Hello friends, as I always turn to your kindness and knowledge to overcome problems that arise. I need a board diagram for a three-phase water pump of 10 HP, very complete, manual / automatic, with a selector valve for pump1 and pump2, and connected to the pump. Attached plate of it. Thank you

Hi. I leave you a typical application diagram like the one you mention. Although this is monophasic, what changes is that the contactor is powered by the three phases. At the exit of this you can place a motor guard. As for the selector key you have the option of placing a power one that selects one or another pump. This will prevent you from doing double control circuits since it is much cheaper. The value of the contactor, the motor guard and the selector key must be suitable for the motor power. regards

Thank you very much for your prompt response, you are already directing me, on the motor plate says 19A, I wanted to raise the question but I can not or do not know how to do it is a 10HP engine of an apartment tower. They ask me something very complete as being with indicator lights of which pump is working, manual or automatic command and manual selector key for pump 1 or pump 2, if you had something like that it would be of great help I also appreciate your response.

The circuit you must apply is the one I left you. For the manual / automatic option you must use panel keys and to select the one power pumps. The contactor must be a minimum of 25 amps and its coil at 24 volts. The neons would be of the LED type, 220V for the three input phases and one of 24 volts to be connected in parallel with the contactor coil that indicates when the engine is running or at least powered.

Hi In this manual of my authorship https://www.yoreparo.com/electricidad/electricidad-del-hogar/manuales/5765964/instalacion-electrica-de-bombas-para-elevar-agua You have a diagram for two pumps with automatic switching in the event of an overload failure of one pump passing to the other and leaving a warning signal overload failure and manual switching to switch from one pump to the other at your choice In your case you have to evaluate if you need a triangle or soft Star starter Cheers

Hello elektomaq great manual, I tell you, as you will notice that three-phase motors nothing, but I am sure that with the help of capable and kind people like you and the boys of me I repair that they always helped me to get out of the way, I am going to achieve. The board thanks to your manual I think I have almost resolved, my biggest question is how to connect the pump, unfortunately I do not know how to upload images, it is a Pedrollo 2CP 32 / 210A 10HP. On the plate it says where is the drawing of triangle 380 / 400V 16A and where is the drawing of the star 660 / 690V 9.2 A. Thank you

Only for supply voltage 380 / 400V the connection is triangle, in the manual it explains how to do it, it is necessary to evaluate if it requires triangle star starting for which it is necessary to incorporate that circuit to the original
