What Is The Difference Between Single Impeller And Double Impeller Water Pump

What is the difference between a single impeller and a double impeller water pump? The biggest difference between the single-impeller and double-impeller water pump is the difference in name, one is single impeller work, and one is double impeller work, the shape and size of the pump impeller is the main factor of the performance of the pump. From the perspective of the impeller, the flow rate of the single impeller and the double impeller must be greater than that of the single impeller. In terms of manufacturing cost, the cost of the single impeller is lower than that of the double impeller. There are many differences. Let's take a look at the differences!

1. A single impeller pump means that there is only one impeller, which has the characteristics of small flow and high pressure. The characteristics of double impellers are opposite to those of single impellers, with large flow and low pressure.

2. The flow rate of the single-impeller water pump is smaller than that of the double-impeller water pump, and the head of the single-impeller water pump is higher than that of the double-impeller water pump. The structure of the double-impeller water pump is symmetrical, the axial force is balanced, and the operation is more stable than the single-impeller water pump;

3. In terms of cost, the cost of a single-impeller water pump is lower than that of a double-impeller water pump, because the double-impeller has two impellers, so the cost increases, and naturally the price of the double-impeller will be higher than that of the single-impeller;

4. In terms of structure, there is no difference between the two types of impellers. The single-impeller water pump has only one impeller, which is sucked from one side, while the double-impeller water pump is composed of two back-to-back impellers. The fluid medium of the pump is imported Into the volute of the pump body;

5. The application scenarios are different. Single-impeller water pumps are more used in farmland irrigation, and double-impeller water pumps are more used in water supply and drainage of mines, cities, and power stations.

The single impeller and the double impeller water pump actually have their own uses. When purchasing a water pump, you must understand your own needs.
