Hydraulic A-Pad Pump

Hydraulic A-Pad Pump

This is an auxiliary hydraulic gear pump, commonly known as a charge pump, used on rear discharge concrete mixers. It features a counter-clockwise rotation and mounts to the 'A-pad' port on the main hydrostatic pump. Specifically for London mixers, this pump provides the necessary hydraulic flow and pressure to operate the chute hoist cylinder. It serves as a direct replacement for worn or failed auxiliary pumps, restoring the functionality of critical hydraulic systems like the chute lift.

Key Features

• Counter-clockwise (CCW) / Left Hand (LH) rotation.
• Standard SAE A-Pad mounting flange for easy installation on main hydrostatic pumps.
• Powers auxiliary functions, most commonly the chute hoist cylinder on London mixers.
• Direct cross-reference for multiple OEM and aftermarket part numbers.
• Durable cast iron construction for long service life in demanding mixer applications.
