Retrofitting Salvatore Robuschi Pumps with Cartridge Seals, A Reliable Upgrade from Single Spring Seals

Engineers across the UK are seeing strong results as we retrofit Salvatore Robuschi centrifugal pumps with upgraded mechanical cartridge seals, replacing outdated single spring seals that fail too often in harsh environments.

Why Replace Single Spring Seals?

Salvatore Robuschi pumps, especially the RB and RG series, are often fitted with single spring mechanical seals. While common, these legacy seals struggle in conditions such as:

• Wastewater and sludge-heavy systems
• Food or chemical processing with high solids content
• Unstable pressure conditions

Over time, engineers reported issues like:

• Spring fatigue and misalignment
• Clogging due to solids buildup
• Frequent downtime and emergency repairs

The Acumen Retrofit Cartridge Seal

We engineered a drop-in cartridge seal retrofit to directly replace the single spring seals in Salvatore Robuschi pumps, with no housing modification needed. Features include:

• Fully enclosed springs for clog-free performance
• Balanced design for pressurised and abrasive duties
• Fast installation, typically under 1 hour

Real-World Results

Across multiple sites, we've seen:

• 3× increase in seal life
• 60% reduction in maintenance time
• Fewer breakdowns, less operator intervention

Which Pumps Are Compatible?

We can retrofit seals on most models from the Salvatore Robuschi range, including:

• RB Series (horizontal centrifugal)
• RG Series (open impeller)
• RD Series (vortex)

Upgrade with Confidence

If you're currently running Salvatore Robuschi pumps with traditional seals, this is an easy win, no redesign, no extra pipework, just a better seal that works.
