Positive and negative guide vane water pump

The positive and negative vane pump is a common centrifugal water pump, and the blades on the impeller are divided into two types, positive and negative, so as to be able to adapt to different working conditions. Positive blades are typically used for high heads and low flow rates and can provide high heads; Reverse vanes are suitable for low heads and high flow rates, providing high flow rates.
 
The impeller of a positive and negative vane pump consists of alternating positive and negative vanes, which rotate in opposite directions. During operation, according to the requirements of different working conditions, you can choose to use positive or reverse vanes to achieve the best results.
 
Positive and negative vane pumps have the advantages of simple structure, reliable operation and strong adaptability, and are widely used in pump systems in industry, agriculture, municipal and other fields.
