Appendix G—Troubleshooting Guide
In diagnosing pump and system troubles, record the
following data during product transfers:
1. Pressure at pump suction.
2. Pressure at pump discharge.
3. Pressure in truck tank.
4. Pressure in tank being lled.
5. Pipe size and length of suction and discharge lines.
6. Size and length of vapor equalizing line.
7. Pump speed if practical.
Problem Cause Solution
Low capacity Pump speed too slow Check engine speed and PTO on pulley ratio. Consult pump
performance curve. Use tachometer on pump if speed is
questionable.
High differential pressure Restriction in discharge piping or hose too small. Vapor
equalization lines too small or not used.
External bypass valve stuck
open or set too low
Readjust, repair, or replace valve.
Clogged strainer Clean strainer.
