White Iron Pump Re-Engineering and Performance Upgrade

Project Overview

KARM DESIGN was commissioned to re-engineer a volute casing, casing liner, and impeller for a process pump that was suffering from accelerated wear and reduced efficiency. The client needed a durable solution that would improve both wear life and operational performance over the original design.

Solution

Our engineers carried out a full dimensional assessment of the existing components and applied material and design enhancements during the re-engineering phase.

  • All wetted components were manufactured from high-chromium white iron, providing superior abrasion and erosion resistance.
  • Key clearances were refined to improve hydraulic efficiency and reduce recirculation losses.
  • Subtle geometric optimisations were introduced to enhance overall pump reliability and flow characteristics.

Each component was precision-machined and inspected in-house to ensure compatibility with the existing pump assembly and consistent high-quality finish.

What our clients say

“We were facing corrosion issues with key pump components after the original equipment manufacturer ceased trading. KARM DESIGN was approached to supply replacements and provide a more robust long-term solution. Their team identified alternative materials with improved corrosion resistance, offered a lead time significantly shorter than other potential suppliers, and provided a competitive cost that allowed us to secure additional spares for reduced future downtime. Since installation, the equipment has performed beyond expectations, improving reliability, extending service intervals, and lowering maintenance costs. KARM DESIGN delivered exceptional results and dependable support throughout the project.”
