Modern pumping equipment is developed with the expectation of increasing functionality and productivity. This approach allows you to meet the needs of consumers from different segments, while maintaining the optimal balance in technical parameters. However, universal products in this niche do not always justify themselves during operation, therefore, a considerable part of manufacturers nevertheless clearly classifies units for different purposes. This includes the Espa pump, which is available in several design variations.
Drainage models
The products of this line can be used to rid the soil layer of moisture, empty pits and basements from water, and also to perform other tasks of this kind. The basis of the category are models of the Vigila family. Representatives of this group differ in lifting height and productivity. In particular, the initial level is represented by a modification of 50-500, which is capable of pumping 15 m 3 / h at a depth of up to 4 m. The more productive Espa submersible pump in SS design allows the extraction of about 16 m 3 per hour. At the same time, the lifting height is 8 m. In the same class, centrifugal vortex units can be noted, the design of which provides for the high-strength Vortex wheel. Although the performance of such models correspond to the basic versions, they are distinguished by increased resistance to clogging and a technological control system.
Espa circulation pulser
If the Vigila series is focused on solving business problems within the framework of garden and construction events, then circulation models assist in the organization of communication systems. Using pumps from the NMT, RSAN, NMTD and RA ranges, it is possible to equip a water supply complex, a sewer network, and also perform tasks related to the installation of a heating unit. The flagship circulation pump Espa is a hydraulic unit with advanced design solutions. The developers provide for such models several pumping modes with support for frequency control. In the RSAN family, designed for domestic water supply, special attention is paid to the material of the housing. For the possibility of serving drinking water, the design is made with a bronze case, which is durable and environmentally friendly.
Deep pumps
Units of this type also allow pumping clean water, allowing foreign inclusions with a ratio of up to 50 g / m 3 . Such machines can be integrated into communication networks, organize watering systems with their help, but the main purpose of such equipment is to raise water at great depths. That is, the user will be able to simultaneously remove the media and send it to the consumer. In particular, Espa well pumps, represented by the Acuapres series, are popular. These are installations with an integrated control system. The operator is able to control the check valve and flow. The immersion depth of such models is about 50 m, but the performance is not as impressive as in the case of drainage units - no more than 4 m 3 is serviced per hour. Such a sharp decrease is just due to the power output required to climb to a 50-meter height. However, if necessary, you can get higher performance. So, pumps of the Tecnopres family allow pumping 6.5 m 3 per hour.
Pump Reviews
The owners of Espa pumping equipment for the most part praise this product, noting both optimal power indicators and modern functional support. Ergonomics of such installations and a high working resource are separately emphasized. Maintenance and repair of Espa pumps most often involves the replacement of fittings for water supply, including fittings, couplings, adapters and other components. The rest of the design does not cause problems - many note the reliability of the layout of the housing and related parts. As for ergonomics, even in the middle category units are presented that have integrated automatic control systems. According to users, the adjustment capabilities in such installations are consistent with the level of a full-fledged pump station.
Price issue
The most common option, presented by drainage pumps, is estimated at 15-20 thousand rubles. depending on version. At the same level is the circulation type products. However, as functionality expands, so does the cost. So, multi-stage submersible units can be purchased already for 50-70 thousand. Vertical centrifugal units of the multi-stage type are the most expensive. These are Espa pumps, the price of which may exceed 100 thousand rubles. It is noteworthy that fully equipped stations are inexpensive compared to their competitors. A medium-sized complex can be purchased for 50-60 thousand. More technologically advanced systems are available for 80-100 thousand, but these are solutions focused on professional operation.
Conclusion
Espa designers are trying to develop the idea of a universal, but at the same time reliable and efficient pump that can solve special problems. Not every model can be called optimal, from the point of view of application in different fields, but all series have an optimized design, suitable for a wide range of tasks. For example, the Espa submersible pump can be used in almost all directions that require lifting water to a height of about 50 m. If earlier the function of such units was limited only to lifting the carrier, then in modern versions the equipment also copes with its distribution and supply to the consumer. Another thing is that in the process of performing several work steps, productivity drops noticeably. For those who do not want to lose in this indicator, multistage models are recommended in which individual nodes perform specific tasks, optimally sharing the load and maintaining the pressure head.
