Compressor Repair

Bender CCP will rebuild your used compressor cylinders back to original sizes. We can rebuild used cylinder bores at a fraction of the cost of replacement cylinders. With our large machining capacity we can easily manufacture replacement cylinder liners to meet project specifications. Our staff has over fifty years of experience reworking Reciprocating compressor cylinders and has the largest capacity on the west coast. We have experience with cylinders ranging in size from 2” – 40”. Bender CCP uses high quality spun cast iron that meets or exceeds OEM requirements. All cylinders are power honed to finish size and to produce the desired surface finish.

Delivery of refurbished equipment can be accomplished quickly due to the size of the facility and the fact that we work two shifts. In turnaround situations our crews work around the clock to meet project schedules.

Bender CCP typically encourages customers to provide the head during a liner replacement to ensure proper fit and to ensure that the head once installed has the rod bore concentric with the liner bore. The head may require skim cutting to make faces flat and perpendicular to the bores. Bender CCP can also replace studs, tap valve holes, repaint the cylinder, and repair damaged surfaces. It is our intent to catch any potential issues up front and to return your equipment in the desired state the first time.

A cylinder relining may also be required to due to changes in field operations. Bender CCP can easily reverse engineer a liner or manufacture a replacement liner to accommodate a different size piston.

It is common to manufacture a rough turned liner to put into warehouse stock to reduce turnaround time during a shutdown. Bender CCP will manufacture a liners and endcaps (for later finish turning) to accommodate such requests.
