Top 10 pumps for well

Having simplified the construction as much as possible, Grundfos managed to make the price very attractive.Unlike the more expensive SBA series pumps, there is no built-in automation (an external unit can be purchased and installed separately if desired), and the price due to this has decreased by about a quarter. The 800-watt motor allows the pump to operate with a head height of up to 30 meters, while its performance is 20 liters per minute. A good option well pump, if in a private house a decent water flow, and even watering the water is also needed. The main thing is to have a well flow rate.

Unfortunately, the "sand resistance" of Grundfos is much worse than that of the reference Pedrollo in this respect - exactly three times. Keep this in mind if the pump is lowered deeply, and there is enough sandy turbidity in the well.

The pump is assembled decently and does not cause problems during operation, although it may seem expensive. The combination of an 850-watt electric motor with six pump sections allows it to work confidently with a decent lifting height, creating good pressure - and the water from the tap will go as it should, and the watering will remain with a reserve.

But for this money, I would like to have at least protection from the dry run out of the box, and not to install it separately - after all, this is not Grundfos, where a certain overpayment for the brand in price is clearly felt with current prices. Moreover, the pump is assembled in China, which in itself means lower costs than the Italian Grundfos SB 3-35 M.

Despite the "yellow" origin, the pump is not bad in quality, besides there is a float, and protection against dry running. At the same time, the motor is oil-filled for better cooling during long-term operation, and the stated resistance to sand is at the level of the actual Pedrollo reference (150 g / m3). He will provide a cubic meter per hour even with a seventy-meter head, he will be delivering more than three “cubes” to a height of 20 meters. So for deep wells such a choice would be quite justified.

The only thing worth considering is the quality of the seals; over time, they sometimes start flowing oil into the water. So you have to remove the pump for the bulkhead, and thoroughly flush the pipes to get rid of the "rainbow" on the surface of drinking water. On the other hand, it will signal a leakage before the water "kills" the electric motor. Therefore, if there is no money for Pedrollo or Grundfos, one cannot say that the choice of “Belamos” will be so unsuccessful.

A good "middling", which is relatively inexpensive, and pumps well: up to 85 liters per minute, while the engine power is moderate - 480 watts. The pump tolerates a large pressure, so it can work quietly in deep wells.

The case and the mesh filter are made of stainless steel, the impellers of the multi-section pump are made of polycarbonate. We especially emphasize decent resistance to sand - up to one hundred grams per cubic meter, this is a very good indicator even in comparison with many "eminent" competitors - the same Grundfos will not withstand such water for a long time.

We note, however, and the design minus is the motor protection here is current (and not thermal fuse in the stator winding), and it works when current increases to 17 A: this corresponds to no less than 3.7 kilowatts of power! Of course, the margin on the starting current should be, but not the same.

750-watt “automatic” is designed for water supply of a private house even from deep wells - already with 45 meters of lift, it “masters” 10 liters per minute, with a ten-meter rise - more than 80. Built-in automation with flow and pressure sensors allows it to work completely “independently ”, While even a hydroaccumulator, from the experience of the owners, is not necessary to buy: the pump provides good stability with drops in water consumption. During long-term operation, engine cooling with water flow becomes an additional advantage.

However, this pump does not compete with Grundfos SBA. Firstly, it is purely constructive: plastic is more here, which is not good, as the Germans like to say in domestic films. Secondly, it is more sensitive to voltage drops, and here we again resort to the experience of those who have already acquired pumps of this series: it is worthwhile to put a stabilizer. Thirdly, the fastening of the cable to the plastic handle, and not to the metal eye, is somehow more familiar with cheap pumps, here I would like to see a more reliable solution. If we choose between a “thousand-two” and a “thousand” Divertron, then we will give preference to the model 1200: it allows for a deeper dive into the well relative to the water level, which with such a performance will not be superfluous - there is no float switch here.

Well known since the Soviet times, “The Brook”, now renamed the plant from the city of Livny to “The Kid”, is not particularly necessary, it is a low-power vibration pump designed for use in full-flowing wells. Of course, for such a price it is simply no place further - even the water level will have to be monitored independently, not to mention thermal protection. But the energy consumption is a penny (240 W), and it costs less nowhere. It is worth noting that the windings became more powerful than the original “trickle”, which gave its plus to reliability.

According to the characteristics, it is not so bad - it can calmly pump water over a large horizontal distance (important when watering), we tolerate impurities. Its maximum performance reaches 25 liters per minute. In a word - a good and inexpensive "summer" pump for irrigation with a well-known design in case of repair.

How to call it - pulling or koops? The construction of the “Bavlents” is brutal - these are actually two coupled “Stream”, as a result, the pump has both the upper and the lower intake. Well, at least, the site of the manufacturer does not lie, speaking of "a model that has no analogues": nobody really thought of that.

Impressions of the pump controversial. Of course, he has better performance than a single “grandparent”, and good resistance to sand ... But the vibration level, which already became a common problem for pumps of this type, is also greater, and when the water level falls, the upper section, “ Slipping "air, will not work and lower. So yes, some kind of “catopes” came out.
