How should conveying capacity be distinguished from shear action in a commercial food emulsifying pump?

Define flow rate and head separately from shear effect because pump type and rotational speed govern different performance characteristics. A sample demonstration is useful, but continuous production data is needed to verify repeatability and practical capacity. The supplier should identify any capacity limit caused by product temperature, moisture, particle size, or other material properties. For critical parameters, require signed records from both parties and retain the original data with the order documents. For equipment with change parts, list every required component and its adjustment range before placing the purchase order.
