SEEPEX extends smart maintenance concepts with Drive Joint Access for open hopper pumps
The specialty of open hopper pump design is the conveying of viscous products with little flowability. The maintenance of these kind of pumps has been time-consuming and complicated in the past due to valves and hoppers obstructing access to the pump.
To solve that problem SEEPEX is now introducing the patented Drive Joint Access (DJA) technology on some of their open hopper pump ranges, significantly reducing maintenance times and costs. Between feed hopper and lantern a detachable joint casing is mounted on rollers, which allows access to the drive-side joint. Mechanical seal, plug-in shaft and drive can be quickly installed or removed on site - without removing the feed hopper, the screw conveyor or the rotor-side joint. This simplifies the work and reduces maintenance and downtime from three to four days to less than one day, thus significantly reducing costs. A regular, simple and quick check, for preventive maintenance of drive side components whilst pump is in situ is now also possible at any time.
Depending on the range it is also possible to replace the ribbon screw without dismantling the feed hopper and compression zone. With DJA, the pump can now be dismantled from drive-side for the first time. The removal of components and the use of heavy hoists are a thing of the past:
The advantages of Drive Joint Access at a glance
In situ service:
No pipework removal, no heavy lifting equipment
Significantly reduced maintenance costs:
No disassembly of rotor/stator, screw and hopper
Regular, easy and quick check of joint side components
Pro-active inspection and maintenance of the drive-side parts ensures trouble-free Operation
