Recently, a fountain pump is used not only for decorating elegant bowls with water, but also for artificial ponds, which are increasingly found in household plots and summer cottages. These devices create spectacular streams of water or cascades of splashes that become a real decoration of the garden. The fountain pump essentially represents a special installation (pump) that absorbs water from a reservoir and throws various types of jets onto its surface.
There are several varieties of such devices. Most often, on household plots (even with cascades or waterfalls), a submersible fountain pump is used. Surface devices are used in the case when it is necessary to arrange several fountains at once or to create a waterfall with a large difference in height. Submersible fountain pump is installed in a selected place on a special stand. As it can be used bricks, flat stones. The casing of the device must be under water, but not touch the bottom. Water in this unit comes through a special filter, and then is thrown out through the nozzle. At the same time, in some pumps, the jet can be ejected directly above the filter or near it (using an outlet hose). Sometimes a “tee” is connected to this device, which allows delivering water to a cascade (waterfall) and blocking its flow to the fountain. Special bends allow you to install additional filters for water treatment.
Most often (in the conditions of Russia), at the end of the summer season, the fountain pump is removed from the reservoir, cleaned and left indoors until next spring. Low-voltage pumps, whose operating voltage is not more than 24 V, are suitable for small fountains. Their height rarely exceeds 1.2 m. They are also suitable for low cascades and waterfalls (up to 1 m). Submersible fountain
pumps for the pond are easily placed in the water column.
Surface units are placed in special boxes, which are installed near the reservoir. In this connection pipes must be made as short as possible. Surface fountain pumps are most suitable for large fountains and waterfalls. Finding the unit in the box allows you to quickly inspect and easily clean it for the winter. For continuous operation of the fountain, models with an asynchronous electric motor are used.
All pumps of this kind are divided into centrifugal, vortex, electromagnetic. Centrifugal units have a pressure and suction pipe. Before work, they are filled with water, which remains in them even after turning off. Vortex pumps have pressure and suction nozzles located above their axis. Filling such a unit with water is automatic. The operation of electromagnetic fountain pumps is based on the fluctuations of
electromagnetic pulses acting on a special fin valve.
The performance of these units depends on the power of the electric motor, the size of the pipes, the presence of bends in them. Fountain pumps for summer cottages and estates are selected taking into account the height of the water tank. It is also necessary to take into account the nozzle model, the height of the stream, the width of the waterfall threshold, and the size of the surface of the pond. Among the most popular fountain pumps are the devices AL-KO, SPRUT, MARINA, MESSNER SYSTEM, SICCE ECO POND, VERTO, STURM, GARDENA, GRINDA, AQVATICA.
