PSS Successfully Re-Engineers and Restores Sea Water Pump Impeller at a Power Plant in the Philippines

In March 2025, one of the six installed circulating water pump units at a power plant in the Philippines tripped due to high vibration. Subsequent inspection revealed a catastrophic impeller vane failure on a 5-vane vertical mixed-flow pump supplied by the OEM. The pump handles 16,900 m³/hr of seawater at 700 rpm, with no redundancy. […]
