Top 5 Centrifugal Pumps

The Italian company Altstream has long gained popularity among Russian consumers. It is valued for the high quality of its products and attractive prices. Before us is a centrifugal pump from this manufacturer and its main competitive advantage is low energy consumption. Only 550 watts per hour at maximum load. Not the lowest figure, if you do not take into account other technical aspects.

The depth of the well from which the pump is able to lift liquid is more than 9 meters, and the flow transfer is provided by more than 40 meters. For one hour of continuous operation, the device pumps almost 2.5 cubic meters of water, the temperature of which can reach 60 degrees inclusive. It works from a regular household network, but provides for a stationary installation. There is no cord with a plug that allows you to connect to an outlet. There are also no numerous sensors that are often present on the equipment of this brand. However, the model is from the budget price category and it makes no sense to demand more from it.

As a rule, a centrifugal pump provides for a stationary installation. The well may be located at a distance from the station, but its depth is strictly regulated in the parameters. This model is portable and this is its main advantage. The case even has a special handle for transportation, and the weight of the structure is only 8.5 kilograms.

The pump cannot be called weak. Its suction depth is 8 meters, which is the best indicator of this category. The maximum head is 48 meters, and the pumping speed is 3.8 cubic meters.In most cases, such pumps are equipped with powerful engines that have large overall dimensions. Here, the motor is small and light in weight, but at the same time requiring 1200 watts of energy. In fact, the device is also suitable for providing water to the house, since both the flow power and the pumping length allow this, but the portable design implies that it is more practical to use it for watering the garden using a well.

The Italian brand Pedrollo can be safely called the best manufacturer of sanitary equipment, including submersible and centrifugal pumps. They are often given top places in various ratings and this is due to the highest quality of their products. Only the warranty period for the purchased equipment is at least five years, and as reviews show, over the years you will generally forget about the existence of a pump in your home.

Of course, the manufacturer pays a lot of attention to quality, but you have to pay a lot. Before us is one of the most inexpensive models. Often, the cost of Pedrollo pumps reaches one hundred or more thousand rubles. At the same time, in technical terms, there is nothing extraordinary here, except for the throughput. 4.8 cubic meters. The best indicator, which in practice is unlikely to ever come in handy. The maximum suction depth is only 7 meters, that is, a long well or well for such a pump is no longer suitable. But the allowable liquid temperature is as much as 60 degrees, which is also a rare occurrence in practical use.

Flow capacity is one of the most important criteria when choosing a centrifugal pump. The parameter shows how many liters of liquid the device is able to pass through itself for a certain period of time. For this model, it was set at around 2.76 cubic meters per hour, and this is the best indicator, at least in this price category.

The pump can lift liquid from a well up to 9 meters deep, and the pressure provided reaches 30 meters. An excellent result, especially when taking into account the low energy costs. For operation, the device requires a household network of 220 volts and 370 watts per hour. This is one of the lowest consumption indicators, other things being equal. Of the shortcomings, one can single out the relatively large weight of the structure. More than five kilograms. However, in a stationary installation, which is most often used for centrifugal pumps, this is not at all a problem, although the noise level emitted by an all-metal electric motor should be taken into account.

The Russian brand Caliber is rightfully considered one of the market leaders in sanitary and specialized equipment. Its arsenal is dominated by pumps for domestic, private use. For example, this model is capable of transferring 1.68 cubic meters of water per hour and lifting it from a well up to 9 meters deep. The maximum pressure is 25 meters, and the power consumption is only 380 watts. The device works from a household network of 220 volts.

Also, the advantages include an all-metal construction, which significantly increases the service life. But it reduces the allowable temperature range.The pump works from plus 5 to plus 40 degrees, which is not so much compared to other models. But here is the most attractive price. According to users in the reviews, the device does an excellent job with the tasks, and all the characteristics that are present in the description exactly correspond to reality.
