In saltwater service, cyclone separators are typically fitted on pumps with a total head of at least how many psi?

Cyclone separators rely on a strong swirling flow to fling entrained solids to the wall and out of the pumped stream, protecting the pump from abrasion in saltwater service. To achieve that centrifugal action, the system must have enough energy, expressed as total head, to push the slurry through the separator and overcome its pressure drop. A minimum total head of about 30 psi provides sufficient flow velocity and energy for effective separation while keeping the added pressure losses reasonable. Lower head levels (10 or 20 psi) typically don’t produce reliable separation because the swirl is weaker and the separator won’t perform well; higher head (like 40 psi) would still work, but 30 psi is the commonly used minimum guideline.
