May 2010 | Multi rake screen KHU Zahedan/Iran

Robust, reliable and long-lasting machines for the toughest cases of operation are required and inquired worldwide.

While many manufacturers "optimize" their machines for cost reasons over and over and are willing to cut back in robustness and long-life cycle at the same time, company KUHN forceful strikes the path of "best practice".

The multi rake screen KHU can suitably be used at widest and deepest channels. Through the Patermoster lift effekt moved masses and therewith the forces on chains, wheels and bearing can be reduced to a minimum.

While competitors offer  the cheapest chains made out of plastics or galvanized materials, with KUHN strictly only hardened high-grade steels are used in highest quality. Also customers from Iran have learned to estimate the amenities of the KHU and ordered another multi rake screen. After all necessary duty and delivery formalities were effected and executed by the public agencies, a final inspection took place at KUHN GmbH. Under survey of strict inspectors the carrier box was closed and sent on its journey to Iran. We thank for this order and are certain that this machine shows a great future investment in the long term for the customer.

May 2010 – Waste Water Treatment Plant Großzimmern

Extensive replacements at the Waste Water Treatment Plant Großzimmern in the adminisstrative district Ddarmstadt-Dieburg are drawing to their end.

Two totally different subsections have been transacted simultaneous of company KUHN. Thereby we have proven again, that our customers can rely on our core competence as plant manufacturer as well as experienced mechanical engineers.

On the one hand the mechanical sludge thickening was renewed. The gotten long in the tooth tickener centrifuges were replaced by modern, powerful aggregates. The ancillary units like feeding pumps, flocculating agent-conditioning units and mountings that are necessary for operation were also renovated. Especially the old units failings were considered into the new planning, so that the by KUHN built handling devices of model KSF function to complete satisfaction when evacuating the dried mud. Besides the evacuation of the mud to an especially therefore built mud storage for storing and final drying the mud can be – also through clever configuration of the intermediate dropping possibilites – derectly dropped into transport vehicles.

The complete reconstruction was also reset electro- and control-technical by us. All the switchboards were furnished with the most modern communication possibilities and process visualization. This showed that the philosophy „all in one hand“ brings great advantages for the customer.

On the other hand the machine for mechanical purification was also replaced through a new one. Since there is a very narrow channel for the existing inflow amount a Step Screen of model KSR-S was able to score especially well. The extra narrow built side cheeks of this screen model leaves a lot of space for theeffective filter area. That is why it is possible to still apply the approved filter step method in the smallest channels – and that at remarkably low accumulation heights.

The upstream Step Screen KSR-S works to the indestructible built Screenings Washing Press of model KWP of KUHN. With brilliant washing performance and gigantic press capacities this machine is widely known as a reliable Washing Press. Many cheap articles, also of famous manufacturers, are not nearly able to enduring fulfill the same, what comparison tests have clearly poven. Thecontrol system was also built at KUHN, because nobody knows its machines better than the manufacturer itself.

We thank the Eigenbetrieb Abwasserbeseitigung Groß-Zimmern for the entrusting KUHN and the made decision.

May 2010 | Clubatmosphere in the work hall - Rythm in time of the machines - Grenzgänger of the jazz in the border triangle.

“Jazz work" is an initiative of regional artists and enterprisers which has sat down to the purpose to enrich the cultural scenery in the region Neckar-Odenwald-Tauber. To the initiators belong Willi Pfannenschwarz for the company Seitenbacher (Buchen), Christoph Schneider for the OKW group (Buchen), Michael Kuhn for the company Kuhn (Höpfingen), Hannes Wolf for the company Aurora (Mudau) and Bernhard Berberich for the bank Volksbank Franken. The artistic part perform official duties of Christian Roo (music) and Bichan Maschajechi (art). The enterprises involved up to now operate as sponsors and as an organizer for the arrangements which take place in their work halls. Now after the exceedingly successful première concert of the initiative "jazz work" in last autumn starts the second round of the arrangement row which was brought to life by artists and enterprisers of the region to be able to offer an adequate platform and the local audience jazz at the highest level to prominent jazz musicians of the Metropolregion. The second event of the jazz work row takes place on the 08th May at 20 o'clock (admittance from 19 o'clock) in the company building of the company Kuhn (Franz Kuhn Str. 1-3, 74746 Höpfingen). Cards can play in all branches of Volksbank Franken or on www.jazzwerk.com are booked. Also this time the initiators have succeeded in winning some of the most put a tread jazz musicians of the Metropolregion for jazz work: Sandra Klinkhammer who finished a study in jazz and pop song after her classical clarinet study and can prove a several years' successful activity as a lecturer in the field Jazz and pop song at the music school JMK to Buchen and will present in Höpfingen her album "angel's tongues", forms as well as Albérto Menéndez, which with his 4-headed "Alberto Menéndez Group" the second part of the evening and will introduce a choice of own compositions. Meeting the expressive, from an uncontrollable grooving to done compositions of Alberto Menéndez with the soulful songs of Sandra Klinkhammer promises an especially exciting and diverse concert experience which one should not allow to escape himself. (Other infos on www.jazzwerk.com) the jazz work arrangement in Höpfingen is a partner arrangement of the "Jazznight" at the same time taking place in Buchen: who would like to allow to end the evening not with the Clubathmosphäre of jazz work, but on the Buchener Jazznight, receives at the exit Jazznight-entry badges.

22 April 2010 | Second Screw Pump was mounted in Kochertürn / Jagst

On this the report of 4 May 2010 in Heilbronner "Stimme":

Heavy weight purrs

By Ute Plückthun

Neuenstadt - Dodgy challenge at the main Kochertürner pumping station: at precision job and while operational the second of the two new Pipe Screw Pumps was assembled. All together the Zweckverband Abwasserbeseitigung Unteres Kochertal invested 390 000 Euros in the general refurbishment, which should be completed by the end of May.

The compact Pipe Screw Pump weighs ten tons and is waiting on the grass to be mounted. Its 30-year-old forerunner is meanwhile being loaded onto a heavy duty vehicle for scrapping. From the outside it looks rusted. On the inside its blades are worn out, that is the reason why the delivery rate bates, the graduate engineer declares Michael Kuhn, managing partner of company KUHN in Höpfingen, which is specialized in technical installations.

„It has far crossed the average durability of 20 years“, affirmed the mayor of Neuenstadt Norbert Heuser. A crane is on-site to assemble the new Steel Pump into the pumping station. No easy undertaking, ultimately the 14,60 meter long pump shall already be set in the later necessary 40-degree-angle when unlaoding. Again and again the supervising service engineer Siegbert Hilpert measures with the spirit level, multiple times the chain links on the crane have to be adjusted. „We rather bother to this now, because once you get down there it’s hard to reach“, says Kuhn. That is not the only complicated situation. „Relatively challenging was to keep the water running the entire time“, says engineer Dagmar Feinauer of the Bitzfelder Ingenieurgesellschaft Nußbaum, who is responsible for the planning and surveillance acticities. To this only few meters away submersible motor-driven pumps came into operation, a double pump line was installed as a bypass. Meanwhile to the beginning of the year the first of the two Pipe Screw Pumps could be renovated in the main pumping station, after the sump on the chamber ground was dried up and furnished with a separating plate between the two pumps. The first pump already purrs since end of January and boosts the incoming sewage water with a capacity of 115 l/sec out of Hardthausen, Neuenstadt and Dahenfeld, so it can be transported to the Verbandskläranlage in Stein. After about an hour the second Pipe Screw Pump is seated in its hopper and is  screwed tightly. Middle of May the also net 40 000 euro twin sister will be ready to operate. „One of the two pumps is always in operation, when it is raining hard, both of them are required“, declares Feinauer their function and brings out their durability, robustness and economy. With the mounting at the „most important spot in the whole pipe network“ Heuser is just as satisfied as Kuhn. Closing the in its concrete constancy partial reconstructed hopper shall now be completed and receive a trapezoid roof.

May 2010 | IFAT fair China

Our manager Jürgen Kuhn took part on the 5th and 6th May, 2010 on a communal state of the German Water Partner Ship GWP on the fair IFAT in China as a representative of our company.

It was a very interesting business trip with which many new contacts could be attached.

March 2010 | Delegation trip to Spain

Manager Michael Kuhn took part from 15. - 18.03.2010 in an economic delegation trip to Spain under the direction of Minister for Economic Affairs Ernst Pfister.

Dec. 2009 – March 2010: Christmas Island, Australia

Shortly before Christmas, an extraordinary quite unusual gift arrived at KUHN water experts: sending us a rush order, the Australian government entrusted us through our local agent with the delivery of two KKA headworks units.

A look at the map led us in the middle of the Indian Ocean between Indonesia / Java and Australia to the lonesome Christmas Islands.

With the receipt of the order, a race against time began. Many technical details had to be clarified, since both headworks units had been ordered with the complete measuring and switching device engineering. Besides questions concerning suitability for transport and necessary safety classes all the basic materials had to be examined most thoroughly.

While both headworks units were running through manufacturing steps, the complicated question about how to handle this large air freight had to be resolved as well.

Due to the urgency it was decided for an adventurous cargo trip to the Christmas Islands: the headworks units will be on their way to their place of destination by land, air and sea: the first 600 km from Höpfingen to Amsterdam/NL per truck – the moment of truth being the loading into a wide-bodied aircraft showing whether the measurements of the transport boxes have been accurately observed – after traveling half the world by plane, the boxes will be loaded on an “Express-Truck” in Sydney/Australia. Two truck drivers will cover the distance of 4.000 km from Sydney to Perth driving day and night – in Perth, the shipment to the Christmas Islands that is just as long as the journey before carried out by a shipping company.

Since both of the headworks units KKA have already been tested at KUHN, we are sure that they will soon run reliably.

March 2010 – raw sewage pumping plant Kochertürn

The project partners of KUHN almost reached the limits of what is technically possible at the pumping station Kochertürn of the association for sewage treatment (AZV) “Unteres Kochtal”.

2 Archimedean screw pumps of the former Swiss model “Trummer” had gotten a bit long in the tooth and had to be replaced. One of the screws even dropped out of order due to a burst pipe.

At first sight, this order was actually not an unusual task for the specialists of KUHN, but owing to the impressive technical dimensions it became a challenge for everybody.

No other screw pump configuration is able to master similar conveyance hights. At a total length of 14,6 m, the resulting bending has to be held as low as possible.

With these double-flight screws, the jacket tube and the center tube are fixed and inseparably combined with each other. After the inner screw had been produced, the bifid jacket tube with a diameter of 1100 mm on both sides had to be moved over the internal screw.

Therefore, the production tolerances had to be kept within the narrowest limits. This job was a masterstroke of our workshop and with a total weight of nearly 12.000 kg a borderline case for our assistive technology.

After the mutual factory approval with the principal – the AZV Unteres Kochertal – and the Nussbaum engineering consultants from Bretzfeld, the first of the two commissioned screws could be authorized for assembly. Both loading and transport starting at KUHN’s factory turned into an adventure.

The unloading and the positioning of the screws at the site turned out to be very difficult as well, because after the heavy lorry transporter had been unloaded it got stuck in the winter landscape of Kochertal. With the help of two tractors and the uncomplicated, courageous action of the staff, it was possible to “release” the forwarder and to build in the screw.

We thank the AZV Unteres Kochertal for their downright confidence and are looking forward to soon being able to give an account of a successful start up.

03rd March, 2010 | Visit old mayor and county commissioners
