How to benefit from Expanite® surface hardening & heat treatment solutions in the
Pumps industry
Surface Hardening & Heat treatment in the Pumps Industry
The Expanite® surface hardening process ensure that your products meet all the demanding requirements of the Pumps industry where the main problems always have been wear, erosion, cavitation, galling and corrosion. Valves and pumps exposed to harsh environments require enhancement to prolong the lifetime of their parts. Surface hardening plays a significant role in protecting the components from wear driven e.g. by abrasion elements in fluids or cavitation, galling especially on contact areas in movement relative to each other and corrosion when exposed to aggressive media.
Independent of the operation area of pumps – oil & gas, food & beverage, pharma & chemical, power plants or general industry applications e.g. hydrogen storage and transport -, process safety has a top priority, hence placing high demands for the equipment in usage. At Expanite we understand that downtime means lost revenue and take pride in offering the fastest lead time in the industry at an extremely competitive price level.
Expanite heat treatment is relevant where wear, corrosion, galling or premature component failure create commercial risk — and where stainless steel or other high-value materials need to perform for longer.
Challenges in the Pumps Industry
Pump components can face constant wear, abrasive media, friction and corrosion — often leading to reduced efficiency, leakage, maintenance and unplanned downtime. Expanite helps extend the lifetime of critical pump parts while preserving the benefits of stainless steel.

Increasing Lifetime
When it comes to conveying abrasive media surface hardening of the affected pump rotors and housings increases wear resistance and therewith lifetime of the pump in service. For some pump types like twin screw pumps hardening of the stainless steel surface is essential to reduce the risk of galling during the start-up phase and while maintaining or even increasing the corrosion resistance the Expanite technology is well suited and meanwhile widely spread e.g. for food & beverage applications.
Applying the Expanite hardening will guarantee you the most ideal heat treatment of your products preventing galling and thereby increasing the lifetime of your components.
