SCRAPER MADE OF PE

PE - HD, PE - MD, PE - LD, PE - el



Montabaur, 27.09.2018

In cooperation with a partner for the injection molding technology, we have access to newly developed scrapers made of PE. The scrapers are used in the fields of chemistry, industry, food technology and also in the disposal.

Qualities available are PE-HD (color RED), PE MD (color BLUE and ORANGE), PE-LD (color white natural) and PE-el (electrically conductive).

The sale of scrapers made of PE (formerly Fuchs & Partner) takes place worldwide and is a cost-effective and quality-oriented alternative to the previous products on the market.








 


INDICATOR CARTRIDGE FOR
ACID AND LAUGE



Montabaur, 18.06.2018

On the already developed SDA 90 - SDA 350 acid vapor separators, we adapt so - called INDICATOR CARTRIDGES for the indication of ACID and LAUGE as optical indication for the saturation of the granules used for acid vapor separators.

For installation, only the security label has to be removed and the cartridge screwed on.

When using granulate filling, the INDICATOR turns from BLUE to YELLOW when using acidic vapors, and when using lukewarm vapors, the color changes from BLUE to WHITE.

As soon as the user detects the color change, both the granules for the SDA and the INDICATOR are used up.

This technical solution gives you security when dealing with acid and alkalis and you will recognize the change interval immediately after outgassing of the acid and lye on the color change.

PIPES, FITTINGS AND CONNECTIONS MADE OF GLASS FIBRE REINFORCED POLYESTER RESINS (UP-GF)
IN ACCORDANCE WITH DIN 16 965 / DIN 16 966

DN 25 - DN 1000



Montabaur, 28/06/2017

Kwerk GmbH has won one of the leading manufacturers for pipes/fittings made of glass fibre reinforced polyster resins (UP-GF) for the B2B platform.

With the new assortment, Kwerk GmbH could close an important gap in the field of composite materials, like PVC-U/UP-GF, PEHD/UP-GF, PP-H/UP-GF, PVC-C/UP-GF and PVDF/UP-GF.

We are looking forward to this fruitful international cooperation, said Franz Wolber, shareholder of the Kwerk GmbH, on the occasion of signing the cooperation agreement and press conference in Amsterdam.

Upon request, we would be pleased  to send you our detailed quotation, if desired for other variants as well.

 



Y-STRAINERS MADE OF  PVC U, PP AND PVDF

DN 65 - DN 500



Montabaur, 15/09/2016

The recently designed Y-strainers made of PVC U, PP and PVDF, are manufactured in our specialist workshop from qualified personnel for chemistry and process engineering.
Y-strainers with the indicated nominal sizes find application in wastewater- chemical- and process engineering. The strong dirt-holding capacity offers significant advantages to the operator, compared with other versions on the market.

On request, we would be pleased to submit you a detailed quotation for the above mentioned items.





 


POT STRAINERS MADE OF PVC U, PP AND PVDF

DN 65 - DN 300



Montabaur, 12/09/2016

Our new pot strainers made of PVC U, PP and PVDF,  meet all operational requirements for use in the chemical industry. Other than the simple angle seat strainers, our new pot strainers have high dirt-holding capacities, which increases the lifetimes in plants of the chemical industry and process engineering. 

On request, we can equip in our workshop these strainers with measuring instruments, in order to control the procedural steps.

With pleasure, the Kwerk GmbH team will submit a quotation.




 

PVC TRANSPARENT BALL VALVES

d 20 - d 63 mm according to DIN standards and in INCH dimensions



Montabaur, 12/09/2016

Together with our partner, we conceive and develop PVC U transparent 2/2-way ball valves for the water technology.

The 2-way ball valve is equipped with screw connection and gluing sleeve and is on request also available with internal threads made of  PVC U grey.

Housing, inserts and union nuts are made of PVC U transparent, the valve seat of PTFE, the O-rings optionally of  EPDM or FPM and the locking lever of ABS.

The ball valve can be operated with a working pressure of max. 10 bar, at a temperature of 20°C. When using the valve, please mind always the pressure and temperature diagram for PVC U transparent.

With pleasure we will respond to appropriate inquiries.






 


LOOSE AND COLLAR FLANGES FOR PRESSURELESS APPLICATIONS

MADE OF PVC U, PVC U TRANSPARENT, PE and PP



Montabaur, 15/12/2015

On a recently designed sheet milling machine we process customized round and square plastic flanges for pressureless applications. Beyond that we produce other items according to customer specifications. The advantage of parts, milled from the solid, is obvious, because of their mechanical strength. They have a favourable price and can quickly and precisely be produced with modern CAD and CNC technology.

On request, we would be pleased to send you a quotation.
