This pump impeller Ref. 190.G is a flexible replacement impeller made of black neoprene with profile 4 for cooling water and seawater pumps on inboard engines, generator sets, and other marine installations. The impeller has 6 flexible blades and is designed with a D-shaped shaft hole with one flat side.
The impeller has an outer diameter of 40 mm, a width of 19 mm, and an internal shaft diameter of 12.2 mm. The D-shaped shaft hole provides a positive fit on a compatible pump shaft. When replacing, the diameter, width, shaft dimensions, number of blades, and profile must match the existing impeller.
The spare part cross-references to, among others, Sherwood 8000K / 08000K as well as several Onan references. In addition, there are documented cross-references to Kohler 359978, DJ Pump 09-107-0601, and JMP 7013-01. When replacing, both the impeller's dimensions, profile, hub design, and existing spare part number should be checked, as the engine or generator make alone is not always sufficient to identify the correct impeller.
Documented cross-references include Sherwood 8000K and 08000K, Onan 132-0395, 132-0407, 132-0415, 132-0430, and 132-0493, Kohler 359978, DJ Pump 09-107-0601, as well as JMP 7013-01. The Onan numbers also appear with an OE prefix in spare part data. Reference 132-0415 is also listed in connection with Cummins/Onan.
CEF 500190G / 500190.G and item no. 16.194.55 are related parallel variants with Ref. 190 geometry, but are separate products. For removal, impeller puller item no. 16.191.01 or 16.191.02 can be used depending on the pump size and connection.
