Exchange Program
If you are looking to minimize downtime, consider our Refurbishment Exchange Program. With this program, we will keep a certain number of pumps on the shelf, solely for you. When you return a NAVAC pump for repair, we will ship one of the pumps from stock to you while you send back the other pump for repair. This way, your process is not down and waiting on a pump. Once we receive your old pump, we will refurbish the pump and put that back into the stock program for you. Reach out to NAVAC directly or your local Authorized NAVAC partner for more details.
Trade-In Program
Think of this like a cell-phone trade-in program, but for pumps! The NAVAC replacement program is meant to be simple. You can send in your older pumps, regardless of age, functionality, or brand. Once we receive the older pump, we will provide a credit to you for the purchase of a new NAVAC pump. Reach out to NAVAC directly or your local Authorized NAVAC partner for more details.
