What is the minimum required pressure for water booster pumps used in dry-mix applications at the nozzle?

In dry-mix applications, maintaining an adequate pressure at the nozzle is crucial for ensuring the material is properly dispersed and mixed. A minimum pressure of 60 psi is typically required to achieve the desired performance. This pressure level helps to ensure that the water is forcefully delivered through the nozzle, allowing for an effective mixing of water and dry materials.

Specifically, 60 psi provides sufficient force to prevent clogging at the nozzle and to ensure uniform coverage of the mixed material. It also allows for better control over the application process, ensuring that the mix achieves the consistency needed for optimal results. Lower pressures may not achieve these standards, leading to issues such as inconsistent mixing or material flow, which can compromise the quality of the application.

Other pressure levels listed may not support the necessary efficiency or effectiveness required for dry-mix applications, making 60 psi the standard minimum recommendation for this type of usage.
