Why is the ultimate pressure of my KINNEY KT300 system excessively high?
- JjohnsonlindsayAug 7, 2025
High system ultimate pressure in your KINNEY Water Pump can stem from several issues. The process equipment might be contaminated; in this case, clean it with acetone or alcohol and then pump down overnight. Leaks in the equipment or pump could also be the cause; perform a leak check and repair any leaks. Restricted oil flow, indicated by the oil level not changing with pump pressure, requires draining the oil, cleaning the external oil piping and y-strainer (KT500/850), and replacing the external oil filter if there is one. Contaminated pump oil necessitates an oil change. A malfunctioning discharge valve needs checking. Similarly, a malfunctioning shaft seal or worn/damaged internal parts of the vacuum pump will require inspection and possible repair or replacement.
