Key Performance Features

• Engine-Driven Power: This pump is designed to be belt-driven by your gasoline or diesel engine using two A-size belts. The 12V DC electromagnetic clutch allows you to engage or disengage the pump remotely via a dash switch or float switch.

• High-Volume Flow: Delivers a nominal flow of 23 GPM (87 LPM) at 1,750 RPM. At maximum engine speeds (up to 3,000 RPM), it can reach capacities of nearly 35 GPM.

• Reliable Self-Priming: Effectively self-primes from a dry start up to 7.8 feet (2.4m). Once the impeller is wet, it can maintain a vertical lift of up to 22 feet.

• Manual Override: A unique safety feature of the 11860-0005 is the inclusion of mechanical engagement screws. If your electrical system fails, you can manually lock the clutch to keep the pump operational.

• Debris & Abrasive Tolerance: The flexible Nitrile impeller handles hard and soft solids without clogging and can withstand abrasive wear, making it suitable for messy bilge or industrial drainage tasks.

Summary for the User

The Jabsco 1" Electro-Magnetic Clutch Pump - 12V - 11860-0005 is an ideal "fit-and-forget" solution for emergency bilge pumping, high-pressure washdowns, or engine cooling. By harnessing the engine's mechanical power, it ensures you have high-capacity pumping even if your batteries are low. It is widely regarded as one of the most rugged and versatile general-purpose pumps in the Jabsco catalog.

Pro Tip: To prevent accidental damage, consider installing the Jabsco 4732-0000 Vacuum Switch. This will automatically disengage the clutch if the pump runs dry for more than 30 seconds, protecting your impeller from heat damage.
