The difference between DVQ series and SVQ series vane pumps

The DVQ and SVQ series are both hydraulic vane pumps, but they have some differences in design and application:

 1.Design structure: DVQ series has a double pump structure, consisting of two pump heads, one of which is used for oil supply and the other for oil return. The SVQ series has a single pump structure with only one pump head. This design difference allows the DVQ series to provide both oil supply and oil return functions, while the SVQ series can only provide oil supply functions.

 2.Scope of application: Due to its dual-pump structure, the DVQ series is suitable for hydraulic systems that require simultaneous oil supply and oil return functions. They are commonly used in applications with double-acting hydraulic cylinders such as excavators, loaders, etc. The SVQ series is suitable for hydraulic systems that only require oil supply function, such as industrial machinery, agricultural machinery, etc.

 3.Performance characteristics: There are also some differences in performance characteristics between DVQ series and SVQ series. Generally speaking, the DVQ series has higher working pressure and flow capacity and can provide greater hydraulic power. On the other hand, the SVQ series usually has smaller size and weight and is more suitable for some applications with limited space.

It should be noted that the specific models and configurations of DVQ and SVQ series may also be different.
