Autonomous water supply in the countryside - a prerequisite for a comfortable stay in the house. To supply fluid from a well or well, Stavr surface pumps are often used. They are mobile, compact and quite productive.
The principle of operation and arrangement of pumping stations Stavr
Units for water supply from the Stavr brand consist of the following work units:
- electric centrifugal pump;
- cumulative membrane tank (hydroaccumulator);
- pressure switch;
- pressure gauge;
- connecting fittings.
Additionally, the installation station is equipped with inlet and outlet hoses, as well as a coarse filter and check valve.
The principle of operation of the equipment:
- when turned on, the pump pumps water into the storage tank;
- as soon as the liquid, filling the reservoir to the limit, displaces air from the chamber, the pressure in it rises;
- the pump is switched off from this;
- here, when opening the tap in the house, water flows out of the accumulator through pipes, after which the pressure in the chamber drops;
- this is a signal to the pump for the next start, the pump again pumps up the supply of fluid.
The maximum permissible pressure in the tank chamber for Stavr stations is 2.4-3 atmospheres.
Lineup and Specifications
Two popular models of Stavr stations are presented on the market. Each of them is in demand depending on the tasks assigned to them.
Stavr NS-450/2
The equipment is designed to pump clean water from a well or well. The admissible size of impurities without fear for the operation of the pump blades is 5 mm. With larger specks, the unit will fail. The case of the NS-450/2 station is made of metal. The legs have special holes for reliable anti-vibration mount. Technical characteristics of the presented model:
- power - 450 W;
- head - 32 m;
- productivity - about 180 l / h;
- suction depth - 7-9 m;
- storage tank volume - 2 l;
- maximum temperature of the pumped medium - +40 degrees;
- the cross section of the inlet and outlet nozzles is 2.5 cm (1 inch).
The model is equipped with overheat protection. It has a factory cable with a length of 1.5 m. More often this installation is used in summer cottages. The device is not sufficiently productive as equipment for supplying water to a house with year-round living.
Stavr NS-600/20
The model copes well with maintaining normal pressure in the water supply system. With the help of such a station, it is possible to pump clean water with a possible value of impurities up to 5 mm. The unit is equipped with overheating protection.
Technical parameters of the station:
- storage tank volume - 20 l;
- power - 600 W;
- productivity - 300 l / h;
- depth of absorption - 8 m;
- head - 35 m;
- diameter of inlet and outlet nozzles - 3.2 cm (1 inch);
- permissible water temperature - +40 degrees.
For a more durable installation on the legs of the station body, special technical holes are provided.
Features of operation and maintenance
Stavr stations must be operated according to a number of specific rules:
- Installation of equipment is allowed only in a dry place. It is forbidden to operate the unit in the rain or in rooms with high humidity.
- Before starting up for the first time, always fill the system with water.
- It is necessary to ensure that the power cable of the station does not come into contact with other rough objects that could damage it.
- If it is necessary to extend the wire, make sure that the parameters of the added cable are designed for the power of the unit.
- Transfer station from place to place is possible only for the base.
- If there is any visible damage to the chassis, the operation of the equipment is prohibited.
The station is intended only for pumping clean water, in no case technical media or oils. After each seasonal use of the unit, it must be washed with clean water, lubricated and cleaned for the winter in a dry, warm place.
Owner reviews
Judging by the reviews of Stavr pumping stations, the equipment fully justifies the hopes placed on it.
Misha, 36 years old. I bought the station Stavr NS-600/20 to increase the pressure in the system in a private house, but with a central water supply. And then the shower was not to take. In the watering can not squeezed. Additionally, during installation, I adjusted the pressure to 3.5-4. And then the factory was not enough. It has been working for six months now. Everything is fine. It is in the insulated basement.
Zhenya, 29 years old. Station Stavr 450/2 took for cottages for irrigation. I noticed that if in the network, instead of 220, only 180 watts, the pump pumps weakly. I had to additionally drag the stabilizer out of the house. The unit is relatively quiet. In about 1.5-2 hours I completely fill 3 hundred parts of a garden and a kitchen garden. I take water from the well onto sand with a 3-meter water mirror.
