In high-pressure pumping systems, component reliability is directly linked to operational continuity. Plungers and mechanical seals are subject to extreme mechanical stress, friction, corrosion and chemical exposure, making standard manufacturing solutions often insufficient over time.
Through advanced thermal spray coating technologies, TSS develops custom plungers and mechanical seals engineered to withstand the most demanding industrial environments. By combining precision machining with HVOF and plasma spray processes, these components are designed to deliver consistent performance in sectors such as hydraulics, petrochemicals and energy.
Thermal Spray Technology Applied to Critical Components
Thermal spray manufacturing enables the creation of highly resistant surface layers on metallic substrates such as stainless steel or tool steel. This approach allows the base material to retain its structural properties, while the coating provides enhanced protection against wear, corrosion and friction.
For plungers, coatings based on tungsten carbide or chromium carbide are applied using HVOF technology to achieve exceptional hardness and minimal porosity. For mechanical seals, ceramic coatings such as aluminium oxide-based materials are used to create smooth, low-friction surfaces that ensure optimal sealing performance even under continuous operation.
The result is a component that combines structural strength with advanced surface engineering, capable of operating reliably under high pressure and aggressive conditions.
Precision Manufacturing and Process Control
At TSS, the production of plungers and seals is managed through a fully integrated process that ensures tight tolerances and repeatable quality. Each component is engineered to meet precise dimensional requirements, often reaching tolerances in the range of microns, essential for hydraulic sealing systems.
The manufacturing workflow includes:
- precision machining and surface preparation to optimise coating adhesion
- controlled thermal spray deposition using robotic HVOF and plasma systems
- post-coating grinding and finishing to achieve exact tolerances and surface roughness
- final inspection and quality validation through advanced testing methods
This integrated approach ensures that every component meets both mechanical and functional specifications required in high-performance pump systems.
Performance in High-Pressure and Critical Environments
Custom plungers and mechanical seals manufactured with thermal spray technology are designed to operate under extreme pressures, often exceeding hundreds of bar, while maintaining dimensional stability and surface integrity over extended service cycles.
The use of carbide-based coatings significantly reduces adhesive wear and surface scoring, while ceramic sealing faces improve resistance to friction and chemical attack. This combination enables reliable sealing performance, even in applications involving aggressive fluids or continuous operation.
In real industrial conditions—such as offshore systems or chemical processing plants—these components demonstrate extended service life and reduced failure rates, contributing to greater operational reliability.
Industrial Value and Strategic Advantage
For companies operating in demanding sectors, the ability to rely on durable, high-performance components is a key competitive factor. Thermal spray manufacturing offers a strategic alternative to conventional solutions, enabling both the production of new components and the refurbishment of worn parts.
By extending component lifespan, reducing maintenance frequency and improving system efficiency, custom plungers and mechanical seals contribute directly to lower lifecycle costs and improved asset performance.
Partnering with TSS means accessing specialised expertise in thermal spray coating, precision engineering and application-specific design—ensuring that each component is tailored to real operating conditions and performance requirements.
