Paul Boughton

Colfax Fluid Handling has delivered end of 2014 three Allweiler propeller pumps to a German chemical company. The pumps will move sodium sulphate.

Cordenka GmbH & Co. KG, based in Obernburg, Germany, is a leading manufacturer of technical fabrics and cords. The company also produces sodium sulphate, which is sold to the detergent and glass industries. Since the end of 2014, the company uses three additional new propeller pumps from Allweiler GmbH for these processes. 

The pumps move saturated sodium sulphate at a rate of 750 m3/h; delivery head is 3.5 m. Beside these new pumps Cordenka use since years about 100 Allweiler pumps, mainly three-screw and centrifugal pumps. Allweiler propeller pumps are used since 2013. Additional new orders are expected.
