Stalling in a rotary compression occurs when the airflow through the compressor is insufficient to maintain the impeller's speed, leading to flow separation and a reduction in pressure. Surging, on the other hand, is an oscillatory phenomenon where the compressor alternately chokes (reduced flow) and surges (momentary reverse flow). This instability can cause mechanical damage to the compressor.

In volute casing the discharge area is more. so as per bernoulli's principle the pressure must be reduces also from the basics, pressure = Force/Area. so pressure and area are inversily proportional. By considering these two basic rules pressure must be reduces. But in any centrifugal pump, the pressure is increasing. How the velocity is converted into pressure. In my view only head is increases but how the pressure increases?
