When a UK aluminium ingot provider started experiencing repeated pump failures in its casting pit, the difficulty wasn’t simply inconvenient—it was operationally vital. The offender? Exceptionally excessive course of water temperatures that exceeded the boundaries of ordinary submersible pump designs. To handle the problem, the corporate turned to Wildon UK, who partnered with KSB to ship a tailor-made, high-performance answer.
Understanding the problem
The casting course of required the return of cooling water from the pit, the place temperatures repeatedly reached 80°C and sometimes peaked at 87°C. Most submersible pumps are designed for a most of 40°C, and even enhanced fashions with cooling jackets have been failing inside months as a result of thermal stress and motor overheating.
Complicating issues additional, the location’s deep moist properly chamber supplied restricted house, requiring a pump that may very well be exactly built-in into the present infrastructure—with out counting on the pumped liquid to chill the motor.
A collaborative engineering method
Wildon UK and KSB labored intently to develop a custom-engineered pumping system that might meet the location’s distinctive calls for. The answer included:
• A hydraulic design able to absorbing 36 kW of load
• Outsized 70 kW motors, chosen to scale back inner warmth era fairly than enhance energy
• Full-scale mock-up testing to make sure a seamless match throughout set up
This method allowed the pumps to function reliably in fluid temperatures greater than twice the business norm—an unusual achievement in submersible pump functions.
Confirmed efficiency
Since set up, the system has delivered constant, dependable efficiency. There have been no failures associated to high-temperature course of liquid, and the one interruptions have been as a result of exterior components unrelated to the pump design.
This challenge highlights the worth of tailor-made engineering and shut collaboration in overcoming advanced industrial challenges. For Wildon UK and KSB, it’s a powerful instance of how considerate design and execution can ship long-term reliability—even below excessive situations.
