[PDF]Vacuum Pumps Common Problems and Troubleshooting o Pump running at a speed above the required speed. Leakage If the seal water is leaking from the pump, a careful observation of the exact location of the leak and the quantity of the leakage should be carried out. Most likely areas of leakage are: o Gland packing area - It can be resolved by tightening the packing and if leak still persists,
[PDF]THE MISUNDERSTOOD CHECK VALVE - DFT® Valves Factors affecting check valve seat leak-age include reverse pressure, medium, and what the seat material is made of, such as metal or elastomer. Metal sealing surfaces generally will allow some leakage while elastomers such as Buna-N and Viton provide bubble-tight shutoff (zero leakage). Because of this, elastomers should be considered for
[PDF]Guidance for Field Hydrostatic Testing Of High Density The hydrostatic pressure test is a leak test intended to validate the integrity of the pipeline. The test pressure is never less than the designed operating pressureThe maximum hydrostatic test pressure is based. on the pipeline component with the lowest design pressure rating. The hydrostatic test pressure is usually between 1.25 times the nominal
