This pump impeller Ref. 189 is a flexible replacement impeller for water, cooling water, and seawater pumps on Volvo Penta inboard engines and other compatible marine installations. The impeller has 12 flexible blades and is designed with a splined hub for transferring rotation from the pump shaft.
The impeller has an outside diameter of 57 mm and a width of 32.05 mm. The hub/shaft dimension is stated as approx. 14.29 / 16 mm depending on the measuring point on the splined insert. When replacing, the diameter, width, hub design, number of blades, and existing part number must therefore be compared with the removed impeller.
The spare part cross-references to Volvo Penta 21213660, 3862567, and 21951348. Volvo Penta 21951348 is a newer impeller kit and replaces, among others, previous Volvo Penta references 21213660 and 3862567. There is also a CEF reference 500189 for the same Ref. 189 geometry.
Documented Volvo Penta references include 21213660, 3862567, and 21951348. Additional older Volvo Penta numbers appear in cross-reference lists for 21951348, but the specific pump installation should always be checked before using these as a fitment reference.
CEF impeller part no. 16.194.56 / CEF 500189 is a related alternative variant with the same Ref. 189 geometry. CEF data indicates 12 blades, splined hub, Ø57 mm and 32.05 mm width.
