What is the pressure range for a high pressure pump?

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

Answer: (A)

High pressure hydraulic tool systems must deliver enough pressure to generate the force needed for cutting, spreading, and other rescue actions. The typical operating range for a high pressure pump is about 500–1100 psi, which provides sufficient power to hydraulic tools while staying within safe limits for hoses and components. Pressures well below this range won’t reliably operate the tools, and pressures at or above this range can risk over-stressing equipment. Very low pressures like 85–100 psi are not used for hydraulic rescue tool circuits.
