Description

The AR (Annovi Reverberi) RKA4G40HN-L is the specialized “Long Shaft” version of the standard RKA series. While it shares the same internal “wet end” specs as the standard RKA4G40HN, the extended crankshaft is specifically engineered for easier pulley alignment in belt-drive systems or to accommodate thicker mounting brackets.

The “-L” suffix is the most important part of this model number if you are replacing an existing pump, as it ensures your pulleys will line up without having to shim or modify your equipment frame.
