Meziere WP200S Electric Water Pump 200 Series Big Block Chevy with Expansion Tank

The Meziere WP200S is a 200 Series electric water pump with integrated expansion tank designed specifically for Big Block Chevy engines. This high-performance pump delivers 35 gallons per minute of flow, making it ideal for normally aspirated engines up to 650 horsepower. The innovative reservoir design eliminates the challenges of filling difficult cooling systems, particularly in dragsters with horizontal or low-mounted radiators.

Key Features:

• CNC-machined from 6061-T6 billet aluminum with black anodized finish for superior corrosion resistance and lightweight construction
• Built-in expansion tank serves as fill point and air separator, eliminating air locking and cavitation issues
• Stainless steel large diameter main shaft with high-performance carbon-ceramic seal for lasting reliability
• Flows 35+ gallons per minute at 12 volts with 6-7 amp draw under normal operation
• Weighs only 8.2 lbs complete, significantly lighter than mechanical pumps
• Epoxy-coated motor with radio frequency suppression circuit to reduce ignition interference
• 1-inch NPT female inlet accepts various adapter fittings for radiator hose compatibility
• Clears most cam belt drives and blower drive systems

What's Included: Complete kit includes pump assembly with expansion tank, gaskets, mounting hardware, and wiring. Inlet fitting sold separately based on radiator hose size requirements.

The WP200S is specifically engineered for dragsters where the radiator is positioned flat or horizontally, but also works excellent for kit cars and other applications where traditional radiator access is limited. The pressure cap location on the low-pressure side allows easy system filling while the pump runs, maintaining proper coolant levels automatically. Backed by Meziere's quality American manufacturing and proven reliability in racing applications.
