Wide range applications in nitrogen boosting, CNG refueling station, HP air compressor sets etc.
Integral frame design, the crankcase with reinforced ribs and crosshead guide;
High precise, balanced design minimizes vibration, crankshaft fatigue, bearing bush load, increasing service life as a result;
Frame: One-piece, cast iron heavily ribbed casting with integral crosshead guide and tie-bolt construction. Aluminum top cover and end covers;
Crankshaft: Total ductile iron, Babbitt surface;
Bearing: precise, split tri-metal main and connecting rod bearings, steel backed and bearing cap are held in place by 2-bolt or 4-bolt;
Connecting rod: Forged steel, accurate machined and balance weight, H-section, the oil passage in rifle drilled hole for pin lubrication, using 4140 steel bolt;
Crankshaft: Heat-treated forged steel, SAE5046 or SAE4140 steel. Balanced weight ensures a long stable service life. Distance of centerline to bottom of frame is 14.2 in. (36.0cm); Main bearing diameter is 4.9in. (124mm);
Maximum speed, 1500 rpm, Maximum discharge pressure, 14Mpa;
Wide range applications in natural gas disposal, fuel gas boosting, gas injection, gas storage, gas lifting, etc.
