For applications that require a high output or just high pressure in general, a multi-stage centrifugal pump might be the right pump for your needs.
To design a centrifugal pump with a single impeller developing a differential pressure of more than 150 PSID between the suction and the discharge is difficult and costly. A more economical approach to gaining the same results is to go with a multi-stage centrifugal pump.
A multi-stage centrifugal pump is a centrifugal pump that contains two or more impellers: either mounted on the same shaft or different shafts.
Here’s a visual example of series and parallel impeller set-up:

Note: when connected in series, the impellers don’t have to be in a square shape, they just have to be connected.
|Higher efficiency||Many parts inside the casing to maintain and service|
|Higher output power (PSID)||Parts inside the casing are difficult to get to|
|Various and customizable build||Expensive initially and to maintain|
