A unique auto-fill DEF pump by Western Global. Once installed inside your DEFCube, the AutoDEF Replenish system refills the connected equipment’s DEF tank autonomously, reducing refill times and keeping sites up and running for longer.

DEF tank pumps reimagined

Our AutoDEF Replenish is a diesel exhaust fluid (DEF) tank pump that extends run times by refilling your tank with DEF automatically. The AutoDEF Replenish senses when your DEF level is getting low and starts pumping DEF as and when needed, eliminating the need for someone to be onsite at all times. This unique, field-tested technology includes a sensor in the nozzle to make sure its correctly seated, and purge function keeps the lines clear and prevents crystallization. With a simple set-up process, the AutoDEF Replenish does all the hard work for you when it comes to refilling DEF.

Suitable for a range of equipment, the AutoDEF Replenish ensures your DEF is protected from the elements, with the fluid and cables running through an insulated cover, get in touch to see if your equipment is suitable.
