Applications

Sea water pumps type F4B

The impeller is intended for sea pumps Johnson F4B series and equivalent configurations used in the nautical field. It is a typical spare part for ordinary and extraordinary maintenance on sea water circuits, where the flexible impeller is a component subject to wear.

Compatibility with Fischer Panda generators (flanged F4B pump)

The kit is suitable for regenerating the hydraulic compartment of Fischer Panda generators that use the flanged F4B pump, including:

• Panda 6000 ND / 8000 NE / 9000 ND / 12000 NE
• Panda 8000i / 10000i / 15000i

Note: before ordering it is advisable to check the spare part code and the version of the installed pump (flat gasket vs O-ring), especially if replacements or updates have been made over time.

Advantages for maintenance and spare parts

• Complete kit for the intervention: includes both flat gasket and O-ring, to manage the cover sealing variants present on the F4B series.
• Spare part identifiable by code: Fischer Panda reference 0000652 and OEM reference 09-810B-1 useful to align the order with the spare parts list.
• Assembly support: presence of glycerol lubricant to facilitate the insertion of the impeller and reduce friction during installation.
• Format suitable for onboard interventions: practical solution for scheduled maintenance, with components typically needed to close the cover.

Usage and operational notes

General replacement guidelines

The impeller replacement is normally performed during sea water pump maintenance or when signs of wear are detected. During the intervention:

• check the condition of the cover and the sealing seat (flat gasket or groove for O-ring);
• use the glycerol lubricant on the blades before insertion;
• ensure that the impeller is correctly coupled to the’single notch / spigot joint provided by the pump;
• tighten the cover evenly, following the procedures specified by the plant/pump manufacturer.

Verification tips before purchase

• Compare code 0000652 and/or 09-810B-1 with spare parts documentation.
• Check that the pump is actually a F4B (or indicated variant) and that the requested measurements match those shown.
• If in doubt about the cover version, the presence of O-ring and flat gasket in the kit helps manage the most common configurations of the series.
