PISTONS AND SHAFTS

We can produce different shapes and sizes. It is produced from ceramic materials: aluminium oxide, 95% Al₂O₃; 99,7% Al₂O₃ or from ziriconium oxide ZrO₂ + Y₂O₃; We can achieve surface quality up to Ra ≤ 0,2 μm.

BIG PLUNGERS

We are producing plungers with big diameters and different lengths from ceramic materials: aluminium oxide, 95% Al2O3; 99,7% Al₂O₃ or from ziriconium oxide, ZrO₂ + Y₂O₃, with very fi ne quality surface up to Ra ≤ 0,2 μm.

All plungers can be made in combination with metal. We have our own method to connect metal to ceramics, but we can also produce according to the customers drawing. Metal quality is stainless steel or it can be according to customers request.

According to the drawing or samples from customer we can produce all kind of axial bearing with very fi nely treated surface up to Ra ≤ 0,2 μm. Material can be: aluminium oxide, 95% A₂O₃; 99,7% Al₂O₃; ziriconium oxide, ZrO₂ + Y2O3 or ZrO₂ + MgO;

With our production technology, we can produce very demanding sets of cylinders and plungers or ceramic pumps, with high level of outside and inside surface quality and very small tolerances.

The production of axial bearings with big dimensions according to customers request. The material is based on ceramics aluminium oxide, Al₂O₃ and ziriconium oxide, ZrO₂.

BALLS AND VALVE SEATS

Balls and valve seats are made from ceramic material aluminium oxide, 99,7 % Al₂O3 or from zirconium oxide, ZrO₂ + Y₂O₃. Surface treatement meets high demands in valve industry.

For very aggresive media, we produce ball valves, valve seats, plungers, shafts and sticks from ceramic material zirconium oxide ZrO₂ + Y₂O₃. High degree of surface treatement suits very strict standards, that apply to this kind of products.
