.
- In Bryansk (Topol enterprise) they produce Rodnichki. With the same name, submersible pumps are produced in Chelyabinsk, and also by the Zubr company.
- Brook units are produced in Mogilev (Belarus).
Different names and firms, some differences in characteristics, but all these are submersible vibration pumps of the Malysh type
The rest of the brands are Chinese. How to determine? Carefully consider the packaging and passport. If this is a Russian manufacturer, there must be an address, the name of the enterprise, a list of service departments, etc. If there is no such information, this product is from the DPRK.
TECH SPECS
As already mentioned, Malysh submersible pumps have low power – mostly about 250 W, that is, he cannot create high pressure. Their clones with other names can be found slightly more powerful.
What is also important is the lifting height – this is how far water can be pumped. In the technical specifications, it should be more than the one you need by about 20%.
Pay attention to the power supply for which this model is designed. Usually this is 200 V with possible small deviations of the order of 5%, but the reality is that there may be 240 V in the network, and at this voltage a pump with such characteristics will burn out. The way out is to install a stabilizer or look for a model with a higher operating voltage (a decrease from the worker does not have such a negative effect on work – the power decreases).
Another important indicator is performance. It is usually specified in liters per minute or per second. This value shows how much water the unit is able to pump under normal conditions. For this type of equipment, this figure is quite small – about 400 ml / s. Such a submersible pump Malysh can provide water to one point of water intake – one irrigation hose or faucet in the house. It is not capable of anything more without additional equipment.

Each type of pump is presented with a different length of the electric cord and the price changes from this (the longer the cord, the more expensive). You can also find varieties with dry run protection, but you can make it yourself (see below).
Installation in a well or well
The submersible pump Kid is suspended on a synthetic cable. A metal cable or wire is quickly destroyed by vibration. Their use is possible if a synthetic cable is tied below – at least 2 meters. There are eyelets in the upper part of the case for its fixing. The end of the cable is threaded through them and carefully fixed. The knot is located no lower than 10 cm from the pump housing – so that it is not sucked in. The cut edges are melted so that the cable does not unravel.
Connecting hoses and pipes
A supply hose is put on the outlet pipe of the pump. Its inner diameter should be slightly smaller (by a couple of millimeters) than the diameter of the pipe. Too narrow a hose creates an additional load, due to which the unit burns out faster.
It is allowed to install flexible rubber or polymer hoses, as well as plastic or metal pipes of suitable diameter. When using pipes, the pump is connected to them with a piece of flexible hose at least 2 meters long.
The hose is secured to the nozzle with a metal clamp. Usually a problem arises here: the hose jumps off from constant vibrations. To prevent this from happening, the outer surface of the pipe can be processed with a file, giving it additional roughness. You can also make a groove for the clamp, but do not get carried away too much. It is better to use a stainless steel collar with notches – it gives additional rigidity to the mount.
Preparation and descent
The installed hose, cable and electric cable are pulled together, installing constrictions. The first is placed at a distance of 25-30 cm from the body, all the rest in increments of 1-2 meters. Bandages can be made from adhesive tape, plastic ties, pieces of synthetic twine, etc. The use of metal wire or clamps is prohibited – when they vibrate, they fray the sheaths of the cord, hose, or the twine itself.
A crossbar is installed on the head of the well or well, for which the cable will be attached. The second option is a hook on the side wall.
The prepared pump is gently lowered to the required depth. Here, too, questions arise: at what depth to install the Malysh submersible pump. The answer is twofold. Firstly, from the water surface to the top of the hull, the distance should be no more than the immersion depth of this model. For the “Kid” of the Topol company, this is 3 meters, for the PATRIOT unit – 10 meters. Secondly, there must be at least a meter to the bottom of the well or well. This is so as not to disturb the water too much.
If the Malysh submersible pump is installed in a well, it should not touch the walls. When installed in a well, a rubber spring ring is put on the body.
Having lowered the pump to the required depth, the cable is fixed on the crossbar. Please note: all weight must be on the cable, not on the hose or cable. To do this, when fastening, the twine is pulled, and the cord and hose are slightly loosened.
Installation in a shallow well
At a small depth of the well, when the length of the cable is less than 5 meters, to neutralize vibrations, the cable is suspended from the crossbar through a springy gasket. The best option is a piece of thick rubber that can withstand the load (weight and vibration). Springs are not recommended.
Installation in a river, pond, lake (horizontal)
The Malysh submersible pump can also be operated in a horizontal position. Its preparation is similar – put on a hose, fasten everything with ties. Only then the body should be wrapped with a rubber sheet 1-3 mm thick.
After the pump is lowered under water, it can be turned on and operated. It does not require any additional measures (filling and lubrication). It cools down with the help of pumped water, which is why switching on without water affects it extremely badly: the motor overheats and can burn out.
Features of operation
Some models of submersible vibration pumps for wells have overheating protection. This is a very useful feature that prevents the motor from burning out. During prolonged operation or in case of violations of operating conditions, the built-in thermal relay (protection against overheating) opens the power circuit, turning off the pump. After a while, the relay returns to its original state and work resumes.
If your pump has turned off due to overheating, it is advisable to immediately find out the cause. Shutdown can be caused by lack of water, increased voltage. If so, start the equipment only when everything returns to normal. Another possible reason is a clogged suction pipe. This can only be dealt with by taking out the pump, disassembling and cleaning it, which is contraindicated during the warranty period. Although, if your pump is clogged, you have already violated the rules of operation – it is suitable for pumping only clean water.
Dry run protection
Since many Malysh models cannot be lowered below three meters from the water surface, with a low flow rate, there is a threat that the water will run out, and the pump will continue to work and, as a result, will burn out. To avoid this situation, you can install a water level sensor. This is a float sensor, which is also called a “frog”. It works very simply:
- when it is raised up, the contacts are closed, power is supplied;
- when the water level drops, the float also drops, the contacts in the sensor open, breaking the power circuit;
- water is gradually drawn in, the float rises higher, at a certain level the contacts close again, the pump starts to work.
Such a sensor costs – less than 1 tr, it is installed simply – in the gap of the supply cable, but the benefits from it are great.
Working with a hydraulic accumulator
In general, vibration submersible pumps are not designed to work in conjunction with a hydraulic accumulator. They cannot create high enough pressure. But … under certain conditions they work. The assembly scheme is standard: a pump, a pressure switch, a pressure gauge, a hydraulic accumulator, all this is assembled through a five-pin fitting. For normal operation, a check valve is installed at the end of the submerged hose (so that water does not flow back into the well). Another condition is that the accumulator must be of significant capacity (100 or 150 liters).
Having assembled this circuit, you need to configure the pressure switch. It is asked the less, the better, otherwise the Kid will not have enough power. But even with a little pressure, everything will work on the strength of a couple of years, but rather – a year and a half.
What to do to work longer
Pumps like the Kid cost very little, but they also do not last long – about 2-3 years. In their production, inexpensive materials are used – to reduce costs. If, immediately after the purchase, some activities are carried out, as well as regular “technical inspections”, you can significantly extend the service life. So what can be done:
- The screws fastening the body should immediately be replaced with longer ones, supplemented with locknuts. If this is not done, the bolts become loose and break the stem.
- Once a month, inspect the pump; when pumping contaminated water, disassemble and rinse.
- When operating with a hydraulic accumulator, set the minimum pressure.
- Install dry run protection.
- Apply voltage through the stabilizer.
Some of the activities are costly. For example, a stabilizer costs about the same or even more than this pump, but it can be used with other types, and all of them will work better with a stable voltage. But changing the bolts is the key point that needs to be done.
