FAQs
What determines the efficiency of a pump?
Efficiency depends on impeller design, motor performance, system layout, fluid properties, and pump speed. A well-sized pump reduces energy loss and improves output stability.
Why do pumps experience cavitation?
Cavitation happens when pressure drops below the vapor pressure of the liquid, creating vapor bubbles that collapse inside the pump. Proper suction head and flow management help prevent this issue.
Are variable speed pumps useful in modern systems?
Variable speed technology helps pumps adjust output based on real-time demand, which improves energy efficiency and reduces stress on system components.
How often should pumps be inspected?
Regular inspections are recommended based on operating hours and fluid quality. Periodic checks of seals, impellers, bearings, and vibration levels support long-term reliability.
