Purchase vibration submersible water pump. What to look for?

Vibrating pump type "Little Boy" - the most versatile and inexpensive pump for the cases when you need to pump well from silt and sand, to pump water for irrigation, etc. On the market today there are many brands (except for TM "The Kid"): "Bavlenets", "trickle", "Aquarius" and etc ...

The design of all the same. The pump device easy. There is a lower water intake is high.

At first glance, there is nothing to break. But the one who was in the service center for repair of such equipment should be pay attention to the large number of repaired pumps of this type. So what's up? Why did they break? And they break down? How to select the best or the most reliable maintainability? I will try to convey their views and brief experience.

As a person who has acquired the third submersible pump (different brands) and their regular reconditioning, I can tell which model to purchase preferred criteria for reliability and maintainability.

I'll tell you first about the breakdowns, which I came across. With electrical breakdowns I have not encountered. The coil core in the pump is filled with epoxy resin and neremontnoprigodna. Burnout - just buy a new one.

But the breakdown of mechanical parts - many. The first criterion, which influences the long pump work - is reliable assembly.

The first failure of a series of unreliable assembly, that I encountered - Release the lock nuts, pressing the shock absorber to the anchor. It is hidden behind the clutch.

The pump is simply ceased to create water pressure. Not yet made it out completely - and did not understand the reason. This loosening of the nuts on the anchor rod is still distorted, because stroke increased.

Here it is the cause of failure. Once it is shown on the pump TM "brook" when I stock. But it was just so.

When assembling for some reason placed under the piston thin washers.

They mulled stock. Once he cut off - welded. Instead, I placed a nut of suitable diameter. You can search and sleeve.

Because of the free stroke on the piston rod (poorly fixed) - divides the sleeve on which it is located.

In general, the assembly of TM Bavlenets poor and fines in the design of its components and lack of thought leading to breakage. Especially all that quickly manifested in severe operating conditions - with the rise of water with sand at the pumping wells.

Next failure - a premature wear of the sand body:

Coarse sand accumulated in front of the piston and as an abrasive wipe the case. The housing in this part under the piston has an insufficient thickness

Manufacturers could make the body thickness in this part of the greater.

Inside the contact place with the piston housing izedaetsya sand and the pump ceases to produce pressure.

Sand "eats" intake holes. The valve stops working.

If there is no sale of spare parts for these types of pumps. And on TM and TM Bavlenets brook I found parts (caps) in Krasnoyarsk, we have to brew the housing, or to buy a new pump.

And that was done. Third Steel grade pump Aquarius-3 (advised master during well drilling flushing). He is reliable (the build quality is higher), but slightly more expensive counterparts. And sales have removable covers (160 rub. / Pcs.). But due to the fact that the plastic cover - wear them is more intense.

Moth inner surface of the cover. Change the cover is possible without problems. The cost of it is low. It's in my water and sand (at pumping wells). Those who have water without impurities - the pump will last much longer.

Well, and the pressure it creates a little more. This is evident by the water jet - the rise to 33 m.

The piston rod is fixed to reliably thrust washers stronger than in other models.

But there is one drawback. Because Plastic - a softer material than metal, the water intake portion stuck in the holes small stones:

Need a mesh permeable sand but not giving small stones to hammer holes, reduce the pressure and wear the cap. This refinement I'll do in the near future.

Output. Personally, for myself, I opted for the brand Aquarius-3. Not advertising, but only my opinion. At the pump more reliable and more powerful assembly of small parts, posing a greater water pressure, low-cost removable cover. A last point - overriding. Learn first, whether it is available for sale in the shops or service centers!

Initially refused his purchase just because of the plastic cover. But it turned out that it is more profitable to buy replacement cover or seal their soldering iron (it also did) than to buy a new pump. Hopefully, this is my opinion will help you in choosing this type of pump.

P.S. How to bleed the well (the water will be as bright and without sand), you need to purchase a centrifugal pump. He does not raise his vibration silt and sand does not cause the output of the filter through the annulus.
