flexinox™

Corrosion-resistant gear pumps for chemical processes

MAAG flexinox™ pumps are corrosion-resistant conveying units; they satisfy the stringent quality requirements of today’s chemical processing industry and their three-piece configuration facilitates maintenance and replacement of internal parts, such as gears and bearings. They can be heated either electrically or with fluid. Thanks to the extensive range of components and materials available, MAAG gear pumps can be configured to suit customers specific requirements and therefore, are far superior to standard pumps in terms of performance and reliability.

 

Quick cleaning kit

MAAG´s FQ – ‘quick cleaning’ version has been released for the production facilities with a constant need to clean and wash the transfer line at the end of each production batch, different colours, different additives etc. The pump can be disassembled at the quickest without needing to dismantle the drive shaft from the drive motor and the seal.

This feature can be applied also on the existing pump series by using the FQ kit or the pump can be selected as a FQ model itself.

 

The FQ can change the production and maintenance style without compromising on the desired operating characteristics. It provides high flexibility and functionality with easy maintenance and part replacement possibilities.
