Review on Borehole pump Aquarius BTsPE 0.5-40U (720 W) by Stanislaw Plonka ᠌

So, 4 years have passed in operation and we can draw conclusions . Water supply in a private house, a well of 7 rings, living all year round. Expansion tank 50l, pressure in the system is set to min. 2 atm max 3.5 atm, water intake - 2 bathrooms with showers + kitchen. Between the pump and the system there are 2 20BB winding filters for 10 and 5 microns. The pump is installed in a well at a depth of 6 rings from the ground level, the highest water intake is at a height of 5.5 meters from the ground. The check valve is installed directly on the pump. The pump has been working like clockwork for 4 years now, calmly pulling a pressure of 2.3 atm at all open points of water intake. According to the maximum duration of continuous operation in this mode, I did not specifically measure it, for 30-40 minutes at peaks it works for me without problems. Although I have a lot of sand in my water (it can be seen from the filters when they are replaced), this does not affect the operation of the pump in any way - there are no performance losses, no noise. Perhaps it was worth installing an external filter on the pump, but the hands reached it) During a recent external examination, no rust was found anywhere - the pump looks like new after wiping with a cloth. Several times the water went below the pump - I did not have an idle relay installed, but the pump itself turned off due to overheating. When immersed in water, it calmly turned on and worked on. When I bought it, the price, of course, was 2 times lower than it is now - but I can recommend buying it even for this money. The pump turned out to be really reliable and of high quality, which is called "set it and forget it"
