Pump + Valve Construction

We boost your perfomance

With decades of experience, S+C is a technical pioneer in high quality stainless steel cast components in the field of pump and valve construction. Our production processes range from vertical and horizontal spinning to static sand casting all the way through to precision casting.

The S+C range of materials covers wear-, oxidisation- and acid-resistant materials as well as high-alloy materials such as nickel-based alloys and duplex materials. Our wide range of different stainless steels provides the optimal solution for your area of application.

Whenever pumps, compressors and valves need to meet the highest demands of mechanical, thermal or corrosive stresses, we work alongside you to satisfy these requirements.

Components are delivered both rough machined and finish machined and ready to use, depending on the customer‘ s request.

Safeguarding Movement – Shafts Made from MÄRKER® Special Steels

Safety, reliability and longevity paired with the highest level of economic efficiency are the requirements that pumping plant components have to fulfill.

Schmidt + Clemens is taking on this challenge, producing both rough-turned and ready-to-install pump shafts from high-performance special steels in a modern production facility.

Pump shafts are the core elements of a pumping plant and are hence substantially responsible for fulfilling the above requirements. Resistance to aggressive media, very low shaft deflection, smooth running and the capacity to withstand load changes are qualities that ensure a long working life for a pump system and safeguard "movement".

High-Performance Special Steel Components

When it comes to pumps for heavy-duty industrial applications, shafts and pump blocks in special steel are the ideal solution. They combine safety, reliability and long service life with the highest degree of cost effectiveness. S+C is taking on the diversity of challenges in materials handling and fluid technology by employing modern manufacturing technology to produce rough-turned and ready-to-install shafts or cubic components from high-strength and corrosion-resistant special steels: forged, rolled, hardened and tempered, solution annealed or hardened.

The S+C Portfolio

Cast products manufactured by spinning, moulding or precision casting processes are used in the field of pump and plant construction. Shaft protection sleeves, split and seat rings, protective sleeves, pump housings, valve housings, impellers and guide wheels are manufactured using materials that are highly resistant against wear and corrosion.
