Parker Denison M6F Gold Cup Series

SKU: Parker Denison M6F Gold Cup Series

The Parker Denison M6F (Gold Cup Series) is a heavy-duty fixed displacement axial piston motor/pump designed for the most rigorous open and closed-loop circuit applications. Renowned for its robust “Gold Cup” barrel bearing design, the M6F series ensures reliable operation at high pressures (up to 5000 psi continuous) and high speeds. The specific model M6F3N1D3 features a standard SAE mount and spline shaft, making it a direct replacement for demanding industrial and mobile machinery.

Key Features:

Series: Gold Cup (Size 6)
Model: M6F (Fixed Displacement)
Displacement: 98.3 cm³/rev (6.00 in³/rev)
Max. Pressure: 350 bar (Continuous) / 420 bar (Peak)
Design: Axial piston, heavy-duty barrel bearing.

Product Overview The Parker Gold Cup M6F Series represents the pinnacle of hydraulic transmission technology. Originally developed by Denison Hydraulics, this series features a unique barrel bearing design that runs on a film of oil, eliminating the metal-to-metal contact typical in other designs. This results in exceptional durability, reduced wear, and the ability to withstand high shock loads and vibration.

The M6F3N1D3 unit is widely used in hydrostatic transmissions where reliability is non-negotiable, such as in shredders, marine winches, drill rigs, and mining equipment.

Why Choose Parker Gold Cup M6F?

Unmatched Durability: The patented barrel bearing design allows the pump/motor to operate at higher pressures and speeds for longer periods than competitive units.
High Efficiency: Low internal leakage and high volumetric efficiency ensure maximum power transfer.
Fast Response: The low moment of inertia of the rotating group allows for rapid changes in speed and direction (when used in bi-directional circuits).
Versatile Fluid Compatibility: Capable of running on a wide range of fluids, including biodegradable and fire-resistant fluids.

Common Applications:

Marine: Winches, Steering gears, Thrusters.
Mining: Blast hole drills, Excavators.
Industrial: Shredders, Hydraulic presses, Test stands.
Oil & Gas: Top drives, Mud pumps.
