Jabsco 18930-0010 Bronze Bracket Mount Engine Cooling Pump
The Jabsco 18930-0010 is a bronze bracket mount engine cooling pump built to move raw water through an engine cooling circuit with dependable, self-priming performance. Its flexible neoprene impeller creates suction on its own, so the pump pulls water into the system from a dry start without the need for manual priming, which makes installation and startup considerably easier for engine builders, technicians, and equipment owners alike.
Constructed from solid bronze with a carbon and ceramic mechanical seal, this pump is designed to resist corrosion and hold up under continuous duty in demanding cooling applications. The bracket mount configuration allows for straightforward installation onto an engine or equipment frame, and the 1-1/4" ports are sized to accept standard ID hose for efficient water transfer at higher flow volumes.
While it is widely used to keep marine engines running cool, this same pump design works just as well in industrial engines, generator sets, and other equipment that relies on a liquid-cooled circuit. Anyone replacing a worn-out cooling pump or upgrading their engine's water circulation system will find the 18930-0010 to be a reliable, drop-in style solution built for long service life.

Frequently Asked Questions
Q: Can the Jabsco 18930-0010 be run dry during startup or testing?
A: No, this pump relies on the liquid being pumped for internal lubrication, so it should not be run dry for more than about 30 seconds or the impeller can be damaged.
Q: Is this pump suitable for non-marine engine applications?
A: Yes, while it is commonly used in marine engines, the same bronze construction and self-priming design make it well suited to industrial engines, generators, and other liquid-cooled equipment.
Q: What orientation can this pump be installed in?
A: The 18930-0010 can be mounted in any position, giving flexibility when fitting it into tight engine compartments or equipment layouts.
Q: How does the bracket mount version differ from a pulley mount version?
A: The bracket mount version is designed to bolt directly to a mounting surface using its integrated bracket, while a pulley mount version is intended to be belt-driven off an engine pulley system.
Q: What kind of hose should be used with the 1-1/4" ports?
A: Standard 1-1/4" ID hose rated for the intended fluid and operating temperature range should be used to ensure a secure, leak-free connection at both ports.
