Description

Johnson Pump F3B-19 Multi-Purpose Utility Pump | 5.5 GPM – 12V (10-24516-03)

The Johnson Pump F3B-19 Multi-Purpose Utility Pump 10-24516-03 (Model F3B-19) is a versatile, heavy-duty flexible impeller pump designed for a wide array of marine and industrial utility tasks. This positive displacement pump is engineered to handle everything from bilge pumping and deck washing to water ballast transfer and engine oil evacuation (when equipped with the correct impeller).

Rugged Reliability & Self-Priming Power

The F3B-19 is built with a high-quality bronze body and a stainless steel shaft, ensuring it can withstand the corrosive nature of saltwater and harsh chemicals. Unlike centrifugal pumps, the F3B-19 is exceptionally good at self-priming, capable of pulling a vertical lift of nearly 10 feet instantly. This makes it an ideal choice for mounting in high, dry, and accessible locations while still effectively clearing water from the lowest parts of the keel.

Key Features:

• High-Torque Motor: A powerful 12V DC motor designed for heavy-duty cycles and demanding transfer tasks.

• Self-Priming Capability: Primes up to 9.8 feet (3 meters) vertically, providing incredible installation flexibility.

• Compact Bronze Housing: Robust cast-bronze construction provides maximum durability and long-term resistance to electrolysis and corrosion.

• Multi-Fluid Versatility: While standard with an MC97 impeller for water, it can be fitted with a Nitrile impeller for transferring diesel or light oils.

• Ease of Maintenance: The simple front-cover design allows for rapid impeller inspection and replacement without the need to disconnect plumbing.

• Positive Displacement: Unlike centrifugal pumps, the F3B-19 maintains a steady flow even when pushing against significant head pressure.

• Ignition Protected: Safe for installation in engine compartments of gasoline-powered vessels.

Why Choose the Johnson Pump F3B-19 Multi-Purpose Utility Pump F3B-19?

The Johnson Pump F3B-19 Multi-Purpose Utility Pump 10-24516-03 is the “Swiss Army Knife” of marine pumps. It is favored by offshore sailors and commercial fishermen who need a reliable utility pump that can be used for emergency dewatering or as a backup for multiple onboard systems. Its bronze construction ensures that it is a permanent piece of equipment, not a disposable plastic component.

Installation Pro-Tip:

For applications involving oil or fuel transfer, you must replace the standard MC97 impeller with a Nitrile impeller (Part 09-808B-9). Standard water impellers will swell and fail prematurely if exposed to petroleum products.
