High-pressure pumps
A high-pressure pump is a centrifugal pump with a head of approx. 200 to 1200 m and a maximum operating pressure of up to 600 bar. Pumps for larger heads and pressures are referred to as ultra-high pressure pumps. High-pressure pumps usually serve to transport water or other fluids from a lower to a higher level.
