Wide range applications in nitrogen boosting, CNG refueling station, HP air compressor sets etc.

   High precise couple-free, balanced design minimizes vibration, crankshaft fatigue, bearing bush load, increasing service life as a result;

Frame: One piece, cast iron heavily ribbed casting with tie-bolt construction Aluminum top cover and end covers;

Crosshead: one piece ductile iron, Babbitt surface;

Bearing: Accurate, split tri-metal, main and connecting rod bearings, steel backed and connecting rod caps are held in place by 2-bolt or 4-bolt;

Connecting rod: 4140 steel, precise machined and balance weight, the oil passage in rifle drilled hole for pin lubrication;

Crankshaft: Forged or heat-treated SAE4140 steel with nitride treatment. Balanced weight ensures a long stable operation service life. Distance from centerline to bottom of frame is 10.25 in. (26cm);

Maximum speed 1800 rpm, Maximum discharge pressure, 37Mpa;
