This pump impeller Ref. 146.X is a flexible replacement impeller made of black neoprene with profile 9 for water, cooling water, and seawater pumps on inboard engines and other marine installations. The impeller has 10 flexible blades and is designed with a transverse pin drive.
The impeller has an outside diameter of 51.8 mm, a width of 22 mm, and an internal shaft/hub diameter of 12.17 mm. The hub is designed for a transverse drive pin, which transfers rotation from the pump shaft to the impeller. When replacing, the diameter, width, shaft dimension, number of blades, profile, and drive design must match the existing impeller.
The spare part cross-references to, among others, Jabsco 18653-0001, Lombardini 42002040, and JMP 7070-01. In addition, there are documented cross-references to Vetus 00701 / IMP00701 as well as CEF 146 / 500146 / 500146X. When replacing, both the impeller's dimensions, profile, hub design, and existing spare part number should be checked, as the engine or pump make alone is not always sufficient to identify the correct impeller.
Documented cross-references include Jabsco 18653-0001, Lombardini 42002040, JMP 7070-01, Vetus 00701, and IMP00701 as well as CEF 146, 500146, and 500146X.
Documented Nanni Diesel engine models include FK3, 2345H2, 2.50HE, 2.60HE, 3.75HE, 3.90H/HE, 4.110.H, and 4.410.M. The impeller is also linked to relevant Lombardini and Vetus installations via the documented OEM references, but the specific pump and the original spare part number should always be checked before ordering.
CEF impeller item no. 16.194.43 / CEF 500146X is a related alternative variant with the same reference and main geometry, but it is a separate product. For removal, impeller puller item no. 16.191.01 or 16.191.02 can be used depending on the pump size and port dimensions.
