Reciprocating Compressors


High-speed reciprocating compressor model FS604 has two 14.5"

cylinders, one 9.50" cylinder and one 6.25" cylinder – all with

Variable Volume Clearance Pockets (VVCPs). This configuration is

most often used for gas gathering applications where it provides

superior flexibility with options for changing the number of stages

and liner bores.

Exemplary Engineering


Cooper Machinery Services employs experienced engineers who use the latest tools and techniques to work out solutions for complex problems and bring new ideas to market. Application engineering – teams of engineers develop custom solutions for specific applications, finding just the right combination of equipment and technology to meet stringent demands, including fully packaged compressors. Rapid prototyping and virtual testing – using sophisticated 3D modeling software, advanced simulation software and 3D printing techniques, our engineers can perform thermal, stress, combustion and emissions analysis on parts and assemblies before a single prototype is built. In the constant pursuit of improvement, we explore new technologies, test new designs and experiment with new ideas.



Technology Leadership


Our HSR products range from 60 HP (45 kW) to 9000 HP (6714 kW), with a variety of piston rod load capacities and frame stroke

combinations. Over 15,000 of our compressors can be found around the globe, working in fuel gas boosting, gas lift, CNG fueling,

reinjection, gas gathering and vapor recovery applications – operating 24-hours a day, seven days a week.




Cooper Machinery Services compressors are integrated into a package by a global network of authorized packagers. The compressor is

matched with a driver, coolers, controls, and piping typically on a single skid. This allows the complete compressor package to

be easily moved to a new location. This concept lowers your installation, site construction, and re-application costs.

Our compressors are designed to be directly connected to a variety of reciprocating natural gas engines (720 to 1,800 rpm) and

electric motors (750 to 1,800 rpm). A variety of compressor frame strokes allow the compressor to be perfectly matched to the

optimum driver.




It is the nature of natural gas production that pressures and flows often change. Therefore, greater productivity can be attained

if the compressor is easily adaptable to the new operating conditions. Many Cooper Machinery Services high-speed reciprocating compressors feature field-replaceable cylinder liners that allow the cylinder bore to be increased or decreased as operating conditions change. When the cylinder must be changed, several cylinders have identical flange connections, allowing the same piping and bottles to be used. In either case, there is no need to modify the on-skid piping and accessories, further lowering modification costs. If the cylinder bore is ever damaged, it is less expensive and

less time consuming to replace a liner than a complete cylinder. A variety of capacity-control devices are also available, including our standard variable-volume clearance pockets, featuring generous clearance volumes. These provide greater flexibility for changing operating conditions.

The modular design of our high-speed reciprocating compressors allows frames and cylinders to be easily reconfigured, offering

increased flexibility with a lower cost.




Cooper Machinery Services API 11P high-speed reciprocating compressors are balanced opposed to minimize vibration by equalizing the opposing reciprocating forces on the crankshaft. Heavy, ribbed frames distribute reciprocating stresses evenly for greater strength and longer life. Many compressor cylinders are water jacketed to lower operating temperatures, provide thermal stability, and improve valve life.
