Why Pay More For Remanufactured Water Pumps When You Can Buy New?


It’s a strange situation when remanufactured water pumps are more costly than brand new HD Water Pumps from GMB.

We know that fleet managers shouldn’t pay more for remanufactured pumps than brand new pumps. That’s why GMB Water Pumps do not reuse any “old” components, allowing for stricter and more consistent quality control. With this said, you can count on GMB to be with you for the long-haul.
