Danfoss FRR090C Components are original high-precision repair kits engineered for the Danfoss 45 Series FRR090C open-circuit axial variable piston pump. Covering all core wear parts of the pump housing, they fully match the original pump’s pressure, flow, and control characteristics, ensuring the hydraulic system regains factory performance after repair. Ideal for overhaul and maintenance of pumps in heavy-duty equipment such as construction machinery, agricultural machinery, and material handling equipment.

Core Component Kit

• Cylinder Block (Rotor): High-rigidity alloy steel with precision machining of inner bores and valve plate mating surfaces, ensuring smooth piston reciprocation, wear resistance, and impact resistance.
• Pistons & Shoes: Set of 9 high-precision piston assemblies with special surface hardening. Stable displacement via swashplate interaction, low friction, long service life.
• Valve Plate: Bimetallic composite structure optimizes oil flow, improves volumetric efficiency, and reduces operating noise.
• Retainer Plate & Springs: Robust return mechanism ensures consistent piston-shoe contact with swashplate for stable suction/delivery.
• Bearings & Seals: Tapered roller bearings for high load capacity; Viton lip seals for oil resistance, high temperature resistance, and leak prevention.
• Control Spools/Valve Plates: Compatible with Load Sensing (LS) and Pressure Compensator (PC) controls for precise swashplate angle and flow regulation.
