Autonomous water supply in a suburban area is 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 efficient enough.
The principle of operation and arrangement of pumping stations Stavr
- electric centrifugal pump;
- storage membrane tank (accumulator);
- pressure switch;
- pressure gauge;
- connecting fittings.
Additionally, during installation, the station is equipped with inlet and outlet hoses, as well as a coarse filter and a non-return 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 disconnected from this;
- here, when you open a 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 to turn on again, the pump again pumps up the fluid supply.
The maximum allowable pressure in the tank chamber for Stavr stations is 2.4-3 atmospheres.
Model range and technical characteristics
There are two popular models of Stavr stations 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 permissible size of impurities without fear for the operation of the pump blades is 5 mm. With larger specks, the unit will fail. The body of the NS-450/2 station is made of metal. The legs have special holes for a 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-over medium - +40 degrees;
- the cross-section of the inlet and outlet pipes is 2.5 cm (1 inch).
The model is equipped with overheating protection. Has a factory cable 1.5 m long. More often, such an installation is used in summer cottages for irrigation. As an equipment for supplying water to a house with a year-round residence, the device is not efficient enough.
Stavr NS-600/20
The model does a good job of maintaining normal pressure in the water supply system. With the help of such a station, you can pump clean water with a possible amount 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;
- suction depth - 8 m;
- head - 35 m;
- diameter of inlet and outlet pipes - 3.2 cm (1 inch);
- permissible water temperature - +40 degrees.
For a more stable installation, special technical holes are provided on the legs of the station body.
Features of operation and maintenance
Stavr stations must be operated adhering to a number of specific rules:
- Installation of equipment is only permitted in a dry place. Do not operate the unit in the rain or in rooms with high humidity.
- Always fill the system with water before using it for the first time.
- It is necessary to ensure that the power cable of the station does not come into contact with other rough objects that can damage it.
- If it is necessary to lengthen the wire, make sure that the parameters of the added cable are designed for the power of the unit.
- You can move the station from place to place only by the base.
- Do not operate the equipment if there is any visible damage to the case.
The station is intended only for pumping clean water, in no case technical fluids or oils. After each seasonal use of the unit, it must be rinsed with clean water, lubricated and cleaned for the winter in a dry, warm place.
Owner reviews
Judging by the reviews about the pumping stations Stavr, the equipment fully justifies the hopes placed on it.
Misha, 36 years old. I bought the Stavr NS-600/20 station to increase the pressure in the system in a private house, but with a central water supply. And even then it was not to take a shower. It didn't squeeze into the watering can. 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 already. It's okay. Stands in a heated basement.
Zhenya, 29 years old. I took the Stavr 450/2 station for watering. I noticed that if there is only 180 W in the network instead of 220, 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 in 3 acres of a garden and a vegetable garden. I take water from a well onto the sand with a water mirror of 3 meters.
