Engineered Materials, Proven Underwater
Selected by duty
In use, materials do the real work. Cycles, contamination, and pressure shifts concentrate at contact points and along routed air paths, where wear and handling loads accumulate.
Every duty demands its own material. Polyamides, acetals, polyurethanes: family, base, and filler, all selected for constant immersion.
We specify raw materials, down to dedicated formulations, and source them from a closed set of established international producers.
Function defines the specification. Material follows.

Ageing comes first
Duty-Grade Build starts at the raw material.
Immersion works slowly. It shifts friction, sealing contact, and fit.
Resistance is read on the datasheet, then proven in-house, from tensile and impact benches to saturation tanks, where hydrolysis campaigns run up to twelve months.
For contaminated waters, compounds are engineered against chemical, biological, and hydrocarbon exposure.
Decades of underwater service stand behind the polymers.


Molded. Machined. Verified.
Control follows the material through every stage: incoming lot, molded or machined part, sub-assembly, complete device. Stainless steel: salt resistance at acceptance. Precision-drawn brass: dimensions on the CNC lines. Sub-assemblies: function at the bench. Complete devices: function again, before release.
What leaves the line is ready for the build.
