History and development

KRANZ was founded in 1906. Outstanding success has been obtained in developing stuffing boxes to be used in the high pressure service.

Our high pressure packing „type K“ was developed and patented in 1927 in connection with the introduction of various ammonia high pressure syntheses, at a pressure range up to 1000 bar/ 14503 psi

KRANZ was the first company introducing PTFE from the United States into the European compressors market in 1958. For decades we manufactured compressor components meeting successfully both sealing and life requirements in all kind of applications up to 3500 bar/ 50763 psi.

Partner for the Industry

Our Service offer:

Repair and reconditioning of Valves, packings and piston rods, even from other manufacturers.

Valves are subject to constant wear and are also frequently exposed to heavy contamination. Regular maintenance  dependent on the actual operating conditions  is therefore an absolute must.

We offer a maintenance and repair service for all valves, irrespective of their type or origin. This service includes dismantling, cleaning, rectification and any necessary replacement of individual parts. The valves are then tested to ensure that they are working perfectly, using the latest test and inspection methods.

The packing housings also wear during the course of time. The sealing surfaces in particular no longer fulfil their function and have to be reconditioned. We will repair your packings, no matter what type or make they are. The packings are disassembled, cleanded, reconditioned and if necessary completed with individual housings. After lapping the sealing surfaces, the packing is reassembled with new sealing elements and you get back a packing as good as new.
