GPD 6512789 HD SD7H15 A/C Compressor 10-Groove Serpentine Clutch 12V

The GPD 6512789 is a heavy-duty SD7H15-style A/C compressor designed for mobile and commercial HVAC applications. Built to Sanden SD7H15 specifications, this unit features a 10-groove serpentine clutch pulley and a 12-volt electromagnetic clutch coil, making it a direct-fit replacement in high-demand serpentine belt drive systems.

Key Features:

• Compressor Type: SD7H15 heavy-duty 7-piston design for superior displacement and cooling capacity
• Clutch Configuration: 10-groove serpentine pulley for maximum belt contact and torque transfer in high-load drive systems
• Voltage: 12V electromagnetic clutch coil
• Displacement: Approximately 155cc (9.5 cubic inches) per revolution
• Refrigerant Compatibility: Compatible with R134a refrigerant systems
• Construction: Heavy-duty internal components engineered for continuous-duty operation and extended service life
• OEM-Style Fit: Manufactured to meet or exceed original equipment specifications for fit, form, and function

The SD7H15 platform is one of the most widely used compressor designs in commercial trucking, heavy equipment, and specialty vehicle HVAC systems. The 10-groove pulley configuration is specifically suited to high belt-load environments where additional groove count provides improved belt grip and reduces the risk of belt slippage under peak compressor load.

Installation Note: Always flush the A/C system and replace the expansion valve or orifice tube and receiver-drier/accumulator when installing a new compressor to prevent contamination from damaging the new unit.
