1. PSI and GPM Ratings Look for models with a PSI (pounds per square inch) rating between 1200-2000 for safe and effective car washing. A higher PSI might be too aggressive and could damage the paint. The GPM (gallons per minute) indicates how much water the unit can deliver; a higher GPM leads to better cleaning efficiency.

The design of the volute is crucial for the efficiency of the pump. A well-designed volute minimizes flow separation and turbulence, ensuring a smooth transition of the fluid from the impeller to the discharge pipe. The volute shape is typically spiral, which facilitates a uniform flow distribution. If the volute is improperly designed, it can lead to inefficiencies such as cavitation, vibrations, and noise, significantly affecting the pump's overall performance.
