Modification Of Water Tank On A Nilfisk SC Delta For A Food Processing Factory In Birmingham

What they needed

We were asked to upgrade an existing Nilfisk multi-pump system at a food factory in Birmingham that was struggling to keep up with demand during nightly clean-downs.

With multiple pumps running simultaneously, the system required increased water capacity and improved control to ensure consistent performance and prevent interruptions.

Problem / Requirement

  • Existing setup: Multi-pump system with an 80 litre water tank.
  • Main issues: System running out of water when all pumps were in use, causing pressure drops and inconsistent performance.
  • Site conditions: High-demand environment with all pumps operating during nightly clean-downs.
  • Usage: Intensive, regular cleaning requiring consistent flow and reliability across all pumps.

The goal was to increase system capacity and improve control so the setup could handle full demand without running dry or affecting performance.

Our Solution

  • Upgraded the system with a larger 160 litre water tank to increase available capacity.
  • Installed new level switches to maintain correct water levels and prevent both overflow and dry running.
  • Fitted new solenoids to improve control of water entering the tank and ensure reliable refill operation.
  • Installed a new thermostat to maintain stable operating conditions and protect system components.
  • Replaced feed hoses to all pumps to improve flow and ensure even water distribution across the system.

The Result

  • System now capable of handling full demand with all pumps running simultaneously.
  • Eliminated water shortages during nightly clean-down operations.
  • The site has since upgraded from a 5 pump system to a 6 pump system, and has not run out of water during clean-down since the tank upgrade.
  • Improved consistency in pressure and overall performance.
  • Reduced risk of pump damage caused by poor inlet conditions.
  • More reliable and controlled system suited to a high-demand industrial environment.
  • Long-term performance improved through increased capacity and upgraded components.
