Positive displacement pumps create flow and if that flow is blocked, the pressure in the system downstream of the pump builds rapidly. If there is no pressure relief valve, the pump will keep generating additional pressure. Pressures several times the designed operating limit can be attained in seconds.
A pressure relief valve is needed to 1) protect the equipment, 2) protect from spills and 3) protect the operator. A pressure relief valve will enable you to create the rated flow without raising the pressure above a set design point. Crisis averted!
