025 Blue Run-Dry Impeller | Globe 01-12-0965

Globe 025 Blue Run-Dry Impeller | 01-12-0965 | Brandonite | Single Flat Drive | Jabsco Raritan Johnson

The Globe #01-12-0965 is the 025 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 025 Blue uses a single flat drive hub (also called a D-bore or single flat shaft) and composite core, making it a common replacement impeller across raw water cooling pumps, bilge pumps, and marine sanitation device (MSD) pump applications including Raritan marine toilets. Includes matching gaskets and/or O-rings. Delivers up to 3x the service life of standard rubber, nitrile, or neoprene impellers.

Additional Information

Single Flat Drive — What It Is and Why It Matters:

A single flat drive shaft (also called a D-shaft or single flat bore) has one flat machined along its length. The impeller's bore has a matching flat, which prevents the impeller from rotating on the shaft independently of the shaft's rotation. This is a different drive system from pin drive, spline drive, and keyed shaft drives. Always confirm your pump shaft drive type matches the impeller before ordering — a single flat impeller will not seat or transfer torque on a keyed, pin, or spline shaft.

Raritan MSD Application — Run-Dry Impeller Advantage:

The Raritan CH13 cross-reference indicates the 025 Blue is used in Raritan marine sanitation device (MSD) pumps, including Raritan marine toilet systems. MSD impeller pumps are particularly prone to dry-run events — a toilet that runs without sufficient water, a low-water holding tank level, or an air-locked pump line can all cause the pump impeller to run dry. Standard rubber impellers in MSD applications fail rapidly from dry-run damage; Globe Brandonite's 15-minute run-dry guarantee makes it the correct specification for these applications. The 025 Blue's run-dry capability also reduces the frequency of emergency impeller replacements in a bilge or sanitation pump context where access may be difficult.

Frequently Asked Questions

1. How do I confirm this impeller fits my pump?
Cross-reference part #01-12-0965 — or the OEM numbers it replaces — against your pump's parts diagram. Verify drive type (single flat), outer diameter (2 in. / 51 mm), width (7/8 in. / 22 mm), shaft diameter (5/16 in. / 8 mm), and blade count (6). For Raritan applications, cross-reference against Raritan CH13. Contact us at MacombMarineParts.com with your pump model if you need fitment confirmation.

2. Does this impeller fit my Raritan marine toilet?
The Globe 01-12-0965 replaces Raritan CH13, which is used in select Raritan marine sanitation device (MSD) pump models. Verify the Raritan CH13 is the correct impeller for your specific Raritan model using Raritan's parts documentation before ordering. Contact us at MacombMarineParts.com with your Raritan model number if you need fitment confirmation.

3. What is the advantage of a run-dry impeller in a Raritan or bilge pump application?
Standard rubber impellers in MSD and bilge applications fail rapidly from dry-run events — a toilet that pumps against a closed or restricted line, an air-locked hose, or a low-water condition will cause a standard impeller to fail within seconds. Globe Brandonite's 15-minute run-dry guarantee significantly reduces the risk of impeller failure from these common operating conditions, reducing downtime and the frequency of impeller replacements in hard-to-access pump locations.

4. Does this impeller include gaskets and O-rings?
Yes — the Globe 01-12-0965 includes matching gaskets and/or O-rings for the pump cover. Replace all included sealing components at each service — do not reuse the old gasket or O-ring when reinstalling the pump cover.
