Which option correctly identifies the ultrahigh pressure pump?

• A. Less than 500 psi
• B. 500-1100 psi
• C. 1100 psi or greater
• D. 85-100 psi

Answer: (C)

Ultrahigh pressure pumps are defined by delivering pressures at the very high end of the range, specifically 1100 psi or greater. This higher pressure enables certain emergency tools to generate the force they need quickly and with compact components. The other options stay below that threshold: under 500 psi is a low or standard range, 500–1100 psi is a mid-range that doesn’t reach ultrahigh, and 85–100 psi is far too low for these applications. So the correct identification is a pump rated at 1100 psi or greater. When working with such pumps, always use hoses, fittings, and relief valves rated for the pressure and operate within the tool’s safety specifications.
