1111 Blue Run-Dry Impeller | Globe 01-12-1690

Globe 1111 Blue Run-Dry Impeller | 01-12-1690 | Brandonite | 12-Pt Spline | Caterpillar 3N5895 Jabsco

The Globe #01-12-1690 is the 1111 Blue run-dry impeller manufactured from Globe's Brandonite compound — a high-strength, self-lubricating elastomeric material guaranteed to run dry for 15 minutes without damage. The 1111 Blue is a wide-body 12-point spline impeller with a 3" axial width, delivering significantly higher displacement per revolution than other Globe 12-pt spline impellers at the same 2-9/16" OD — designed for the high raw water flow demands of Caterpillar marine diesel engine cooling pumps. Does NOT include gaskets or O-rings — order separately. Delivers up to 3x the service life of standard rubber, nitrile, or neoprene impellers. Water applications only.

Additional Information

1111 Blue vs. 100 Blue — Same OD and Spline, Different Width:

The 1111 Blue and 100 Blue share the same outer diameter (2-9/16" / 65 mm) and 12-point spline drive, but differ critically in width:

• Globe 100 Blue (01-12-1060) — 2" (51 mm) wide; replaces Caterpillar, Cummins, Ford Lehman, Jabsco, Volvo; includes gaskets — see the Globe 100 Blue (01-12-1060)
• Globe 1111 Blue (01-12-1690) — 3" (76.2 mm) wide; replaces Caterpillar 3N5895/4N6582; does NOT include gaskets

The 1111 Blue's 3" width delivers 50% more displacement per revolution compared to the 100 Blue's 2" width at the same diameter. These impellers are not interchangeable — always confirm by OEM cross-reference and verify width against your pump housing depth before ordering.

Caterpillar Marine Diesel Application:

The Caterpillar 3N5895 and 4N6582 cross-references indicate the 1111 Blue fits Caterpillar marine diesel raw water pump applications. Caterpillar marine engines (3200, 3300, and 3400 series, among others) use high-displacement raw water pumps requiring a wide-body impeller to meet their cooling flow demands. The Globe 1111 Blue's Brandonite compound is well-suited to the demanding service conditions of commercial marine diesel operation — continuous duty cycles, high water temperatures, and limited opportunity for planned maintenance downtime.

Brandonite Run-Dry Technology:

• 15-minute guaranteed run-dry rating — standard impellers fail in under 30 seconds dry
• Up to 3x service life vs. rubber/nitrile/neoprene under normal wet operation
• Post-dry-run serviceability — inspect after a dry-run event within the rating; if undamaged, can return to service without mandatory replacement

Frequently Asked Questions

1. Does this impeller include gaskets and O-rings?
No — the Globe 01-12-1690 does not include gaskets or O-rings. Order the appropriate gasket and O-ring set for your Caterpillar or Jabsco pump separately. This is different from the Globe 100 Blue (01-12-1060), which includes gaskets at the same OD and spline drive.

2. How do I confirm this is the correct impeller for my Caterpillar marine engine?
Cross-reference against Caterpillar 3N5895 or 4N6582 in Caterpillar's parts documentation for your specific engine model and serial number. Verify the 3" width fits your pump housing depth — the 100 Blue at 2" wide will not fill the housing correctly in a pump designed for the 3" 1111 Blue. Contact us at MacombMarineParts.com with your Caterpillar engine model and serial number for fitment confirmation.

3. What is the service interval for this impeller on a Caterpillar marine diesel?
Caterpillar marine diesel raw water impeller service intervals vary by engine model and operating hours. Consult your engine's Operation and Maintenance Manual (OMM) for the recommended inspection and replacement interval. In commercial marine service, annual replacement regardless of hours is common practice. Inspect the impeller at each cooling system service; replace immediately on any sign of vane cracking, deformation, or hub degradation.

4. Why does pump housing width matter when selecting an impeller?
The impeller must fill the pump housing from end plate to cover to create proper flow. An impeller that is too narrow for the housing leaves a gap that allows recirculation — raw water passes around the impeller rather than being pumped forward, reducing flow and cooling capacity. An impeller that is too wide will not fit in the housing at all. Always verify impeller width matches pump housing depth when cross-referencing impellers across Globe designations.
