KUHN KWS Archimedean screw pumpHardly any other machine in the waste-water sector provides as manybenefits as the screw pump attributed to the Greek scientist andmathematician Archimedes.
• Extremely durable, low-maintenance and operationally reliable
• Unparalleled efficiency with large control range (no loss of suction power or pressure)
• Gentle conveying process for biological cul-tures. No adverse effect on the sedimenta-tion properties and floc structure - this substantially facilitates the treatment of waste water
• Conveys raw waste water with the coarsest impurities and additional screening at
pump stations is avoided
• The Archimedean screw pumps are extremely resistant to blockage
• Service with shorter response durations for all makes and types
Cost-effectiveness Although the screw pump system is highly resistant and can "copewith" many faults and errors, the service life - and hence the cost-effectiveness - depends on how optimal the concept is, along with theexperience of the manufacturer.
As Germany's oldest and largest manufacturer of screw pumps, wehave been providing robust and sustainable solutions for over 40years.
KUHN is the only manufacturer with complete mastery over alltypes of troughs, from rotating casing troughs to special thin-layer
mortar troughs, and which can determine, design and build theoptimal system for you. After all, there are no poor solutions, just
incorrect applications!
RectificationWith regard to the rectification of existing plants, the optimal solutionshould be combined with the most cost-effective rectification process.With our close contact to the leading concrete restoration companies,we are able to offer you unrivalled cross-sectoral expertise. In thisway, we can even accommodate the demands of older optionalbuildings, some of which have been standing for 40 - 50 years.
Design (technical features)The superior design - of both the components and the screw itself -ensures extremely cost-effective operation and the long-term securityof your investment.
The trough, as an integral component of the machine, is particularlyimportant. The most cost-effective variant is dependent on whichsystem is optimal; hence, only an experienced expert can determinea sustainable solution for you and provide advice regardless ofsystem.
Some examples of types of trough are given below:
Open troughs:
• Site concrete
• Special mortar system
• Prefabricate stone trough
• Basalt tiles
• Steel/Hardox troughs, self-supporting with a compact design
• Steel/Hardox troughs for grout with concrete
Closed troughs:
• In stationary pipe (self-supporting, compact design)
• In rotating pipe sleeve (self-supporting, compact design)
The KUHN systemAs an owner-managed family business with locational ties for morethan 85 years, we feel that we have a personal obligation to ourcustomers and our employees. As a result, we have employees withmany, many years of service and consequently unrivalled, extensiveexperience as regards sales, project management, production andassembly.
