CAT349 CAT352 Hydraulic Main Pump 566-8632 5668632 569-8251 5698251 349GC 345GC Piston Pump

Verschiebung:

Rated: ~280 cm³/rev (17.09 in³/rev) (optimized for high flow at operating speeds).

Durchflussrate:

Maximum: 770–780 L/min (203–206 GPM) at 2,000 Drehzahl (matches 349/352’s hydraulic circuit demands).

345GC Variant: Slightly reduced to ~750 L/min (198 GPM) for balanced efficiency.

Pressure Ratings:

Maximum Operating Pressure: 350 Bar (5,076 psi) (main implement circuit).

Peak Pressure: 420 Bar (6,091 psi) (short-term for heavy-duty operations like travel or lifting).

Speed:

Maximum Input Speed: 2,000–2,300 RPM (synchronized with excavator engine speed).

Torque:

Maximum Input Torque: ~2,800–3,200 N·m (handles high-pressure loads without performance loss)
