BLACKMER LPG LB Compressor Series RECIPROCATING GAS COMPRESSORS
Oil-Free Gas BLACKMER Compressors for Liquid Transfer and Vapor Recovery
Blackmer oil-free gas compressors deliver high efficiency in handling LPG (propane and butane) and anhydrous ammonia. The LB Series of BLACKMER Reciprocating Gas Compressors are ideal for railcar, storage, and truck vessel unloading in addition to associated vapor recovery applications. The single-stage reciprocating gas compressors are designed to give maximum performance and reliability under the most severe service conditions. All BLACKMER LB Compressors are equipped with a ductile iron head and cylinder providing greater resistance to both thermal and mechanical shock. Additionally, the entire interior of the crankcase is coated, with a specially formulated epoxy coating, providing an added layer of protection for the compressor Equipped with high-efficiency valves, heavy-duty pistons, self adjusting piston rod seals and other robust features, the BLACKMER LB Series Compressors are designed for quiet efficient operation and ease of maintenance, with all components readily accessible for simple, quick, and easy replacement. Models are available with liquid transfer delivery rates up 2,575 L/min and piston displacement capacities from 11.9 to 212 m³/h with working pressure up to 24.13 bar.
SUPERIOR MATERIALS OF CONSTRUCTION With a special epoxy coating that protects the entire interior of the crankcase, and with numerous durable and robust components like high-efficiency valves, heavy-duty pistons, self-adjusting piston rod seals, wear-resistant crosshead assemblies, among others, the BLACKMER LB Series Gas Compressors are built to last in the harshest conditions. SUPERIOR DESIGN Designed so that components are readily accessible, BLACKMER LB Compressors make routine maintenance and replacement of wear parts simple, quick and easy.
BLACKMER LB Compressor Series | Standard Features
Special Epoxy Coating
The entire interior of the crankcase is coated with a specially formulated epoxy coating, providing an added layer of protection.
BLACKMER Ductile Iron Cylinder and Head
Ductile iron is stronger, much more resistant to thermal shock, and more corrosion resistant than ordinary cast iron.
BLACKMER O-Ring Seals Between the Cylinder and Head
O-rings in place of flat gaskets eliminate leakage and maintenance problems.
BLACKMER High Efficiency Valves
Designed to move more gas volume, Blackmer high efficiency steel valves are built for toughness and simplicity.
Constructed of corrosion resistant stainless steel discs and springs, the valves are easily removed for service without disturbing the piping. With their simple design they are easily repaired and reassembled.
BLACKMER One Piece Piston with Single Positive Locking Nut
The one-piece heavy-duty piston and single positive locking nut are both stronger and simpler than multi-piece designs with numerous fasteners found on competitor’s equipment. The LB940 Series features a two-piece piston design.
BLACKMER Pressure Assisted PTFE Piston Rings for Positive Sealing
A special chamber ensures pressure behind the ring to provide maximum sealing efficiency with minimal friction wear.
No Packing Adjustment Nut
The Blackmer spring loaded packing never requires adjustment. No expensive scored rods due to over tightened packing.
Wear Resistant Crosshead Assemblies
Pressure Lubricated Crankcase
Oversized Main Bearings
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.
An oil pump directly driven by the crankshaft ensures positive lubrication of all bearing surfaces. The oil pump is
self-reversing for either direction of rotation and is available with an external automotive type oil filter for extra protection.
LB Compressors | Compressor Selections
To select a compressor that best fits your application requirements, use the charts shown. The data provided is based on approximate delivery rates when handling LPG or anhydrous ammonia. Actual capacities will depend upon line restrictions, size and length of piping. Horsepower requirements for both liquid transfer and vapor recovery applications are based on moderate climatic conditions.
1* One single-acting cylinder
2* Two single-acting cylinders
3* Two double-acting cylinders
4* Compression Ratio defined as absolute discharge pressure divided by absolute inlet pressure.
5* Compression Ratios are limited by discharge temperature. High compression ratios can create excessive heat, i.e., over 177°C.
The duty cycle must provide for adequate cooling time between periods of operation to prevent excessive operating temperature.
