I would like to know that a water pump or water motor which is of 1 hp what is the height from which it can pull water ? And also if there is a bubbling sound of air and no water is being supplied what does it mean ?
I will 'clarify' the question, then respond----- If you have a 1HP motor connected to a water pump,; what is its lifting capability ? (like raising the water UP from a well)... At or neat 'sea level', the very ideal (perfect) pump can lift water UP from 33 feet below. To be practical, considering in-efficiencies(losses) you should plan for about 25 feet of lift. Gurgling or bubbling of air/water is a good sign that the pump can not generate the vaccum-seal to begin the flow of water(priming process). You need to provide a way to prime the pump. To prime the pump, you need to supply a flow of water INTO the pump as it is running(water must be running backward into the well, then the pump will initiate the lifting process. To prevent the need to prime the pump everytime that you turn it on, you should put a check valve at the INTAKE orifice (the very end that sticks in the well). This will hold the column of water in the pipe; preventing it from running back into the well. (A check valve allows fluid to flow in one direction only....this must be connected such that the water can only flow UPWARD, out of the well. Good luck.....if you need further assistance, do email with more pump detail/specs. Make sure that the pump is rotating in the correct direction......
we've a Jetta and the water pump went at 30,000 miles. Its meant to very final plenty longer till the timing belt needs to get replaced. the reason they use plastic for the impeller is so if it fails it does not harm the timing belt. whilst the pump fails you may notcontinual the motorcar for any distance, the engine overheats, the warning lighting fixtures furnishings come on and thats it. in case you persevered tocontinual you might have the skill to desire to probably grab the engine or a minimum of blow the precise gasket and warp the precise, those engines are all aluminum and might't stand to be overheated.
You say that your pump used to operate properly before, so if the pump is in good condition, the lift mustn't be too great so we can rule that out. It appears to me that the gurgling sound would be made by sucking air, and for this to happen, it would be a problem on the inlet side of the pump. If the person who repaired the pump knows what he is doing, it shouldn't be the pump, so we can rule that out. That leaves the pipe and any fittings between the pump and the foot valve that should be on the end of the pipe. Try running the pump, and pouring water over all joints and fittings, one at a time, if the pump is working properly, a slurping sound will be heard at the leak. The pump will have a priming point, a screw in plug, somewhere on top of it. With the pump stopped, remove the plug, and pour water into the hole. You should be able to fill the pump right up, and the water remain at that level, without draining away. If it wont retain the water, the valve on the bottom of the pipe is either worn out or has something like a stone or gravel preventing it from operating properly. As you have disconnected this pump for repairs, it would have needed priming anyway, which is the filling up with water. It's too much to ask a dry pump to lift water any height, so maybe you don't have a problem at all. Good luck
