How To Deal With The Common Problems In Water Pumps In Hungary
When you buy water pumps from Grundfos pumps dealer in Hungary sometimes you may face some problems when using them. You must not take it to mean that the szivattyú (pump) is of poor quality. But rather that there could be slight technical adjustments that you need to do. The common problems with pumps and the best ways to deal with them are discussed.
Water szivattyú (pump) That Is Not Priming
A common problem that users experience when buying water pumps from Grundfos pumps in dealer in Hungary, is that the szivattyú (pump) fails to prime after a time period of three minutes. The possible reasons for this situation are the housing of the szivattyú (pump) not being filled with water, if this is the case you have to fill the housing with water. Another reason is the static suction head is too high, in this case you have to lower your szivattyú (pump) so that it is closer to the water. Sometimes the suction hose can be too long, in this case you have to reduce its length. If the suction hose is leaking, you have to repair it or the coupler seal. If the strainer is plugged, you have to clean the strainer and free it from debris. You can do this by submerging in a bucket.
Low Discharge Capacity Of szivattyú (pump)
If the discharge capacity or pressure of the water szivattyú (pump) in Hungary is low, that could be because the discharge hose is restricted or long and that cause excessive head loss. You can either increase the hose size or you can shorten the hose. It can also be because the impeller and the volute is worn. You have to either use a trash szivattyú (pump) or szivattyú (pump) only clean water. Sometimes the discharge pressure is low because the maximum engine speed happens to be too slow. The reason for that could be because the engine lever is not in a fast position.
If Water szivattyú (pump) Cavitates
Another issue experienced by most szivattyú (pump) buyers in Hungary is the grinding noise and the impeller that is worn away because of pitting. This could be because the strainer is blocked. The remedy for this situation is to clean the strainer from dirt, dust and debris. Another reason is because the static suction head is great, or the diameter of the hose is too long or small. In this situation use the shortest hose and the diameter must be equal to the suction port of the szivattyú (pump).
