Model overview based on user reviews
The Circulation Pump Optima OP25-40/130 is designed for heating systems and features a robust cast iron body, ensuring durability and reliability. With a maximum flow rate of 3000 L/h and a head of 3.7 meters, it efficiently handles circulation tasks. The pump operates quietly even at maximum speed, thanks to its asynchronous motor and wet rotor design. It offers three speed modes, allowing for energy savings and pressure compensation. Installation might require professional assistance due to its complexity. The pump is best suited for systems with clean water, as impurities could affect its performance. Overall, the Optima OP25-40/130 is a solid choice for those needing a reliable and efficient circulation pump for heating applications.
Pros
Cons
If you are sure that clean water without impurities flows through your pipes, then this model is suitable, but in other cases it is not. Good discharge height - up to 9 meters. 4 is enough for me, but it's nice to know that, if necessary, the pump can pump water to such a height. It can work in one of three speed modes. At the maximum, there is almost no noise, the vibration is also small. At the minimum, it saves energy, but it still compensates for the pressure difference. Robust cast iron body. I think that with this build quality, the pump will work for more than one year. Yes, and it looks solid, you can immediately see - the quality. Can be used in one-pipe and two-pipe heating or air conditioning systems. I bought it for heating, it copes with its tasks perfectly. Can only work with clean water. So if you are not sure about the absence of impurities in tap water, then it is better to put a filter on the pipe, so the pump will work longer without breakdowns. Difficult to install on your own, had to call the master. Of course, maybe the whole thing is in my lack of experience in such things. use Optima OP32-80/180 month or more |
The pump is good, using it for five years for sure, only sellers almost everywhere write that the maximum consumption is 150 watts, but this is not so: 1 speed 150 watts, 2 speed 230 watts, 3 speed 245 watts, written off from the label on the pump itself. I did not find them, from autumn to spring it will fall as expected. use Optima OP32-80/180 month or more i recommend it should buy |
