BB4 Boiler Feed Pump – Bearing Housing Redesign
PSS Engineering Solutions – Enhancing Reliability Through Innovation We are pleased to showcase another successful upgrade delivered by the PSS Engineering team—a comprehensive redesign of the bearing housing for a BB4 Boiler Feed Pump. The original housing required cooling water for operation, but suffered from poor internal circulation. Using our 3D scanning and 3D modeling expertise, PSS reverse engineered the […]
PSS Upgrades Kingsbury Compressor Bearing
PSS Upgrades Kingsbury Compressor Bearing PSS was recently awarded a job to upgrade a 6” Kingsbury thrust bearing system, significantly improving both thermal performance and temperature monitoring for high-speed rotating equipment. This project involved replacing the original steel center-pivot pads with copper offset-pivot pads, and upgrading the instrumentation by adding a second temperature sensor to […]
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. […]
PSS CFD Study Reveals Critical Wear Risk in Absorber Recycle Pump
In critical services like absorber recycle pumps, small design flaws can lead to big reliability problems — especially in slurry handling environments with high solids and acidic exposure. At PSS Group, we recently performed a complete reverse engineering and CFD validation on an absorber recycle pump as part of a refurbishment project for FGD service. […]

Is C10 the Right Barrier Fluid for your Seals?
C10 oil (ISO VG 10) is widely used as a barrier fluid in API Plan 52 and 53 seal systems due to its low cost and availability. However, its low viscosity, high evaporation rate, and poor thermal stability make it unsuitable for many critical applications. Using C10 where it is not recommended can lead to […]
