*Number of cylinders. Up to 12 cylinders in a single crankcase.
Booster primary
Single-piece, cast iron crankcase with tight-tolerance
transverse spacers fitted above the bearing housings
between the two sides of the frame. Extremely stiff,
closed body with large openings that cut maintenance
time and cost.
Hypercompressor
Special crossheads design
Sliding surfaces pass through plunger axis for perfect
straight plunger action in both cold and hot conditions.
No on-site realignment required.
Steel crossheads equipped with amply sized
shoes that are completely machine finished and
interchangeable, eliminating the need for any manual
adjustment or shimming.
Easy accessibility & maintenance
Frame and cylinder tie rods tighten with hydraulic
jacks. Preassembled cylinder components enable
simple and quick maintenance and replacement.
Proprietary bi-metallic (aluminum and tin) main and
big-end bearings. Main bearings are vertically split to
eliminate surface discontinuities from the most heavily
loaded area, thereby increasing the load capability and
reliability.
Optimized packing design
Second stage cylinders have an average
operating life of 20,000 hours and frequently
achieve well over 32,000 hours without
replacement.
All main threaded connections (piston to piston rod,
piston rod to crosshead, connecting rod to big-end tie
rods, frame crosspieces, anchor bolts, high-pressure
cylinder bolting) are hydraulically tightened.
High-performance cylinders
Maximum reliability through shrink-fit packing cups,
extensive use of auto frettage, silver plating and shot
peening. Plunger is made of solid tungsten carbide
with a cobalt binder or tungsten carbide-coated steel.
