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.
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.
Performance Specifications (Matching Original Pump)
Fit For: Danfoss 45 Series FRR090C Piston Pumps
Displacement: 90cc/rev
Pressure Rating: Nominal 260bar, Peak 350bar
Max. Speed: 3600rpm
Material Standard: Identical to OEM alloys, steel, and rubber per Danfoss specifications
Precision: Micron-level machining, matching original clearances
Key Advantages
OEM Quality & Perfect Fit: 1:1 replication of OEM dimensions, materials, and processes for zero installation deviation and full performance retention.
Durable & Heavy-Duty: Hardened/wear-resistant core parts withstand shock, vibration, dust, and harsh operating conditions.
High Efficiency & Low Noise: Optimized mating surfaces and flow paths deliver ≥94% volumetric efficiency, low noise, and reduced energy consumption.
