This marks Oxbo’s 16th AE50 Award, highlighting its long-standing commitment to engineering excellence and innovation. AutoFill reduces on-harvester labor needs by up to 75% while improving efficiency and accuracy. During the 2025 blueberry harvest in Washington and Oregon, the system successfully handled millions of pounds of fruit.

“AutoFill marks an important first step for Oxbo in automation for berry harvesting. It showcases our ability to innovate and deliver practical solutions that advance efficiency,” said Stephen Schell, Senior Engineering Manager Oxbo Fruit. “Winning the AE50 ward affirms Oxbo’s leadership and our commitment to shaping the future of harvesting for growers.”

These results were accomplished by isolating the shaft seals from aggressive/abrasive chemicals and providing uninterrupted seal cooling and lubrication, eliminating the most common causes of centrifugal pump failure.  The system utilizes a dual shaft seal, specially formulated synthetic barrier fluid, and air pressure to ensure that the seal is always submerged in barrier fluid (not pumped fluid).  Other pump manufacturers might have similar systems, but all wet seal systems are not created equal.  Their systems only provide an unpressurized buffer fluid during critical run-dry periods, allowing contamination and providing insufficient cooling when it’s needed most.  The constant pressurization in the Oasis^® system ensures that the barrier fluid is always present between the seal faces, providing isolation of the seals and protection for extended run-dry periods. 

The Oasis WetSeal Technology first appeared in the Ace FMC-750F-HYD pump and then quickly expanded to the other MAX Series models, including the 650, 755 and 855 pumps.  Most recently, the Oasis^® system was incorporated into the company’s new Pro 5 Series products, including the 125, 155, 225, and 255 models.  These latest releases now provide the protection of the Oasis^® system across Ace Pump’s entire product range.

Ace produces thousands of Oasis^® WetSeal Technology pumps each year, with most still pumping today. This has made Ace Pump and Oasis^® the industry’s gold standard for seal reliability and one of the most requested features for new applications.
