This pump impeller Ref. 121 is a flexible replacement impeller with profile 4 for cooling water and seawater pumps on inboard engines, generator sets, and other marine installations. The impeller has 6 blades and is supplied in a GX version as a service kit with a gasket and set screw.
The impeller is made of black neoprene and has a bore of 12 mm, an outside diameter of 39.6 mm, and a width of 19.2 mm. The shaft hub is designed for attachment via a pin or set screw. Profile number 4 identifies the design of the hub or shaft connection and must match that of the existing impeller.
The spare part cross-references to, among others, Jabsco 22405-0001, Johnson Pump 09-808B and 09-808B-1, as well as several Volvo Penta references. Additionally, there are documented OEM references from companies such as Ancor, Onan, Westerbeke, Lombardini, Nanni, and Vetus. When replacing, the impeller's dimensions, profile, hub design, and existing part number should always be checked, as the engine make alone is not always sufficient to identify the correct impeller.
Documented cross-references include Jabsco 22405-0001, Johnson Pump 09-808B and 09-808B-1, Volvo Penta 875583, 875583-7, 833995, 21951342 and 3586496, Ancor 50021 and 2048, Lombardini 42001940, Nanni OE970434013, Onan 132-0310 and OE132-0311, Westerbeke 46622 and 32620, Vetus IMP00601, JMP 7000-01, DJ Pump 08-31-0601, as well as CEF 500121 and 500121GX.
Johnson Pump applications include, among others, the F35 system and F35B-8 pumps. Documented Nanni model designations include FK2,40E/HE, 2,60H, KLA, L30 and 3.90. The specific raw water pump can vary between engine versions and production years, and the part number of the pump or existing impeller should therefore always be checked before ordering.
