Product details
I. Product Overview
TheCBQ-F573-AFPis ahigh-pressure external gear pumpdesigned by professional hydraulic manufacturers for industrial equipment, construction machinery, and mobile machinery hydraulic systems. Key features include:
• High-pressure design: Rated pressure up to25 MPa, peak pressure28 MPa, suitable for high-load applications.
• Compact structure: Lightweight and space-saving, ideal for integration into constrained hydraulic systems.
• Low noise: Optimized gear meshing and housing design, operating noise ≤75 dB (at 1m distance).
• High reliability: Uses high-strength alloy steel gears and bearings, with a lifespan exceeding5,000 hours(under continuous operation).

II. Technical Specifications
【表格】
Parameter CBQ-F573-AFP Specifications
Displacement (cc/rev) 73
Rated Pressure (MPa) 25
Peak Pressure (MPa) 28
Speed Range (rpm) 600–3000
Weight (kg) 12
Port Size Inlet: G1/2; Outlet: G1/2
Fluid Viscosity Range 10–400 cSt (recommended 32–68 cSt)
Operating Temperature -20°C to +80°C (optional -40°C low-temp version)
Key Notes:
• Flow Calculation: Theoretical flow = Displacement × Speed ÷ 1000 (e.g., at 1800 rpm: 73 × 1800 ÷ 1000 = 131.4 L/min).
• Pressure Adaptation: Reserve 10%–20% pressure margin in system design to avoid prolonged operation near peak pressure.

III. Structure and Materials
1. Gear Pair:
• Material: High-chromium alloy steel (carburized and quenched, hardness HRC58-62).
• Tooth Profile: Modified involute gearing to reduce meshing impact and improve volumetric efficiency (≥90%).
2. Bearing System:
• Front Bearing: Double-row angular contact ball bearing for combined axial/radial load support.
• Rear Bearing: Cylindrical roller bearing for enhanced radial support.
3. Shaft Seal Design:
• Seal Type: Double-lip fluororubber oil seal, resistant to 120°C oil temperature, IP65 leakage protection.
• Auxiliary Seal: O-ring + backup ring combination to prevent high-pressure oil leakage into the bearing chamber.
4. Housing Material:
• Aluminum alloy die-cast housing (anodized surface treatment) for lightweight and corrosion resistance.
------
IV. Performance Advantages
1. High Efficiency:
• Volumetric efficiency ≥90%, mechanical efficiency ≥92%, total efficiency ≥83% (under rated conditions).
• Flow pulsation rate ≤5%, suitable for systems requiring stable flow (e.g., servo control).
2. Contamination Resistance:
• Optimized gear clearance design, tolerates NAS 6-grade (ISO 18/15) fluid cleanliness.
3. Adaptive Startup:
• Elastic deformation of gear pairs compensates for clearance during low-temperature startup, reducing wear.
4. Maintenance Convenience:
• Modular design allows rapid replacement of gear pairs and bearings, with repair time reduced to ≤30 minutes.

V. Typical Applications
1. Construction Machinery:
• Hydraulic supply for excavator slewing motors and crane luffing mechanisms.
• Case Study: A 20-ton excavator’s slewing system achieved a 15% reduction in startup time after adopting CBQ-F573-AFP.
2. Industrial Equipment:
• Hydraulic supply for injection molding machine ejection systems and die-casting machine clamping mechanisms.
• Case Study: A 680-ton injection molding machine’s clamping cylinder maintained stable 23 MPa outlet pressure for rapid clamping.
3. Agricultural Machinery:
• Hydraulic drive for combine harvester header lifting and forage harvester feed rollers.
• Case Study: A grain combine harvester’s header hydraulic system operated leak-free for 2,000 hours.
4. Marine Equipment:
• Hydraulic power units for deck machinery (anchors, winches).
• Case Study: A coastal fishing vessel’s anchor system operated corrosion-free for 12 months in salt-spray environments.
