A broad range of products, including mechanical seals, rotary unions, swivel joints, packing cords, oil seals and many other sealing elements for pumps, stirrers, mixers, agitators and valves. This range of rotary-motion seals is generally designed for temperatures from -50 to +220°C.
These values are approximate and may be influenced by other factors. We will be happy to consult with our expert to make sure you make the right choice.
We offer a complete range of mechanical seals for pumps from a variety of manufacturers such as Allweiler, Grundfos and many more.
We supply rotary bushings that have a cutting-edge design and are manufactured using the latest manufacturing technologies.
The cutter is used for precise, residue-free cutting of packing rings directly from the packing cord spool without the need to calculate the circumference of the packing.
The set of 21 extractors is used to remove old packing cords from sealing chambers and grooves.
Articulated joints are used to transport different types of material between two moving or rotating parts.
Carbon rings for rotary joints, carbon metal-saturated bearings for pumps, segmented seal rings for compressors, graphite vanes for pumps.
Injection compound for sealing pumps, agitators and valves. The unique combination of fibers and lubricants allows for virtually drip-free sealing.
We can supply bearings as sets for pumps to your specification. Peripheral speed up to 40 m/s and pressure 15 to 20 bar.
In our offer you will find a very wide range of materials and dimensions of bearings according to DIN, ISO, BSI, ASTM, CSN and other standards.

Expanded PTFE fibre with mineral fillers and inert lubricant. Suitable for highly concentrated chemicals.
Expanded PTFE fibre with mineral fillers and inert lubricant. Silicone core. Suitable for the food industry.
Fibre braided from strips of pure non-synthetic PTFE. Due to the impermeability of volatile substances and gases, it is wrapped with a layer of pure PTFE strips.
Yarn from pure PAN fibre type "preox" without binders. Impregnation with graphite dispersion with active corrosion and oxidation inhibitor.
DuPont NOMEX fibre impregnated with PTFE dispersion, lubricated with non-fluid mineral oil. Does not heat up, remains soft and flexible.
Yarn made of synthetic Novoloid fibre, impregnated with PTFE. Very pliable, easy to install in the stuffing box.
Yarn made of acrylic fibre impregnated with PTFE dispersion. Contains silicone lubricant. Excellent durability and low anti-wear.
Glass microfibre yarn without binders. Impregnation with graphite dispersion with active corrosion and oxidation inhibitor improves frictional properties.
Expanded PTFE fibre with mineral fillers and inert lubricant. Viton core. Suitable for the food industry.
Rotary machinery (especially pumps, mixers, compressors, etc.) places extreme demands on sealing elements, particularly compared with static flange applications. Seals must remain functional while the shaft rotates at high speed and is subject to unwanted axial vibrations. These extreme conditions can be further compounded by the chemical properties of the medium, machine runout or improper operation.
We can help you choose the right sealing element based on the machine type, operating temperature and pressure.
For information on sealing static pipe joints, see the flange gaskets section. The valve and damper seals category covers valves and dampers.
A mechanical seal is a highly efficient type of seal in terms of the overall economic and environmental impact of operation. It provides leak-free sealing and works by combining two factors - creating a pressure gradient through precise design and machining of the sliding faces. Gland packing is inserted into the stuffing box and then compressed by the gland. The choice of the right sealing method depends on the requirements we place on the rotating machine.
When choosing gland packing, it is necessary to take into account the operating temperature, pressure, shaft peripheral speed, the pH of the medium and the type of motion. The materials differ in their properties, temperature and chemical resistance, and suitability for specific operating conditions. POWERpack graphite gland packing is designed for a wide range of operating temperatures. Selected PTFE gland packing is also suitable for the food and pharmaceutical industries.
Oil seals, also known as rotary shaft seals, seal the space between a rotating shaft and a stationary part of the equipment. They help prevent lubricant or medium from leaking out while also protecting the sealed space from the ingress of contaminants.
We supply standard and high-pressure oil seals in accordance with DIN, ISO, BSI, ASTM and ČSN standards. High-pressure oil seals are designed for operating pressures of 15 to 20 bar and peripheral speeds of up to 40 m/s.
Yes. For gland packing, we manufacture pre-compressed packing rings to the required dimensions. Seals can also be supplied in non-standard sizes to meet specific requirements.
