Many owners of summer cottages and private households that are not connected to a centralized water supply are familiar with the problem of supplying water to their homes and gardens.
The “Kid” submersible pump will help to partially solve it, which, although not a powerful device capable of pumping water from artesian wells, will quite cope with the supply of water from wells, shallow wells and open reservoirs.
It will be useful for those who are just going to equip an autonomous water supply, as well as users of pumping equipment, to learn about the device, the principle of operation and the rules for operating the unit. We will describe in detail how to install the "Baby" in the well and ensure its smooth operation.
Submersible pumps of the “Malysh” series are produced by the Russian enterprise Livgidromash, whose history goes back nearly seventy years. During this time, more than three million copies of various pumping equipment have rolled off the assembly line of the plant.
and "Kid-M" have a head of 40 m (maximum - 60 m), “Kid-3”- 20 m (maximum - 25 m). When working without pressure, productivity increases to 1500 liters.
The dimensions and power of the devices also have different indicators. So, the power of the basic model and modification with the letter “M” is 240 W, length - 25.5 cm, weight - 3.4 kg.
The power of the Malysh-3 pump is only 185 W, its length does not exceed 24 cm, and its weight is 2 kg, so it is usually used to draw water from shallow wells and wells with an internal diameter of 8 cm or more.
When buying a pump, you must first familiarize yourself with its technical characteristics and choose a model in accordance with the diameter and depth of the well (+)
Another parameter that you should know when buying a device is this. By default, all pumps that do not have this indicator have protection class 2.
The first class is indicated by the Roman numeral I. At the same time, class 2 devices are equipped with reinforced insulation, they are equipped with a cord with two cores. Class 1 devices are additionally equipped with a three-core cable with grounding.
The device and principle of operation of the pump
The device of the “Kid” pump is quite simple, it consists of a durable sealed housing that prevents liquid from entering, inside which there is an electric drive, including a core, two coils, an electric wire, and a vibrator.
In the upper (for pumps with an upper water intake) or lower (for devices with a lower water intake) part of the housing there is a valve that closes the inlets and provides free outflow or inflow of water in the absence of pressure.
Vibratory submersible electric pumps with an upper water intake last longer and break less, because they are less likely to become clogged with sand and clay suspension in the produced water
The operation of the pump is based on the use of alternating current, which, under the influence of a shock absorber, drives the armature and piston, causing them to perform mechanical oscillatory movements, while simultaneously pushing water into the discharge pipe.
Use and rules of operation of the device
Before operating the “Kid” pump, it is necessary to familiarize yourself with the rules for its safe operation. There are a number of restrictions under which the use of the device is strictly prohibited.
Safe Use Rules:
- the device must not be used with a damaged cord and with increased mains voltage;
- when the pump is on, it is forbidden to shut off the water supply;
- the unit should work no more than twelve hours a day;
- continuous operation should be no more than two hours with a periodic shutdown for twenty minutes.
All restrictions are described in detail in the instructions for the device, which must be read in order to avoid unforeseen consequences.

Vibratory submersible pumps are attached to two eyelets using a nylon cord (1). The hose is connected to the outlet with an elastic band (2)
The hose is connected to the outlet of the device with a clamp. If the vibration pump is supposed to be used in winter, then to prevent freezing and ensure free outflow of liquid, it is necessary to make a small hole of 1.5 mm in the hose next to the housing. In the summer, the hole can be closed with electrical tape.
Then, a nylon cord 10 m long, which is included in the delivery set, is fixed on the lugs of the pump. To increase the length, you can use a wire by attaching it to a nylon cord.
However, you can not attach a wire or metal cable directly to the submersible unit - this is fraught with breakage of the mounting holes.
It is necessary to calculate in advance the distance from the outlet to the water source. It depends on how long the cable is needed to connect the vibration pump. The kid is completed with a power cord 6-40 m long, its exact length is indicated in the instructions.
Thus, three cords should go from the pump: an electric wire, a rubber hose and a nylon cable. They must be connected to each other in several places with adhesive tape with an interval of 100-200 cm. Moreover, the first connection should be no further than 20 cm from the device body.
Flexible hoses are recommended for connecting the pump to the water supply. In the absence of acceptable use of polymer and steel pipes. In order to accurately mark the depth of immersion of the pump into the source, you can mark it on the hose with tape or colored tape
The specifics of installing the device in the well
During operation, the pump vibrates. It is possible that it will come into contact with the walls of the casing pipe or a narrow well, which will inevitably lead to damage to the casing and equipment failure.
To avoid this, before immersing the unit in water, it is necessary to put on a rubber ring on it, which will absorb possible shocks and serve as additional protection for the case.
The pump must be lowered into the water and set correctly, it must hang evenly, without touching the walls. A bar is installed on top of the well, to which a suspension made of durable elastic material is attached. Suspension is necessary to reduce vibration during operation of the device.
As a material, you can use a piece of rubber hose or a medical tourniquet. The upper end of the cable is connected to the suspension, creating a good tension. But for an electric wire, excessive tension is absolutely not necessary, it should lie freely on the bar.
The pump is suspended in water to a depth not exceeding three meters from the highest point of its body (+)
The new pump "Kid" is completely ready for operation, it does not need to be filled with water and lubricated before use. If the device you are using has protection class 1, . The device can be turned on immediately after immersion in a well or reservoir.
The distance from the bottom to the housing for devices with a lower water intake must be at least one meter. A submersible pump with an upper suction port can be lowered much lower, but in any case, its body must not touch the bottom to avoid damage during operation.
The diagram shows options for installing the pump in a casing pipe and in an open source of water. In the second case, you can do without a spring suspension (+)
In the event that water is pumped from shallow reservoirs, as well as when pumping flooded basements, the pump can be lowered to the bottom. The body must first be wrapped with a thick cloth or a sheet of rubber placed under the unit.

Pump Maintenance Malysh
In order for the pump to serve for a long time and properly, it is necessary to observe the operating and storage conditions recommended by the manufacturer. In this case, the manufacturer guarantees its normal operation for two years. The pump does not require complex maintenance and care, and it will not be difficult to follow simple rules.
After the first installation of the device in the well, you need to let it work for one to two hours, and then take it out and carefully inspect the body and components for faults. If everything is normal, then the vibration pump can be replaced and used further, leaving it immersed in water for a long time.
Periodically, at least once every three months, and if possible, then every hundred hours of operation, it is also necessary to inspect the unit. If at the same time traces of friction are found on the body, it means that it was installed incorrectly and, during operation, came into contact with the walls of the water intake.
To avoid this, it is necessary to set it evenly and put an additional rubber ring on the body.
If the inlet holes are clogged, they must be carefully cleaned without damaging the rubber valve. For cleaning, it is best to use a tool with a blunt end.
If the pump is not used in winter, it must be pulled out of the well, washed and dried well. During storage, the unit should be placed away from heaters and protected from direct sunlight.
