Which submersible pump from the Aquarius series to choose for irrigation?
Good day! For 13 years now I have been using the submersible pump “Aquarius 1.2-50” with a flow rate of 4.3 m3 (“Promelectro”, Kharkov). At the moment, the conditions and requirements for the pump have changed. For watering not small areas of the garden - bought 2 pcs. Sprinkler “Presto PS 6015” (from 3 to 4.8 atm. and a volumetric flow rate of 3 to 4 m3.)
In total, by volume of water we get a minimum of 6 m3 (8m3) With the outlet pressure, everything is fine, but with the volume it is a little lacking. The depth of the well is 10 meters + for a rise of 3 meters. Total - 1.3 atm. Losses in the PND are 10 atm., We do not take into account the length of the highway specifically for sprinklers, we get no more than 20 meters.
It is necessary to press the lower sprinkler tap slightly so that the 2nd one works correctly (from above). I am considering two pumps from the same series of pumps "Aquarius". The first is the Aquarius 1.6 -40 pump (5.6 m3, water. pole - from 40 - 68 meters, power el. engine - 2400 W). The second - “Aquarius - 1.2 -63” (4.3 m3 , water. a pillar from 60-90 meters, with an electric power. engine - 2080 W).
Question: which of the given options will be more suitable in my case? I will consider your options too! The total length of the PND highway (from the well to the house) is 100 meters.

Good afternoon! Considering the data you have provided (the length of the line is 110 meters, the optimal values of the water column are 1.5 atmospheres, the lift height is 15 meters) we calculate the optimal characteristics for the pumping equipment. As a result of the calculations, we obtain: the minimum pressure is 44 meters, the pressure is 4.3 atmospheres. The second metric can be shared between multiple devices. If you are going to buy 2 pumps, then the minimum pressure of each should be - 44 meters, and the pressure created - 2.2 atmospheres.
The “Aquarius” pump range includes units of the BTsPE series with a maximum immersion depth of 10 meters. The following models have the required pressure: BTsPE 0.5-32 U (60/47) worth from 9 thousand rubles, BTsPE 0.32-50 U - from 12 thousand rubles. The second option will have a higher productivity (liters per second), therefore, watering with it will be faster. It is not advisable to buy more expensive modifications if you do not plan to expand the irrigation area.
