A good submersible pump, output to 3/4 "hose, with a real capacity of 1200l / h (5 220l barrels per hour). With idle protection in the form of a built-in float.
Please do not waste time on this REVIEW time for those who do not have a summer residence. There is no live photograph of the pump against the background of fish, against the background of a hand, against the background of roulette, there are no photographs at all. Only practice and boring numbers.
About any packaging, delivery time, etc.I will not write. I consider this the most useless information. Buying from China = get ready to wait. The goods arrived faster than usual and in the usual bubble or something like that.
On ebay, etc., I found many cheaper options, but when I considered it taking into account delivery, it was the cheapest or one of the cheapest.
At my cottage there is a problem with the cellar. There is a key that is especially active in the offseason after rains and snowmelt. A pit in the form of a concrete well ring is filled (~ 300 l), it can be filled in less than an hour. (during drought and winter, water is completely absent). To avoid flooding supplies, a standard submersible pump is used. But the trouble is, at times when it is especially needed, the electricity is turned off and not for one day.
Purchased this pump, 10W solar panel,charge controller, old battery found. An additional role of the charge controller is to prevent the battery from sucking below the “zero” capacity when the plates are crumbling ... And everything is thrown into a long box - there is no time, there is a lot of other work in the country
But during the heat, I remembered about this pump andcame up with another application for him (for the main task I will buy another one of the same). Pump warm water out of an existing reservoir into barrels. Of the complexities - I had to come up with two weighting agents in the form of two stones and aluminum wire. The pump is constantly in the water, the accumulator is covered with a basin from the sun, the hose is stored nearby in a folded form, covered with a piece of linoleum 1.5x1.5m.
By electrical connection: The “mass” of the pump is one, and the “+” is two whole - one turns on the pump in constant operation, the second turns it on when the float is triggered. The mode without a triggered float is not clear to me. Connecting through a float is smarter and safer!
Main advantages over any other 220V pump:
1) Lightweight, compact.
2) Safe. Because I will use not only me
3) Once again safe (!) + No wires 220V
4) And again safe (!!) - because he works in water.
5) Economical in terms of energy consumption. (In an autonomous plan, when powered by a 12V battery, it is much more economical than 220L pumps)
Dimensions: length 145mm, width 83mm, height 103mm (manufacturer data)
Voltage: 12V, Current: 3A (not double-checked), Power 36W.
Real performance (almost zeroheight difference, 25m hose 3/4): 1200l per hour. The manufacturer claims a capacity of 750 GPH (US Gallon Per Hour - that is, gallons per hour) 1 US Gallon = 3.78541 liters.
Old car battery with residual15A capacity should be enough for 5 hours of operation, i.e. 6000l, which means 30 barrels of water => loaded in the spring and enough until the fall! In fact, typing 3 barrels of water, measuring on the trail. day battery voltage, I was convinced that he did not even notice these three barrels. Voltage 12.8V (full charge)
The manufacturer claims that the power is enough to raise water by + 3m. I didn’t check, but by two meters - it will definitely raise it!
ps There is no photo of the cat but it is. The usual red cat nailed to the cottage is a mousetrap!
