Extended Life (EL) Retrofit

The Extended Life (EL) Retrofit is aftermarket impeller and throatbush matched set designed for Warman® WRT® configured wet ends.

They are designed for less wear, less downtime and lower cost per tonne pumped.

Key Benefits

  • Targets wear hot-spots
  • Scan-based verification
  • Cost-back guarantee

Why this retrofit exists

In severe and/or off-BEP slurry, the limiting wear still happens at the interfaces and leakage paths:

  • Nose-gap / throatbush bypass wear (solids ingress at the dam area)
  • Expelling vane tip-vortex scouring at faces/clearances
  • Swirl effects across the real operating band

The EL upgrade is an engineered aftermarket solution designed for WRT® configured wet ends, optimised to improve wear performance.

What is different in a 7D matched set?

  • Impeller – severe‑duty twisted‑vane hydraulic designed to reduce wear
  • Extended shrouds – suppress expelling-vane tip vortices improving volute liner, throat bush and impeller life
  • Solids diverter throatbush to liner – reduces nose-gap solids ingress and dam-area ratholes
  • Straight, vortex-breaking vanes – stabilises inlet flow

EL Retrofit for Warman WRT Configured Wet Ends

How we prove it objectively

  1. Baseline laser scan of your existing WRT parts and volute liner.
  2. Install 7D’s EL parts.
  3. Run for the currently attained life of the WRT parts (record duty).
  4. Re-scan + 3D overlay wear maps + compare $/hour and $/tonne pumped.

Cost-back guarantee: if operating cost is not lower in the agreed trial window, 7D will take the parts back and refund the purchase price. Guarantee subject to agreed trial plan and measurement method; terms available on request.
