Operating conditions such as hydraulic axial force, shaft deflection, and thermal expansion require a minimum initial clearance. Routine adjustment will compensate for normal wet-end component wear.[/sidebar] Q: Our pump is running fine. Why […]

Airlock is simple but devastating. The main symptom of airlock is reduced flow. When you have reduced flow, you have reduced production. And when airlock is severe enough, it can stop production altogether. For a simple but clear example of what happens, watch the video below: The problem is that air is essential in mineral processing […]
If you’re like most operators, you have a slurry pump stuffing box to prevent fluid and material from leaking out of your system. While this isn’t the only design available, a stuffing box is more economical and more forgiving than dynamic expeller and mechanical seal types. For these reasons, the stuffing box tends to be […]
