Convert-A-Ball OP712 12V Self-Priming Oil Change Pump with Reversible Flow

The Convert-A-Ball OP712 is a self-priming impeller pump designed for efficient diesel and oil transfer applications. This versatile 12-volt pump is ideal for completing oil changes on generators, boat engines, and other marine equipment without the mess of traditional methods.

Key Features:

• Self-priming impeller design for reliable fluid transfer
• Reversible flow direction controlled by integrated switch
• 12-volt DC operation with battery clamp connections
• 8 amp draw with maximum working pressure of 15 PSI (1 bar)
• Designed for discontinuous use applications
• Handles organic contaminants commonly found in fuel and oil tanks

This pump simplifies routine maintenance on marine engines and generators by extracting used oil and transferring new oil efficiently. The reversible flow feature allows the same pump to both extract and refill, making oil changes faster and cleaner. For applications with larger particles such as sand or metal shavings, an in-line stainless steel strainer is recommended before the pump inlet.
