Useful Information

Description and Purpose:

In modern SCR systems, stable DEF delivery matters just as much as correct dosing. This Genuine Denoxtronic 2.2 DEF Pump by Cummins with Part Number: 4817931, supplied in new condition, supports that balance by supplying fluid evenly and predictably during normal vehicle operation. With a 12V drive, 10-pin electrical connection, and dedicated inlet and outlet fittings, it integrates cleanly into the DEF circuit without unnecessary complexity.

Why Replacement is Important:

A worn or failing DEF pump can interrupt fluid flow, triggering system faults or emission warnings. Replacing it restores proper DEF circulation and helps avoid derate conditions caused by dosing irregularities.

Impact on Vehicle Performance:

Ensures steady DEF supply to the SCR system, supporting reliable emissions control and consistent vehicle operation under everyday driving conditions.

Manufacturer Information:

Cummins® manufactures emissions system components designed to meet OEM standards, focusing on durability, precise integration, and dependable operation in heavy-duty and on-highway applications.
