Reciprocating Gas Compressors
Blackmer HD Series
Oil-Free BLACKMER Gas Compressors for Industrial Gas Applications
Blackmer process compressors provide efficient and quiet delivery of oil-free industrial gas or air. These heavy-duty single and two-stage compressors combine advanced design technology and heavy-duty materials to give maximum performance with minimum maintenance.
BLACKMER HD Reciprocating Gas Compressors come in many different configurations and options, with multiple models available enabling choices between single or two-stage models, air-or liquid-cooled models, and single-, double- or triple-seal models.
Single-Stage & Two-Stage Models
Single-stage models are available in multiple sizes with piston displacements up to 212 m3/hr and working pressures to 1,000 psia 69 bar for use on low to moderate compression ratio applications. Two-stage models are also available for higher compression ratio requirements.
Air-Cooled & Liquid-Cooled Models
The air-cooled models (BLACKMER HD) are suitable for most applications, especially for operation at lower compression ratios and for liquefied gas transfer applications. While liquid- cooled (BLACKMER HDL) models cool the head and cylinder for more demanding applications.
Single-, Double- & Triple-Seal
Double-seal models are constructed with a single distance piece between two sets of piston rod seals. The distance piece provides leakage control and prevents oil contamination of the compressed gas stream. Triple-seal models use two distance pieces for maximum leakage control and are well suited for handling toxic, hazardous or corrosive gases. Ports are provided in each distance piece chamber for purging, pressurizing or venting.
SUPERIOR COMPONENTS
Compared to competitive compressors, all BLACKMER HD Series Gas Compressors are equipped with superior components, that are better constructed, for longevity in even the most severe operating conditions. The BLACKMER HD Series Gas Compressors stand apart from the competition and operate longer between maintenance cycles due to the following:
- Piston Rings: Twice as thick as competitor models
- Crankshaft & Needle Bearings: Designed to last a lifetime
- High-Efficiency PEEK Valves: Move more gas
- Special Epoxy Coating: Protects the interior of the crankcase
- S3R Oil Control Seal: Prevents oil migration for a true oil-free compressor
- One-Piece Piston: Stronger and simpler than multi-piece designs
- No Yellow Metals: The unit can withstand the corrosiveness of gases
Additionally, the BLACKMER HD Series Gas Compressors come equipped with an array of features such as a ductile iron head and cylinders, steel pistons and self-adjusting piston rod seals. BLACKMER HD Gas Compressors provide maximum performance, energy efficiency, quiet operation, low maintenance cost and reliability under the most severe service conditions.
HD Compressor Series | Standard Features
Ductile Iron Cylinder and Head
Ductile iron is stronger, much more resistant to thermal shock, and more corrosion resistant than ordinary cast iron.
Water-Cooled Cylinder and Head
Water-cooled cylinders and head on HDL models reduce operating temperatures and extend wear life.
High Efficiency Valves
Standard high efficiency PEEK valve plates provide extended life due to the low mass and self-lubricating qualities of the PEEK material. In addition, the slight ‘give’ of a plastic versus a metal plate allows it to survive more abuse and provide better sealing throughout the life of the valve. Optional stainless steel valves are also available. Note: BLACKMER HD080, BLACKMER HD160 and BLACKMER HD170 Series have TNT-12 impregnated steel valves plates and bumpers.
Extra Thick PTFE Piston Rings for Positive Sealing
Extra thick PTFE piston rings are double the size of rings in competitive compressors and provide more wear surface to provide greater ring life.
O-Ring Seals Between the Cylinder and Head
Buna-N O-ring head seals come standard and provide positive sealing under all operating conditions. Other material options include, PTFE, FKM, neoprene, and ethylene-propylene.
Precise Leakage Control
Triple-Seal (double distance piece), Double-Seal (single distance piece) and Single-Seal (no distance piece) models allow precise leakage control and minimize product contamination.
No Head Bolt Gasket
The center head bolts do not pass through the gas chambers and thus do not require a head bolt gasket. No gasket means no leakage source.
One Piece Piston with Single Positive Locking Nut
The one-piece piston is attached to the piston rod via one positive locking nut, making both stronger and simpler than multi-piece designs with numerous fasteners found on competitor’s equipment.
ANSI Connections
ANSI flanged connections allow maximum piping flexibility and are available on most HD Series Compressors.
Steel for Extra Life
Steel wrist pins ride on steel needle bearings for extra life under severe conditions.PTFE Piston Rod Seals
Self-adjusting PTFE piston rod seals provide maximum sealing and minimum friction.
Wear Resistant Crosshead Assemblies
The ductile iron crossheads feature special machined lubrication channels and ports to provide extensive lubrication of the crosshead and guide. Wear is minimized and galling is eliminated.
Pressure Lubricated Crankcase
Crankcase is pressure lubricated via a self reversing oil pump directly driven by the crankshaft. Oil is fed to all bearing surfaces, including the crosshead. An automotive type spin-on oil filter is standard.
Special Epoxy Coating
The entire interior of the crankcase is coated with a specially formulated epoxy coating, providing an added layer of protection.
No Yellow Metal
No brass or copper is present in the compressor keeping the compressor safe from the corrosive nature of some gases.

BLACKMER HD Compressors | Specifications – Single-Stage Models
Compression ratios are normally limited by discharge temperature. High compression ratios and certain gases can cause excessive heat, i.e. over 350°F (177°C). The duty cycle must provide for adequate cooling time between periods of operation to prevent excessive operating temperature.
BLACKMER HD Compressors | Specifications – Two-Stage Models
Compression ratios are normally limited by discharge temperature. High compression ratios and certain gases can cause excessive heat, i.e. over 350°F (177°C). The duty cycle must provide for adequate cooling time between periods of operation to prevent excessive operating temperature.
