I want to buy a jet150 pump (Chinese peak of famous trademarks, well-known in Guangdong province), come back after the discovery deceived, found that the pump impeller is aluminum instead of copper. They want to know how much difference in price? There is no impact on the performance of aluminum impeller and pump, water quality of life?Aluminum impeller will not soon be damaged by cavitation, home pumpIn addition, the pump running 30 minutes later, the motor heating seems a little serious, about 6 or 70 degrees, is not normal?(in fact, the pump has been bought and used.)
The 1. pump is seven wire copper wire or aluminum?2. is the casing of the submersible pump aluminum or iron? Is the impeller copper or aluminum?3. is the tightness of the submersible pump good? It must not leak4. what is the no-load current (the smaller the better) and the efficiency (the greater the better)?5 sectional area and material of cable
3. copper hardness and other physical and chemical properties are much better, so,4. copper is 2-3 times more expensive than aluminumNow the water pump quality products are many, the most critical you have to know the following points:
The difference between aluminum impeller and copper impeller is mainly:1., the resistance of water to copper is smaller than that of aluminum, so the copper impeller is efficient2. copper has much better corrosion resistance than aluminum
