There are around 20 technical experts in total and a quiet big isolated service area complete with crane and tools for each in our workshop. 10 technician are for the in-house service and the other 10 are those who ready to be sent outside to do the technical support including commissioning, on site problem solving, technical consultation and etc.

And etc.

Quality Control & Logistic

In supporting the ISO 9001:2008 qualification and in order to maintain the accreditation, The QC department has also recently formed, by investing a quite big number of hiring experts, offices and tools. We believe, less complains against product's performance or damage would occur.

QC member's job is to do the last checking of the performance before the goods are ready to be contributed which means it plays a big role in making sure the performance of SIL products and our professionalism.

Every single unit or parts that check-in and checkout, must be well inspected. The tested units will be identified by a QC passed stickers.


PT. SIL is considered as the biggest stockiest in terms of mechanical supplier since few years back, and by the year of 2012, we have increased the capacity by re-manage our warehouse into an ISO 9001:2008 standard. The purpose in upgrading this department is because we have the commitment to provide a quick solution for customers in terms of stock.

  • CK pumps and Ulysses pumps
  • PC chains ( more or less, around 1500 meters )

SIL workshop takes almost half of the SIL building and also considered as the biggest and most important department which provides both the area and tools (or machinery) that may be required for the manufacture or repair of manufactured goods. Our workshops are the places of production of SIL local products.

Planning and timing is our main concern, with a proper and good planning, the production can be much more effective.
