Rotor Joint Access (RJA) and Drive Joint Access (DJA) are an intelligent maintenance concept for open hopper pumps.
On the one hand, RJA - a casing part that slides over the stator - allows quick and effortless access to the rotor-side joint for easy maintenance without dismantling the pressure branch or stator. On the other hand, the patented DJA solution allows easy access to the drive-side joint via a sliding joint casing mounted on rollers. The plug-in shaft and drive can thus be installed and removed within a few minutes without removing the feed hopper, screw conveyor or rotor-side joint. This drastically minimizes service work and maintenance downtimes for your pump. Moreover, openings for flushing allow easy cleaning.
