DEF Pump / Urea Pump for Truck SCR Systems

The urea pump — called the DEF pump in North America, where the fluid is sold as Diesel Exhaust Fluid — is the supply module of the SCR dosing side, and it is ordered as the complete module it is sold as. This family holds 40 catalogued entries covering Iveco, Scania, Mercedes-Benz and Volvo applications. When a pump order follows a dosing pressure fault or an SCR efficiency code, the OE number of the complete module is what the replacement is matched against, with the module's composition confirmed against its catalogue entry at inquiry.

Catalogued examples include the Iveco module referenced 504381868 / 5802855457 / 5802513619, a Scania engine urea pump referenced 2238325 / 2095566 / 2238324, and a Mercedes-Benz unit referenced HR13151714 / A0001401078. If vehicles in your market are parked outside through winter, say so in the inquiry. The matching injector can be carried on the same inquiry — the DEF injector page covers that family.

Order by OE number, not by guesswork

A urea pump is confirmed as the complete module it is sold as. Send the module OE number from the old unit, and the match is checked against the catalogue entry for that number before pricing. A photograph of the housing is a supplement to the inquiry; the module number is what the confirmation is made against. Modules already catalogued in this family include 504381868, A0001401078, 2238325. If your module number is not listed here, send it anyway: it will be checked against the vehicle application, engine and model year you provide, across the SCR families and the wider 422-entry catalogue behind this site.

Fitment confirmation checklist

For a pump order, the unit of confirmation is the complete module: quote the module OE number rather than a number taken from a sub-component, and confirm the module against its catalogue entry at inquiry. Add the vehicle model and engine; if the order follows a fault, include the fault text from the vehicle with the inquiry — that context is recorded with the order. Where a catalogue entry lists applicable models, that listing is what the confirmation is based on — if your exact model is not shown, the reply will say so plainly rather than stretch the fitment. Distributors building a stock list can send a spreadsheet of OE numbers and receive a line-by-line matched or not-matched reply.

Packaging, stock and dispatch

A pump order is packed and shipped as the complete module the catalogue entry describes, in the buyer's choice of the four packaging options offered across the range: OEMEMBER branded boxes, UAP branded boxes, blue neutral boxes and white neutral boxes, so distributors can keep their own shelf identity. On availability, more than 100 catalogued items can be dispatched within 3 days and more than 2,700 items within 15 days. A pump ordered together with its injector or level sensor is confirmed and quoted as one shipment. Warranty terms for each order are confirmed in the quotation before payment, and product certificates are available upon request. File the confirmed module number from your first order and quote it back on any repeat order.
