Description

The Cat Pumps Model 3CP1120.3 is a high-performance triplex plunger pump that belongs to the heavy-duty 3CP series. This specific “.3” version is technically distinct because it features a 16.5 mm shaft, which is a specialized size often found in older European-spec motors or specific OEM power units, as opposed to the standard 20 mm shaft found on the base 3CP1120.
