This pump impeller Ref. 101 is a flexible replacement impeller with profile 7 for water, 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 design with a gasket and setscrew.
The impeller has an outer diameter of 50.8 mm, a width of 22.1 mm, and a shaft/hub size of 12.17 mm. Profile number 7 identifies the design of the hub or shaft connection and must correspond to the existing impeller. Sister variants may have the same outer dimensions but a different shaft diameter or hub design and are therefore not necessarily interchangeable.
The spare part cross-references to, among others, Jabsco 653-0001, Johnson Pump 09-0810B / 09-810B, and Yanmar 128990-42200. In addition, there are documented OEM references from, among others, Vetus, Westerbeke, Lombardini, and Nanni. When replacing, the impeller's dimensions, profile, hub design, and existing spare part number should all be checked, as the engine make alone is not always sufficient to identify the correct impeller.
Documented cross-references include Jabsco 653-0001, Johnson Pump 09-0810B / 09-810B, Yanmar 128990-42200, Vetus STM 8061, Westerbeke 34440, Lombardini 42001960, Nanni 434014, JMP 7050-01, DJ Pump 08-39-0601, and CEF 500101GX.
The impeller is used, among others, in the Johnson Pump F4B-9 and F4B-902 / F4B-903 pump families. Documented pump references include Johnson 10-35333-01, 10-35355-01, 10-35725-01, 10-24509-02, 10-35167-2, 10-35241-2, 10-24165-2, 10-24166-2, 10-24214-2, 10-24509-01, and 10-35142-2. The Vetus reference STM 8061 is, among others, linked to the Vetus M3.28.
Documented Westerbeke generator series include, among others, 4.0 BCD, 4.4 BCD, 4.4 WMD / 3.3 WMD, 5.0 BCD / 4.0 BCD, 5.0 BCDA / 4.0 BCDA, 5.0 BCDB / 4.0 BCDB, 6.0 BCD / 4.5 BCD, 7.6 BTD / 5.7 BTD, 7.7 WMD / 5.8 WMD, 8.0 BTD / 6.0 BTD, 8.0 WMD / 6.0 WMD, 10.0 BTD / 7.5 BTD, 10.0 BTDA / 7.5 BTDA, 11.0 BTD / 8.3 BTD, 11.0 WMD / 8.3 WMD, 12.5 BTD / BTDA / BTDB with corresponding 9.4 models, 12.5 WMD / 9.4 WMD, and 15.0 BTDC / 12.0 BTDC.
