PSS Restores 8.3 Meter Sump Pump
We are pleased to share with you the successful completion of a challenging pump restoration project undertaken by PSS at a major refinery in Thailand. Last year, we received a badly corroded VS4 sump pump from the refinery, with a total length of 8.3 meters and a column length below the base plate of approximately […]

Our engineering team have successfully designed and engineered our largest ever Universal Metallic Expansion Joint, with a diameter of 1.2 meters and a total length of 2.5 meters. The application of this metallic joint is on […]
PSS Introduces Boron Diffusion Service
To deal with erosion and abrasion damage inside pumps, maintenance teams typically go with tungsten carbide or Stellite coating repair solutions. PSS has been offering these services in the market for many years. But now, there is a more superior solution in the market that we would like to introduce. Boron diffusion process creates a […]
PSS Re-Engineers Pump Metallurgy
PSS recently overhauled an unsupported BB1 pump for which we had to supply completely re-designed pump components. The body of the cast iron pump was severely corroded due to galvanic corrosion. The metallurgy of the original pump was a combination of Superior and Inferior materials for the fluid pumped causing accelerated deterioration of the inferior […]
PSS Scans First Steam Turbine
A refinery in Thailand was facing a major dilemma operating their 35 year old recycle gas compressor due to their failing steam turbine driver. The API 612 non condensing steam turbine had a rated output of more than 2 MW. The main steam chest, casing, and exhaust was of A216 WCA construction. […]
PSS Upgrades Vertical Sump Pump
It is possible to more than double a vertical pump’s life by upgrading the pump repair to a “precision remanufacture”. As a result of this, the pump vibration will be reduced and can be verified upon start-up. The precision repair and upgrade cost is usually a small item in the pump’s life cycle cost. This […]
PSS Improves Gas Turbine Performance with John Crane
Heating the air inlet to a gas turbine rather than cooling may appear contrary to what we know about thermodynamic efficiencies. However, the benefits of heating intake air during part-load operation can enhance overall plant flexibility. On a typical gas turbine, output is regulated by adjusting the inlet guide vanes. However, there is a point […]
PSS Pump Saves 1 MUSD
This past month, PSS commissioned our first drop in pump – a split case double suction BB1 pump. This was a brilliant success with calculated power savings of about 1 MUSD per year. The drop-in bare pump was fitted into the existing piping envelope with existing baseplate footprints and existing 1 MW motor. There were […]
PSS Overhauls 4 Ebara Compressors
PSS recently overhauled 4 Ebara centrifugal compressors at a major gas processing plant in Thailand. The scope of work included the replacement of the John Crane dry gas seals, couplings, axial and thrust bearings. As the complete overhaul had to be completed within 15 days, PSS deployed 4 different teams for the 4 compressors, utilizing […]
PSS Converts Japanese Pump
A major water utility in Thailand recently awarded a drop-in pump replacement order to PSS. The original pump, a split case BB1 originally manufactured by a major Japanese OEM, suffered a catastrophic failure at site during restart operations. Upon opening the pump in the PSS Pump Repair Center in Rayong, our engineers witnessed severely distorted […]
