Krones is premiering its own pump series called Evoguard. The first product in this series developed in-house is a single-stage, normal-priming, hygienic centrifugal pump.
The quality assurance system applied for the Evoguard series of pumps corresponds to Krones’ tried-and-tested quality control concept, with batch tracking provided for each and every component, which can on request be confirmed by the relevant certification. And the “Made in Germany” attribute also attests to the pumps’ superior quality. The one-stop-shop principle, in conjuction with process engineering from Krones, promises an optimum line layout coupled with maximum process dependability.
This premiere at the drinktec was preceded by purposeful development work, rigorously focusing on the requirements posed in a production operation and tapping into long decades of experience gained in plant manufacture while all the time liaising closely with the project engineers involved. All of this effort has culminated in a cost-efficient modularised system with sizes that have been optimally matched to suit the product being handled in each case.
As the system is in modularised design, inventories for wear parts at the client’s facility are reduced. The hygienic centrifugal pump is available for delivery flows of up to 100 cubic metres an hour, delivery heights of up to 80 metres and operating pressures of up to PN 16.
Gentle product delivery
Accurately designed flow paths, with all dead spaces eliminated, mean that the centrifugal pump provides uniform and gentle delivery of the product while also assuring top quality levels. At the same time, Krones has placed great emphasis on minimising the pumps’ service routines, so as to reduce both the time and manpower required for their cleaning and maintenance, which means there are significantly fewer production interruptions for purposes of the requisite servicing routines. For its Evoguard pumps, Krones has developed a new interface with the motor, plus a new seal concept for maximised dependability even when exposed to ultra-tough process conditions, with concomitantly extended useful lifetimes. In terms of operating costs, high-efficiency motors coupled with optimised pump design ensure low energy consumption.
Seals are replaced swiftly and easily
As far as safety is concerned, reliable preclusion of any injury risks during operation has been a top priority, creating a design in compliance with statutory stipulations as laid down in EU Machinery Directive 2006/42/EC. The TÜV SÜD technical inspectorate conducted the requisite design examination, including pressure tests, safety tests, checking the pumps’ mechanical strength, etc. Swift and easy seal replacement in the product compartment without any special tools, plus simple setting of the gap dimensions, likewise requiring no special parts, ensure risk-minimised care and maintenance work.
