Clearance Pockets

Custom-designed or reconditioned to fit your operating conditions.

Most high-speed units run unattended and operating conditions continually change. With CECO Automatic Machined Clearance Pockets the units can be kept closer to 100% load. These pneumatically-actuated valve cap unloaders allow you to change load and capacity with varying operating conditions while maintaining high compressor efficiency. Custom-designed and exactly tailored to your size requirements, our machined pockets can be fitted with pneumatic actuators to open and close with a low-pressure air or gas signal and comply with API 618.

For shorter delivery and exact volume, the pockets are made from machined parts–not castings. They are tested to 1.5 times the maximum working pressure. We can assist you in determining the optimum cubic-inch-size pocket required to satisfy your operating conditions.
