Reciprocating Gas Compressors
Blackmer NG series
BLACKMER NG Compressors - Natural Gas Compressors
Specially designed for the oilfield, the BLACKMER NG Series Reciprocating Gas Compressors have proven themselves over and over as dependable and robust equipment for oil and natural gas production, vapor recovery and storage operations. These oil-free reciprocating gas compressors are constructed and equipped with superior components, which help provide maximum performance and reliability under the most severe service conditions. BLACKMER NG Series Reciprocating Gas Compressors are highly efficient, heavy duty single- and two-stage oil-free compressors. Each BLACKMER NG Series Compressor is constructed with a single distance piece between two sets of seals on each piston rod. The distance piece provides leakage control and prevents oil contamination of the compressed gas stream. Ports are provided in the distance piece chamber for purging, pressurizing or venting. This enables NG Series Compressors to be utilized in a wide range of wellhead applications for oil-and-gas production and storage operations. Additionally, NGS Series Sour Gas compressors can handle liquefied gases with up to 8% dry hydrogen sulfide (H2S) content

Blackmer NG Compressors | Standard Features
All Blackmer NG Compressor models feature an oil-free design and high efficiency valves that provide superior sealing characteristics, high efficiency and durability. This makes them ideal for use in the most severe oilfield and wellhead applications.
Other standard features include:
- A heavy-duty, precision-ground crankshaft for smooth, quiet operation with long-lasting bearings
- A specially formulated crankcase epoxy coating for added protection
- Self-adjusting loaded-glass PTFE piston-rod seals that maintain constant sealing pressure that helps prevent oil contamination and cylinder blow-by
- One-piece ductile-iron pistons connected to the piston rod with a single positive-locking nut for added strength and easier maintenance
- Self-reversing oil pump that lubricates the crankcase and all running gear components through positive oil distribution
- An S3R oil-control seal that keeps oil in the crankcase for enhanced leakage control
- High-efficiency, long-lasting valves with precision-engineered clearances and spring tension that allow the movement of more gas volume with each piston stroke
Specific features of the NG Series Compressors include:
- No use of yellow metals (brass and copper) for protection against corrosion
- Self-lubricating PTFE piston rings with a special pressure-assisted design for maximum efficiency with minimal friction wear
- Steel wrist-pin needle bearings for long life when used in high rod-load applications with wrist-pin lubrication assured under all load conditions
- Isolation chambers with single-distance pieces for leakage control, keeps crankcase lubricant isolated from the compression chamber
- Pressure-containing parts sealed with FKM or PTFE O-rings for positive sealing under all operating conditions
- Valves and valve plates constructed of self-lubricating PEEK material for superior sealing, high efficiency and extended service life; optional stainless-steel valves are also available
Wherever wellhead gases need to be cost-effectively extracted and efficiently managed, Blackmer NG Series Gas Compressors are on the job.
With decades of deep oil and gas industry experience, Blackmer earned its reputation for product innovation, quality, and most critical to Wellhead Operators – reliability – especially in rugged and remote unmanned locations. These professionals rely on Blackmer NG Gas Compressors to perform without fail at the wellhead and storage tank batteries for an array of critical applications.
Annulus Reduction
Blackmer NG Compressors reduce wellhead gas pressure improving oil flow into underground formations for more efficient oil production enhancement.
Vapor Control
The wellhead and tank batteries are the two major sources of fugitive methane emissions. Common air compressors lack critical seals to prevent gas leakage and crankcase oil dilution. Condensate can form in the compressor, which will contaminate crankcase oil. Condensate will break down the oil acting like a solvent, stripping bearings of critical lubrication. The result is damaging heat, friction, and equipment damage or breakdown. Blackmer NG Compressors are specially designed to capture and control wellhead gases. The design prevents gas leakage and oil contamination.
Vapor Recovery
Increasingly stringent state and federal clean air rules are promoting the reduction and elimination of gas venting and flaring of fugitive gas emissions. Blackmer NG Compressors are unsurpassed in reducing emissions and the recovery of saleable wellhead gas, thus protecting the environment, supporting regulatory compliance and improving the bottom line
Product Transfer
Blackmer NG Compressors move wellhead and tank battery vapors into low to medium pressure pipelines where it can be further processed downstream at a gas processing station. Wellhead operators attest to the importance of equipment reliability and uptime performance, and understand the risks and downtime costs of relying upon less capable, less durable air compressors. They avoid the unnecessary expense of daily and weekly oil changes, and the frequent replacement of these less durable compressors. They recognize the Blackmer product outlasts and outperforms, requiring only routine maintenance. Its ability to remain on 24/7/365 continuous duty for the long haul is testimony to Blackmer reliability and bottom line results.
