dun­ze super pres­sure technologies

We devel­op and man­u­fac­ture innov­at­ive high-pres­sure com­pon­ents and sys­tems since 1976.
Due to the rel­at­ively small mar­ket volume, there are quite few com­pan­ies in the world who are con­cerned with high-pres­sure tech­no­logy, and still few­er who devel­op cre­at­ive and innov­at­ive components.

We have developed and man­u­fac­tured the pro­to­types or com­pon­ents for almost all new high-pres­sure sys­tems. In 1985, we were the first com­pany in the world to pro­duce intens­i­fi­er with a large dis­place­ment for hydro­form­ing tech­no­logy. Even today, our hydro­form­ing check valves are world stand­ard. We are the world lead­er in valves and fit­tings. We were the first com­pany in the world to intro­duce 1.4542 (17–4‑PH) as a stand­ard mater­i­al for fit­tings and valves. Like­wise, our 120° fit­ting which is a big increase in qual­ity com­pared to the 60° fit­ting. Our product range cov­ers almost all com­pon­ents needed for the con­struc­tion of small and medi­um-sized high-pres­sure plants.

We have a focus in the man­u­fac­ture of dur­able com­pon­ents for high-pres­sure machinery, e.g. Iso­stat­ic presses, high-pres­sure test stands, pas­teur­iz­a­tion and homo­gen­iz­a­tion plants, burst­ing pres­sure test stands and cus­tom­er-spe­cif­ic high-pres­sure plants set.
Our auto­frettage sys­tems have been run­ning at oper­at­ing pres­sures up to 16,000 bars for dec­ades. As part of this activ­ity, a vari­ety of devices have been developed that are tailored to the spe­cif­ic needs of this technology.

As a ser­vice we offer pres­sure test for our cus­tom­ers, auto­frettage parts and carry out burst­ing tests. Since we are very reas­on­ably priced in this area, this is often an altern­at­ive to the pro­cure­ment of own equip­ment.
We attach great import­ance to the oper­a­tion­al safety of our com­pon­ents and sys­tems. There­fore, we ask for spe­cial atten­tion to our safety recommendations.
