Review on π¦ Grundfos SCALA2 98562818 3-45 AVCBDF 1x115V 60Hz Auto Water Pressure Boost Pump by Wiktor Wasilewski α
I am amazed! It was definitely worth the money!
Bought SCALA2 to replace MQ3-35. The pump has worked for 10 years. The control board has deteriorated, in the replacement of which I stuck a simple automation (PM / 5-3W). and the old pump started working again. Regarding the new SCALA2: I put it on the same shallow Abyssinian well 13 meters with a mirror 1.5 meters, with which MQ worked. Gives excellent pressure with less power 550W -Scala2, 850W - MQ. pressure scale in the middle. one inch hose into the well, reinforced with food, with a 3/4 check valve at the end (an inch did not fit into the pipe). I understand that the pump is strangled, but without an alternative. consumers: shower, two sinks, toilet. despite the variable pump, I try not to turn on more than two consumers at a time. Attention during installation: choose only reinforced hoses (ordinary rubber ones will shrink and close the flow. Place the suction hose on a sealant/fum tape, etc. due to air suction, the station may get up by mistake dry running!
- 1) quiet at medium speeds. 2) quickly mounted (nuts at the inlet-outlet are tightened by hand). That is - to remove the case for 1 minute. 3) variable pressure. holds 2 taps with the same pressure (MQ did not know how). 4) the pressure is stronger than that of MQ even at low feed rates. 5) voltage protection (when turned off, the indicator lights up for a couple of seconds voltage) 6) protection against possible leaks and dry running (cut off, but will not let the motor burn out) 7) 5 years warranty! (although the question is debatable here, whether sand that got into the pipeline or too strong a power surge will be a guarantee) 8) Protection class IPX4D - means condensate and accidentally spilled water are not terrible.
- 1) at high (last) speed it is louder than MQ (but the middle pressure is enough) and there is almost no noise. 2) too smart. Accordingly, there are a bunch of sensors that can "zakosyachiit" from time to time. is it possible to disable or block it is not clear. although it is difficult to call it a serious minus. 3) the price is probably not very pleasant.
