TMC Automatic Bilge Pump 1500 GPH, 24V — a smart, hands-off solution from the Auto-Eye Tech Series that keeps your vessel dry with minimal fuss. Engineered for reliability in demanding marine environments, this 24VDC submersible pump delivers steady bilge performance when you need it most, without the need for a float switch.

Why this bilge pump stands out

• Fully automatic operation with built-in reed sensor: the pump starts the moment water rises to 60 mm and runs only as long as moisture remains, conserving power and reducing wear.
• No float switch required: fewer moving parts mean fewer failure points, ensuring dependable activation even in rough sea states or dirty bilges.
• : rust- and corrosion-protected stainless steel shaft paired with a compact, long-life motor and high-impact, durable plastic housing withstands marine conditions.
• Strong pumping capability: 1500 gallons per hour (5676 LPH) capacity to rapidly remove water, helping you regain dry safety on board.
• Compact, flexible installation: 24VDC operation with a 1" (26.5 mm) hose connection and a delivery head of 13 ft (2.5 m) fits a wide range of bilge spaces.
• : draws about 4.5A at 24V with a 6A fuse, balancing performance with power availability on boats and RVs.

How it works in real-world use

In everyday marine scenarios, water entering the bilge is detected by the built-in Auto-Eye liquid level sensor. When the water hits 60 mm, the pump automatically powers up, discharges through the 1" hose, and continues until the bilge level drops below the trigger point. Because there’s no float switch, you get fewer mechanical failures and a more reliable response, even in cluttered bilges or when fouled with debris.

Ideal applications

• Small to mid-sized boats and sailboats that need dependable bilge management without extra wiring for float switches.
• RVs, campers, or utility boats where simple, automated water removal reduces manual maintenance.
• Vessels where space is at a premium—the compact motor and slim profile simplify installation in tight bilge compartments.
• People seeking a durable, long-lasting pumping solution with minimal ongoing adjustments or replacements.

What makes it a smarter choice

Compared to traditional bilge setups, the TMC Auto-Eye Bilge Pump removes the complexity of float switches while delivering rapid transfer of bilge water. The combination of a rugged stainless steel shaft, a protected housing, and a high-output motor results in a pump that performs when you need it and withstands the harsh marine environment over time.

Installation and maintenance tips

• Plan for a secure mounting location in the bilge with easy access for hose connections and routine inspection.
• Ensure the 24V power source is stable and fused at 6A for safe operation.
• Check the hose for clogs or kinks and confirm the outlet is clear to maintain the 13 ft head.
• Periodically inspect the stainless shaft and housing for signs of wear or corrosion, and rinse to remove salt buildup after saltwater use.
