Another overhaul completed on this Blackmer LB942B LPG rail unloading compressor. This unit had suffered a catastrophic failure due to liquid slugging. One of the pistons was pushed into the cylinder wall and also damaged the packing box. We replaced the cylinder, piston and packing box, all of the worn internals and reassembled to Blackmer’s tolerances. The unit underwent a 4-hour run test, an orifice test and a leak test before final signoff. A fresh coat of Blackmer blue paint and she is ready to ship back to our client for installation with the piece of mind that comes with our 18-month workmanship warranty. After nearly 8 years of compressor rebuilds, we have not had a single warranty claim!
