What is the maximum suction height for a P-100 pump?

A P-100 pump, which is a portable centrifugal pump commonly used in damage control operations in the Coast Guard and other maritime contexts, is designed to create a vacuum to draw water from a source. The maximum suction height refers to the vertical distance through which the pump can effectively lift water.

The correct answer, which denotes a maximum suction height of 20 feet, is based on the pump's operational specifications. This height is critical for effective firefighting and flooding control measures, as it ensures that the pump can draw water from a variety of sources, including from below the waterline or an elevated position.

Understanding the maximum suction height is essential for personnel to ensure that they operate the pump within its effective range. Exceeding this height can result in cavitation, where vapor bubbles form in the pump, leading to a significant reduction in performance and potential damage to the pump itself. This knowledge is vital for successful operations in emergency situations where water must be moved quickly and efficiently.
