Pumping unit for raising water pressure for the home: installation

With the onset of spring, depending on the area, the water pressure in the water supply system of residential buildings is significantly reduced. This common problem always requires a solution. You can demand the necessary pressure from the communal service, but for many reasons it is almost always impossible. Often in such situations, a conventional pressure boosting plant is used. The purchase of these devices can be paid individually or by all residents of the apartment building. It is always possible to install pressure boosters on your own.

Pump functions

Special installations that increase pressure, serve to stabilize the work of plumbing. The list of pump functions includes water supply of irrigation facilities, pumping of liquids, circulation in a variety of technological processes. Also tasks are being carried out to increase pressure in fire fighting systems, engineering structures for cold and hot water supply.

In some cases, low head pressure does not allow the use of household appliances in a private house, office or apartment. In such a situation, the installation of pressure increase in the water supply system will be simply irreplaceable.

Available Models

The widest range of produced imported and domestic up-grading pumps can be classified according to a number of main features. Devices can have automatic or manual trigger mode. According to the type of construction, centrifugal and in-line pumps are distinguished. Such instruments differ in the horizontal or vertical direction of rotation of the axis in the working system.

Pumps of the brand Grundfos

In many countries, these pumps are in very high demand. The products of the famous Danish concert with a flow sensor and wet rotor are cast iron UPA 15-90, as well as UPA 15-90N with anti-corrosion coating. The settings always differed in compact dimensions. The power of such pumps is small, they almost do not create noise and are made only of high-quality materials. Installation of water pressure increase due to such characteristics occupies leading positions among existing manufacturers of similar equipment. On the case there is a special switch, which allows to transfer the pump from manual to automatic mode of operation.

WILO products

The manufacturer specializes in pumps for a variety of purposes and produces such installations with wet rotors and flow sensors such as PB400EA, PBH089EA, PB201EA and PB088EA in a cast iron housing. Several advantages of the units can be distinguished: high resistance to corrosion, noiseless operation, relatively low power consumption, low weight and compactness, thermal protection system, easy mounting with nuts for fastening.

Pressure Waste Pumping Unit Wester

Most often used in the design of water supply systems for cottages, houses, individual apartments, small offices. Installed anywhere on the pipeline. These pumps can operate in different modes. A special switch is installed on the terminal block.

After selecting a specific position, the water pressure increase setting will work in one of several modes. This can be a permanent action, which does not provide protection against dry running. The pump can be switched off, but the water will still flow through it to the consumer. The device can automatically turn off when there is no liquid and operate at a flow rate of more than 0.033 liters per second.

Recommendations for choosing a pump

When choosing a suitable unit, you should pay attention to the maximum flow, head and power, the operating temperature range in which the pressure boosting unit functions normally, and also the noise level. The price of pumps can depend on the brand, performance, materials and technologies used in the manufacture. You can buy high-quality and compact units at an affordable price at special trading floors where construction materials are sold, in online stores with a fairly wide range of similar devices, as well as in stores selling sanitaryware. On the sites you can get acquainted with the technical characteristics of such pumps, see attached photos, and compare prices for a particular model, and get advice from a qualified manager.

Possibilities of using pumping stations

Often, pumps are used to assemble the irrigation system. In the simplest mechanisms, where only the supply of water is needed, there is no need for additional devices. Automatic control of the pressure increase in such cases is not required.

In some buildings, water supply systems are installed from wells. Such pumping stations always maintain the necessary pressure, shutting down and turning on automatically.

A multi-pump pressurization unit can be used with insufficient water pressure in the main pipelines. In combination with such devices, intermediate storage tanks are often installed. Pumping stations are not recommended to be connected to main water pipes directly because there is a risk of idling mechanisms due to lack of guarantees of continuous water supply or exceeding permissible pressure values.

Basic components in water supply systems

The pressure increase for the house can consist of a pressure switch, a hydraulic accumulator, and control and connecting equipment. Pumping stations are functionally characterized by the possibility of constant support of the necessary pressure in water supply systems and automatic regulation of their own work, depending on the use of water in the building.

Hydroaccumulators are metal tanks with a special inner rubber membrane and air pumped in pre-pressure through a nipple located under a plastic cover.

Pressure relays are electromechanical devices that respond to internal pressure in water supply systems, and the opening or closing circuits, depending on the head. The settings of this device can be adjusted.

The principle of operation of pumping stations

When the pumping station starts working, the pressure boosting unit automatically activates and starts pumping water to consumers. After the crane is closed, the hydraulic accumulator is filled, expanding the membrane and increasing the pressure in the water supply system. After reaching the preset pressure level, the relay switches off the pump. When the valve opens, the accumulator supplies the consumer with water under pressure. The pressure in the system will then decrease, and the pump will not be activated until a certain point. The relay turns on the pump again as soon as the head drops to a certain level.

Causes of pressure loss

With the change of time of the year, not only changes in the temperature of the environment occur, but also pressure in the water supply networks. This phenomenon is caused by several reasons: first - illiterate miscalculation of water supply systems during design, determination of the required diameter of the water pipe, the required capacity of pumping stations, average daily and hourly water flow. For this, it is necessary to take into account the terrain, number and population growth for the year, the length of the networks and other factors.

Installation of the pumping station

For proper operation of each installation, it is especially important to select the correct diameter of the suction pipe. The most suitable for this are flexible, non-reinforced reinforced hoses, as well as plastic or rigid metal products. When installing the suction pipe, sharp expansions, constrictions and turns must be avoided.

It must be ensured a constant slope of the pipe from the installation to the source of water intake in order to avoid the formation of air congestion or the accumulation of bubbles. To facilitate the filling of the suction line and the pump before starting, and also to prevent leakage from the system when the mechanism is shut off, check valves with a special screen filter are usually installed on suction pipes. The instructions for dismantling the pressurization unit require a preliminary pumping of water from the system and the subsequent disconnection of all components.

Pressure pipeline

No such stringent requirements are imposed on pressure equipment. Naturally, the diameter of the pipes without need not better not to narrow, so as not to create an additional loss of productivity and pressure when supplying water to consumers.

Conclusion

Technique makes life much easier for a person. The operation of many devices in the farm is connected with the supply of water. Pumping unit pressure increase is the most optimal choice in the matter of ensuring the normal functioning of household appliances. These devices are widely used today in agriculture, when designing domestic water supply systems or in extinguishing fires. To select such equipment correctly, it is necessary to determine its intended purpose and the necessary technical characteristics.
