We then reduce the RPM in 250 RPM increments noting the flow at each point. We then run your pump up to 4000 RPM and achieve that maximum pressure and record the flow. Your theoretical maximum system pressure is calculated using your nozzle and main jet combination. In addition to the two standard tests, cleaning and inspection described above, a pump flow profile graph is generated. We use a thermal printer so it's impervious to smudging when exposed to water or fuel.Īdvanced Pump Profile - This complete pump flow profile gives you the whole picture of what your pump is or isn't doing. Stick your flowtag inside your logbook, toolbox lid, the wall of your trailer, etc. To help keep you from misplacing your flowtag, ours are DECALS.
All parts are thoroughly cleaned, internal clearances reset, and a new front seal is included. Along with a flow test, pumps are disassembled for inspection of bearings, rotor, impeller, body, and overall wear. If you use a different fuel, we can deliver numbers that are real-world for your application. Our basic pump checkout includes observations under two standard conditions 1800 pump RPM and 50 PSI back pressure and also at 4000 pump RPM and 100 PSI back pressure at a standard 68F and. This means the flow number is nearly worthless! The flow of a pump against a precise known back pressure is critical to determining a safe tuneup and evaluating pump health. Some flow tags floating around out there do not specify the pressure at which the flow was measured. Standard Flow Tag - This is our most basic fuel pump flow tag.
