Initially, they wanted to take Grundfos, but the required model was not available, the seller advised Vilo Star. We bought this for an enterprise in a pipeline cooling system, it works without any special claims. Since production is continuous, the pump itself runs around the clock with rare power outages every two months. Looking at the price, I can say that he has already worked his money three times so accurately. The device is connected to the automation system, so there is no need to go to it, which means that it is rarely visually inspected. Recently I noticed a slight noise in the new state, this was definitely not the case, but since the case itself does not fall apart and the pressure keeps stable, no one will remove it for inspection or repair. I understand, of course, that this equipment is far from industrial, but that it cost the manufacturer to add pumping speed control in addition to manual, also remotely using a control signal in everyday life, such an opportunity would also be in demand. What I liked was the ability to remove and fix the terminal box with the cable entry on any of the four available sides, in this case the pump is right next to the cable trays, and this option was very useful. possibility of horizontal installation; seals and installation instructions are included; there is a casting for an open-ended wrench on the casing near the nozzles, which was helpful during installation on the pipeline; resistant to power surges; spring terminals are available in the terminal box for connection. a slight noise appeared after a few years of use; there is no remote control available. use Wilo Star-RS 25/6 month or more |
Solid German circulation pump, which is worth the money that they ask for it. Works silently, long and reliably. It operates completely silently, you set it up and forget about it. I remembered about the pump for the first time only when, due to a minor battery malfunction, the house cooled down for the first time. Before that, there was no noise from it at all. You can adjust the speed of operation depending on the temperature in the apartment. It adjusts smoothly and conveniently, I rarely switch it to maximum power, the first two speeds are usually enough. It does not fail due to voltage fluctuations. Even if the voltage in the network fluctuates to the point where the computer shuts down and the lights noticeably flicker, the pump continues to work. Good price-quality ratio. There is no hotel switch, that is, the pump shutdown system will have to be organized independently, for example, from a socket. Graphite bearings sometimes break. use Wilo Star-RS 25/2 month or more |
The old circulating pump broke down, which lasted about six or seven years. So, I had to urgently replace it. I decided to buy this particular model because I trust the manufacturer (the previous one was also Wilo brand) and it has suitable specifications. This pump is not cheap; there are a lot of cheap Chinese options on the market now, but I decided not to tempt fate and chose the German-made one instead. For now, I can say that at first glance the model is of high quality. The price, of course, is not the most attractive, but it is compensated by German quality. I think it's better to buy this pump once than to buy cheap Chinese counterparts before every heating season. The pump is compact, installation is simple thanks to the screw system. As for the work itself, there are no complaints - he copes with the tasks set without question. The manufacturer has provided three modes of operation: the difference lies only in the speed of water circulation in the heating system. In practice, it is enough to set the appropriate mode and never return to this issue. I want to note that at any speed the pump works almost completely silently. With a sufficiently powerful engine, it does not consume a lot of electricity, which is very good. The pump works great, no issues. |
