Jabsco 1" Electro-Magnetic Clutch Pump – 12V – 11860-0005

The Jabsco 11860-0005 Electro-Magnetic Clutch Pump is a heavy-duty engine-driven raw water pump designed for marine air conditioning, refrigeration, and engine cooling support systems. Featuring a 12V electro-magnetic clutch, this pump engages only when power is applied, reducing wear, heat buildup, and parasitic engine load when cooling is not required.

Built with a corrosion-resistant bronze housing and Jabsco’s proven flexible impeller design, the pump delivers reliable seawater flow and excellent self-priming capability. The 1-inch inlet and outlet ports provide efficient water movement for high-demand marine applications. Trusted by OEMs and marine professionals, this clutch pump offers long service life in both freshwater and saltwater environments.

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.

Mounting Bracket: A custom or universal bracket to secure the pump to your engine block.
Electrical Switch & Wiring: A 12V DC dash switch and appropriate gauge wire to activate the clutch.

Essential Spares

It is a standard marine best practice to carry a backup for wear-and-tear parts. The Jabsco 920-0003P Nitrile Impeller Kit includes a replacement impeller and the necessary gasket for the end cover.

Would you like me to find the Jabsco 920-0003P Impeller Kit so you can have a spare ready, or perhaps the Vacuum Switch used to protect the pump from running dry?

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.
