What we supply

Sealing solutions

A seal is the cheapest part in an assembly and the most common reason it stops. So we select by operating conditions, not by visual similarity.

Select a seal All capabilities

Seal selection starts with the operating conditions: medium, temperature, pressure, speed and the geometry of the housing. The same size in a different compound behaves differently, so the applicability of any substitution is agreed with the customer before ordering.

What it solves

The seal fails before its expected service life.
Only the size is known, not the compound or the design.
The imported brand is unavailable and an equivalent for the same medium is needed.
A food-grade or explosion-protection approval is needed and the documents are unclear.

What we supply

Mechanical seals: single, double and cartridge
Rotary and reciprocating lip seals
O-rings in a range of elastomers
Gland packings: graphite, PTFE, aramid, combined
Gaskets for flanged and static joints

Input data we work with

Seal designation or dimensions
Process medium and its concentration
Operating and peak temperature
Operating and test pressure
Shaft diameter and rotational speed
Approval requirements: food grade, explosion protection, certification

How selection works

We match medium and temperature against the chemical resistance of the compound.
We check the velocity at the sealing face and the permissible pressure.
We verify the housing geometry and the chamber type.
If data is missing we state exactly what to measure on site.

Matching sheet

Parameter	Original	Proposed	Assessment
Type	Metal-cased lip seal	Metal-cased lip seal	match
Size	88 × 110 × 12	88 × 110 × 12	match
Compound	FKM	FKM	match
Temperature	−20…+200 °C	−15…+200 °C	5 °C lower
Dust lip	yes	yes	match
Documents	data sheet	material certificate	different format

Example format. The set of parameters depends on the seal type and is agreed before ordering.

Parameter alignment

The face-pair and secondary seal materials are fixed in writing.
Differences from the original are stated — temperature, compound, design.
Certification requirements are entered in the specification before ordering.

Pre-shipment checks

Designation, dimensions and compound are checked against the order.
Batch marking and elastomer shelf life are checked.
Packaging protecting against light and deformation is checked.

Documents

Supply contract and specification
Invoice and delivery documents
Material certificate where the order provides for one

Risks we remove

A repeat failure: removed by selecting on conditions, not on size alone.
Material incompatibility with the medium: checked before ordering.

Who it suits

Pump and compressor operations
Maintenance services replacing seals regularly
Plants with aggressive and high-temperature media

Stages of work

Operating conditions

We collect medium, temperature, pressure, speed and geometry.

Questions and answers

A seal fails every two months. Can you help?

We start with the cause, not the replacement. Early wear usually means an unsuitable compound, shaft misalignment, dry running, wrong chamber geometry or the wrong seal type for the duty. We review the input data and propose a solution rather than an identical part.

Can you match an equivalent to an imported brand?

We match by size, compound and duty parameters at manufacturers working to international standards. Conformity is confirmed by the specification; a material certificate is provided where the order provides for one.

We need seals for food production.

We work with food-grade approved materials. Certification requirements are entered in the specification before the order is placed — that is what makes them verifiable on acceptance.

Do seals require documents on import?

General-purpose rubber seals and gaskets as a standalone product usually fall outside the technical regulations on machinery, low-voltage equipment and electromagnetic compatibility. The exceptions matter: Ex components under TR CU 012/2011 are subject to mandatory certification, and elements subject to pressure above 0.05 MPa are assessed under TR CU 032/2013. There is no universal answer — the conclusion follows from the customs code, the purpose and the operating conditions.
