Whirlwind SN-50

Advantages: Easy installation, cost-effective, long cable and high performance.

Disadvantages: Sensitive to sand.

Comment: On my personal plot I use this type of pump for irrigation, I have it installed in a well. It has good pressure and a stainless steel body, I have been using it for about a year. I can say from my experience of use that it is quite economical.

Advantages: 1) Very quiet. If before that there was a vibration pump and quietly hummed from the well, then this one is practically inaudible. 2) Fine mesh at the inlet protects the pump from being clogged with sand and stones. 3) Stainless steel body. Fasteners - very good galvanized. 4) Simple and indestructible design.

Disadvantages: 1) The power cord is short. The pump has a head of 40m, which theoretically allows it to be installed in wells of the appropriate depth, but the cord is only 17m. You think, "Ha, you think, I'll extend the cord and the problem will disappear." But no, the problems will only begin. If you cut the cord, what is not a reason for refusing the warranty? And if the cord is not cut, but is built up according to the mind, unscrewing the old cord from the starting box and inserting another one there, connecting it to the free ends on the cord? It's a good idea, except that the manufacturer carefully stuck a sticker on this box with the following content: "Damage to [this seal] will void the warranty." Excellent insanity! 2) The coarse filter mesh rusts.

Comment: There was a simple vibration pump Aquarius-3 in the well. He stood and, in general, coped with his work. But there was no pressure from it even on the 1/2 "pipe. I decided to change it for something more frolic. I chose for a long time, eventually chose this one. The result is obvious, from the 32nd pipe (at the exit from the head there is such a pump) the pump gives out quite a decent pressure, Although not ideal. For irrigation as a whole it is enough, to collect water all the more, but after a couple of years I would not refuse a little more pressure. A well with a depth of about 25 m. Without any problems, it was installed in the well in one person along with the cable Last year, in the fall, I carried out the first revision in 2 years. I also got it in one person, then I also installed one. The well is a little coated, the mesh at the entrance is a little clogged with chalk. When turned on to idle in the air, it began to publish what strange sounds, I decided to disassemble and find the cause. It is easy to disassemble. The pump is not rusty, the fasteners, oddly enough, are also whole (which by the way cannot be said about the cable on which the pump was hanging). The reason was the axial runout of the impeller. Perhaps a little chalk (less 0.1mm) suction silt impeller and there was a backlash, but this is not certain. As a result, I put it back together, it does not affect the pressure in any way.

Advantages: Brass, decent power.

Disadvantages: No

Comment: Installed last year after drilling by the company's specialists. Normal supply pressure to a suburban cafe, connected through a hydraulic accumulator with automatic activation when water is taken. After the thaw, they were removed for inspection, while there was no rust. At the dacha there is a similar Wilo model, while I don't see much difference - for those who love foreign brands.

Advantages: Rise of water to a height of 50 m, stainless steel body.

Disadvantages: No

Comment: The pump was installed in the country, for a well, no problem. Everything is conveniently provided, there are special rings for attaching the cable, for lowering and lifting. There is a thermal relay against overheating. We had a couple of times it was littered with sand, and a protective device was triggered, cleaned and works again.

Advantages: smart, good equipment, long cord.

Disadvantages: no.

Comment: the upper water intake is a big plus for me, since I bought it in a summer cottage well, lowered it almost to the bottom, while I'm not afraid that it will pump something extra, such as sand, there is a fine mesh. a powerful, 100-liter hydroaccumulator pumps up quickly copes with the task, so I recommend

Advantages: Ease of use, cord length, quiet, well worth the money.

Disadvantages: not detected

Comment: The pump is used in the country, it copes well with the supply of water from a well.

The pump copes with its task, the declared characteristics are reliable - it specially timed the time and productivity, it works quietly, the vibration is minimal.

Advantages: small diameter, quiet operation, good water pumping

Disadvantages: did not find

Comment: I drilled a 17-meter well at my dacha and purchased such a pump. It works quite well as long as there are no complaints. 2000 liters per hour pumps precisely. The case is made of stainless steel, quite sturdy. The motor is protected against overheating by a thermal relay. Electricity is consumed within reasonable limits.

Advantages: stainless case, overheating protection, long cable.

Disadvantages: Didn't find

Comment: I have been using it at the dacha in the well for a couple of years, I am satisfied with the work. The hull is unharmed, I always inspect it when I get it out to clear the mesh from the sand. The water pressure is good, it does not consume much electricity. The overheating protection has tripped once and the pump was not completely submerged in water

Advantages: overheat protection.

Disadvantages: Not found.

Comment: We bought a pump on the advice of a gardener we know. For 3 years of work there were no interruptions, everything is fine. Sometimes it is necessary to water without interruption for several hours, the pressure is sufficient and economical on electricity. Be sure to ensure that the water level always covers the pump, since the engine is cooled by being in the water. The husband periodically makes a preventive examination and cleans the net for water intake from silting.
