THM – A2FO – Rotary group and spares
Completely restore the immense high-pressure capabilities of your open-circuit hydraulic drives with the THM A2FO Series Rotary Groups and Spares. Engineered specifically for fixed displacement, bent axis axial piston pumps, these precision rebuild kits are the ultimate cost-saving solution for heavy fleet maintenance. Instead of replacing a massive, expensive cast-iron pump housing, your technicians can drop in these exact-tolerance internal rotating components to instantly eradicate fluid bypass and performance lag. Covering a comprehensive range of displacements from the nimble Size 16 to the colossal Size 160, the A2FO spares guarantee your heavy mobile equipment, industrial presses, and commercial marine drives return to absolute peak volumetric efficiency.
Core Technical Specifications
- Component Architecture: Fixed Displacement Bent Axis Piston Pump Rotary Group
- Pump Compatibility: A2FO Series Open-Circuit Hydraulics
- Available Displacement Sizes: 16, 28, 56, 80, 107, 125, and 160
- Supported Models: A2FO16, A2FO28, A2FO56, A2FO80, A2FO107, A2FO125, A2FO160
- Available Spare Components: Bent axis cylinder blocks, tapered pistons with sealing rings, valve plates, center pins, and heavy-duty drive shafts.
Key Features & Engineering Advantages:-
- Total Volumetric Restoration: The robust A2FO bent axis design is engineered for extreme pressures. Replacing a worn, scored rotary group instantly restores the unit's ability to translate mechanical shaft power into massive, high-pressure fluid flow without internal leakage.
- Exact OEM Drop-In Tolerances: Every tapered piston, cylinder block, and valve plate is micro-finished to guarantee flawless compatibility. This ensures rapid run-in times and a perfect, high-pressure seal within your existing A2FO pump castings.
- Massive Cost & Time Savings: Protect your capital budget and slash machine downtime. Rebuilding the internal "engine" of the pump directly on the workbench bypasses the long lead times and high freight costs associated with ordering a complete replacement assembly.
- High-Cycle Industrial Durability: Forged from premium, hardened metal alloys specifically treated to withstand continuous shock loads, abrasive fluid contamination, and the brutal pressure hammering inherent in heavy industrial environments.
- Complete System Rejuvenation: Replacing the entire rotary group as a matched set guarantees even wear and synchronized performance, extending the lifespan of the rebuilt pump far beyond that of piecemeal repairs.
Ideal Industry Applications
The rugged, high-pressure capabilities of A2FO bent axis pumps make these rotary spares essential for:
- Heavy Mobile Hydraulics: Restoring the primary open-circuit power on modern concrete pump trucks, heavy road milling machines, and massive articulated dump trucks.
- Industrial Manufacturing: Servicing the fixed-displacement pumps driving heavy metal-forming presses, heavy-duty shearers, and high-capacity extrusion machinery.
- Marine & Offshore: Rebuilding the primary hydraulic drives powering heavy anchor winches, deck cranes, and specialized offshore drilling equipment.
- Heavy Material Handling: Maintaining the robust lifting and driving circuits on large-scale industrial straddle carriers and high-tonnage port cranes.
Why Choose THM A2FO Rotary Spares?
- Uncompromising High-Pressure Flow: Fresh tapered pistons and perfectly matched cylinder blocks guarantee your pump delivers maximum fluid power under heavy, continuous loads.
- Sustainable Fleet Maintenance: Rebuild your heavy iron castings for a fraction of the cost of new units, drastically lowering your overall maintenance budget and reducing waste.
- Comprehensive Model Coverage: From the compact A2FO16 to the colossal A2FO160, we supply the exact internal components your heavy machinery demands.
