Surface pumps are used to provide water intake within the garden plot. There is a whole line of household units of this type, which are a simplified version of a pumping station that requires a small amount of energy to operate. The Vortex PN-370 model is one of the most balanced solutions for such tasks, offering a wide range of functional equipment.
Pump assignment
The unit is designed to serve water flows with an intake from reservoirs for the purpose of local irrigation of a vegetable garden or garden. An important feature of the model, like all representatives of the group of garden surface pumps, is sensitivity to the working environment. That is, the sampling is carried out from uncontaminated sources with minimal inclusions of fibrous and abrasive elements with chemically aggressive compounds. AlsoThis version of the garden pump cannot be used outdoors if the temperature is below 1°C.
Arrangement and design
The pump is based on an integrated ejector that allows you to suck water from tanks at a depth of up to 9 m. That is, along with reservoirs, shallow wells with wells can also be used as sources. The configuration of the pipes is made according to the Venturi system, which creates favorable conditions at the stage of water intake and allows achieving high discharge pressures. The power base is formed by an electric motor, which is attached to the adapter flange of the Vortex PN-370 housing. The description of the connection between the pumping part and the engine can be expressed through the system of interaction between the impeller and the flow block. Thus, a classic self-priming pump system with a power base optimized for medium loads is realized. As for the materials of manufacture, they are heterogeneous. The body is made of cast iron, the adapter flange is made of aluminum, and some of the intermediate components and consumables are made of high-strength plastic alloys.
Operation principle
The pumping process is provided according to the vortex scheme with the help of the impeller. The rotation of the blades of the latter creates a characteristic movement of water in the gap between the wheel and the inner surfaces of the body. Unlike centrifugal units, the principle of operation and the device of a vortex pump is focused on the supply of the serviced liquid tocasing. Further, tangentially, the water is directed to the rotating wheel, where the effect of the suction force of the grooves between the blades is activated. The working process occurs cyclically until the moment when the forces of inertial suction and vortex attack are equalized. Despite the complexity of the flow pattern of the pumped liquid, the internal design of the unit is quite simple.

Operating instructions
The commissioning workflow of a pump consists of several steps, consisting of preparatory, communication and installation operations.
First of all, "Whirlwind PN-370" must be checked for technical and structural flaws, defects and other defects. It is recommended to place the case on a level ground, for which the flat mounting platform of the case is also designedin the lower part. If necessary, the structure can be fixed with bolts through the technological holes provided in the device. By the way, the very location of the equipment must be protected from flooding and precipitation.
At the stage of communication activities, conditions for connecting equipment are organized. First you need to install a 220 V socket, insert fuses into the network and provide grounding. Next, they move on to the directly pumping infrastructure. In this part, pipes from the suction circuit are mounted, which must correspond to the inlet at the end of the pump. Moreover, it must be borne in mind that with a suction height of 4 m or a line length along a horizontal plane of 20 m, the pipe diameter may exceed the size of the inlet pipe. It is also necessary to maintain the angle of inclination of the contour at least 1 degree with a decrease towards the water intake point.
Installation of a surface pump for a well is carried out in the following sequence:
- The suction pipe, together with the check valve, is connected to the inlet. Again, formats must be respected.
- The pressure line circuit is connected to the outlet at the top.
- The suction line and the pump are filled with water. To do this, remove the plug from the filler hole, perform the operation and reinstall the locking element.
- Checking the status of the power supply. At a minimum, use electrical measuring instruments to verify that the voltage reading is 220 V.
- The pump is connected to the mains.
Already during operation, the risks of water freezing should be taken into account. If the temperature drops below zero, then it is advisable to drain the water. This will avoid rupture of the pipeline and the very need to defrost the plumbing system. In addition, the design does not provide protection against "dry" running, so the user will have to control the filling level of the circuits and the pump themselves.
Maintenance instructions
During operation, the pump does not require special maintenance, but periodically at monthly intervals, the design should be checked for the same defects, damage and the presence of formed wear areas. At the end of the working season, the Whirlwind PN-370 pump should be disconnected from the communications and left to be kept in a dry room. Before that, it must be washed, dried and cleaned, if necessary. The unit does not require special preservation with the use of lubricants, but it is very important to create the correct storage conditions. The surface of the pump must not be exposed to direct sunlight or exposed to heating devices. After storage and before putting the equipment into a new operating cycle, its operating condition should be checked - for example, within the framework of a trial period, evaluate the energy consumption and pressure. If the pressure has noticeably decreased, this indicates signs of wear of the element base, and an increase in energy consumptionindicates strong mechanical friction within the structure.
Advantages of the model "Vortex PN-370"
In its segment, the model demonstrates good performance, as well as an acceptable level of reliability and ergonomics. Users point to the high quality of the assembly, the strength of the case and the well-thought-out configuration of the pipe system, thanks to which, in many respects, a balance is achieved between modest size and relatively high performance. For example, by the standards of an average surface pump for a household class well, a lift level of 30 m is a worthy indicator. And if this is not enough, then we can cite as an example the practice of connecting hydraulic seals, due to which new opportunities will be added to increase the suction depth. At the same time, the owners of the unit attribute high-quality sound insulation, a simplified installation scheme and undemanding maintenance to the positive aspects of operation.
Flaws of the model
Among the critical reviews about the pump, complaints about vibrations and overheating of the structure are more common. To a large extent, the manifestations of both shortcomings are determined by the operating conditions of the equipment. As already mentioned, the Whirlwind PN-370 model is sensitive to water quality, so excessive pollution may well lead to overload and automatic engine shutdown after 5-10 minutes of operation. As for vibrations, in addition to the same pollution, vibrations are often caused by violations in the installation and fasteningdesigns.
Conclusion
The model is a worthy choice as a budget-class garden transfer pump. Subject to the rules of operation, the unit will last for several years without requiring major repairs. In addition, the price of a water pump is about 2-2.5 thousand rubles. draws more attention to it. This is a more than justified amount, given the absence of flaws characteristic of lower-level equipment. On the other hand, when choosing, it is necessary to make a deep calculation of the required performance indicators, since the power filling may not be able to cope with high loads. We are talking about cases where it is planned to create high-performance lines with a deep well intake for subsequent distribution of flows over several irrigation zones.
