A high pressure pump is broadly defined as any pump that can generate high discharge pressure, generally in excess of 800 psi. Pumps that generate pressures between 800 and 3000 psi are known as moderate high pressure pumps, while pumps that generate anywhere between 3000 psi and 5000 psi are known as very high pressure pumps. Apart from these pressure levels, there is another category of pressure pumps known as ultra high pressure pumps that generate pressures significantly in excess of 5000 psi, in the range of 10,000 psi to 40,000 psi
