NPSH-Optimized Pumps | Cavitation Prevention & Pump Efficiency by EKG (Malaysia) Sdn Bhd

Why NPSH-Optimized Pumps Need Immediate Attention?

When Net Positive Suction Head available (NPSHa) drops below required (NPSHr), cavitation destroys impellers, seals, and bearings. This causes vibration, energy waste, flow reduction, and sudden pump failure—disrupting HVAC circulation, water treatment, and industrial processes. EKG (Malaysia) Sdn Bhd delivers NPSH assessment, pump optimization, and system modifications to eliminate cavitation and maximize pump lifespan.

Our NPSH-optimized solutions serve:

• HVAC Chilled Water & Condenser Water Systems

• Water Treatment & Industrial Process Pumps

• Fire Protection & Booster Systems

• Municipal & Sewage Pump Stations

Common Causes of NPSH-Related Pump Failure

• Insufficient Suction Head – Pump located above source with inadequate positive pressure

• Excessive Suction Lift – Long pipe runs or high vertical lift creating vacuum conditions

• High Fluid Temperature – Increased vapor pressure reduces NPSHa

• Blocked Suction Strainers – Restricted flow causes pressure drop

• Undersized Suction Piping – Excessive friction losses at the pump inlet

• Poor System Design – Sharp bends, air pockets, or undersized tanks
