Garden pumps are mandatory for houses and villas located in areas that are not connected to a central water supply and sewage system. In such cases, only pumps can supply water for domestic needs and remove wastewater.
However, even if it is connected to a water supply, the house and villa still need a pump. Especially if you grow fruits, vegetables and fruit trees in your garden and yard - it is unthinkable to water them with water directly from the tap.
So the conclusion is definitely necessary - whoever has a house or a villa must have a garden water pump. The need for this machine and the variety of natural features and conditions of the terrains and yards have led to many varieties in the types of garden pumps. This makes the right choice a responsible task with a long-term effect, so we will make a brief overview of the types of pumps and their application, as well as typical solutions for providing your own, independent of the water supply network, water for irrigation, for production, sanitary and household needs, etc.
To enjoy trouble-free water use, you need to have the right type and characteristics of pump.
TYPES OF GARDEN WATER PUMPS
According to the tasks assigned to them, pumps can be distinguished into clean water pumps (domestic), drainage pumps and dirty water pumps.
According to the location where they are installed, water pumps are divided into surface and submersible.
Surface pumps are installed outside the water source, which also determines their operating principle – by suction from wells and reservoirs, for example. They are mainly divided into two types – vortex and centrifugal. Modern surface pumps are highly automated, which is of decisive importance not only for achieving optimal operating parameters of the machine, but also for their high energy efficiency. The maximum suction depth of this type of pump is 8–9 m (measured between the water level and the pump axis) at an altitude of about 1000 m. Near sea level it reaches up to 10 m.
Centrifugal garden pumps are used to pump water not only from wells and reservoirs, but also from other sources. Caring and thrifty homeowners collect rainwater flowing from roofs in tanks or cans suitable for the purpose. From them, it is pumped out and used for irrigation. The operation of these pumps is based on the action of centrifugal force, which entrains the transported liquid. Thanks to it, centrifugal pumps are also applicable for pumping water with a high air content. Among their main applications is watering the garden. Most specialists define these pumps as optimal for water supply to the house or cottage. An important and necessary condition for their proper functioning is the purity of the water from abrasive and fibrous impurities. In the event of such particles getting into it, there is a high probability that the pump will be damaged.
Submersible pumps are installed directly in the water source and allow water to be drawn from much greater depths. Their main application is to transport water from deep and narrow boreholes. Therefore, in appearance, you could easily recognize them by their cylindrical shape with a small diameter. They are placed in the water and can be used in two ways - to be installed permanently or to be transported to different places according to the specific need. An advantage of this type of pump is the ability to work with water with a high sand content. Most submersible pumps are characterized by a high efficiency factor /EFD/ and energy efficiency.
TYPES OF SUBMERSIBLE WATER PUMPS
Submersible pumps are mainly of two types – for wells and boreholes. Those for wells are mostly manufactured with a suction opening located at the lower end of the housing. This allows the pump to operate for a certain period of time in a partially submerged mode, in which the cooling of the unit is at the expense of the pumped water.
Borehole pumps used in the domestic sector are used to pump water from a great depth of a sandy or limestone aquifer. They usually have a small housing diameter, which allows them to be installed in smaller boreholes. Some models are installed horizontally and are used to pump water from rivers or lakes. There are submersible borehole pumps with high power, compact dimensions and high performance. Thanks to these characteristics, they can supply water from a great depth - hundreds of meters. They are generally made of stainless steel or various composite materials. They usually have built-in protection against dry running, i.e. in the absence of water.
DRAINAGE WATER PUMPS
Drainage pumps are designed to transport contaminated water containing algae, sand, leaves and whatnot. This type of pump pumps water from ditches, construction excavations and other similar places where it usually collects in spring or during heavy rainfall. They are important helpers in watering the garden, washing the site or the car, for example. We also use drainage pumps to pump out the pool or flooded basement. The good thing about them is that they have a long service life, are not demanding and do not require special technical care. In addition, they are small in size, which makes them portable and applicable for various tasks. Most are equipped with float switches that turn the pump on/off depending on the water level. Household drainage pumps are also used when it is impossible to use gravity drainage of wastewater, since the place from which the dirty water should flow is lower than the level of the sewer.
HYDROPHORIC SYSTEMS
Widely used for water supply from a local source to single-family and cottage buildings, agricultural and other buildings, automated irrigation systems, etc. are the hydrophore systems, which provide a continuous flow with almost constant pressure in conditions of cyclic water use and, accordingly, a cyclic pump operation mode. The hydrophore system allows for automated switching on and off of the pump depending on water consumption. It smoothes out to a very large extent the otherwise inevitable impulses transmitted to the water jet when starting and stopping the pump.
When choosing a pump, especially for hydrophore systems, some other factors should be taken into account. For example, it is advisable to install a filter at the pump inlet to clean the water from sand and other larger impurities. This undoubtedly helps to increase its durability, improves the quality of the water supplied for household (sanitary) purposes, and protects the nozzles of sanitary and other appliances from clogging. At the same time, the filter exerts significant hydraulic resistance, which leads to a decrease in the pump flow rate by about 300 l/h. To reduce losses, the diameter of the suction hose should not be smaller than the diameter of the pump inlet. Otherwise, this will cause an additional pressure drop due to increased friction.
