Johnson F4B-19 Flexible Impeller Pump - 12v
Match your marine pumping application to the F4B-19 Flexible Impeller. Product 10-24689-01 is the 12 V version, with its own current and fuse requirements.
The DC-driven flexible-impeller pump is intended for bilge, deckwash and fresh-water duties, with oil and diesel transfer also listed as applications. Check the selected liquid and installation against the pump instructions.
The heavy-duty motor is paired with a bronze body, lip seal and the specified impeller. A vacuum switch can be used for an appropriate automatic arrangement, subject to matching the control to the installation.
Check both the available mounting space and the route into each port. Leave sufficient access to the pump head and service parts, and match the complete electrical or mechanical drive arrangement before installation.
Choosing and using this product
A flow figure alone does not describe the complete installation. Hose routing, outlet height and the rest of the plumbing can affect the delivered result. Use the relevant pump guidance when sizing the system rather than treating a catalogue flow figure as a guaranteed output at every outlet.
For this version, connection: Hose 1” / 1/2” BSP. Use that specific detail when comparing the item with your existing equipment or planned installation. Other sizes and configurations in the range should be checked separately rather than treated as equivalent.
Compare the package contents with the complete installation you are planning. Pump-only listings and kits can differ in switches, fittings and hoses. Listing the required components before ordering helps you select the appropriate package and avoids treating an illustrated accessory as an included part.
For a service part, identify the existing pump model before ordering. A motor cartridge, switch, strainer or valve renews only its stated part of the assembly. Check adjacent hoses and connections at the same time so an unrelated problem is not mistaken for a failed replacement component.
