MAXIMUM PRESSURE-MAXIMUM FLOW
Remember that the maximum pressure and flow in a pump are irrelevant data.
Upon opening the nozzle, the maximum pressure drops immediately due to various factors: chosen flow rate, size and length of the hose, engine RPM, etc.
| The crucial aspect is for the firefighting pump to maintain good pressure under every circumstance at a chosen flow rate. The flow-pressure relation. |
In this regard, VILPIN pumps are unparalleled because they utilize the entire motor torque curve.
The same applies to the maximum flow: lt varíes based on engine RPM, size and length of the discharge hose, as well as the suction hose, depending on the installation or absence of filters and foot valves, or the nature of the pumped liquid, etc.
