Project Overview

When a mining operation in Carlisle, Pennsylvania, was faced with the high cost of rebuilding an aging competitor's submersible dewatering pump, the customer began looking for a more economical replacement option.

Working with the sales rep company EastRock Solutions, American-Marsh evaluated the application and proposed a different approach. Rather than replacing the existing submersible pump with another traditional submersible pump, the team identified that a standard American-Marsh Submersible Vertical Turbine Pump, paired with a custom cooling shroud, could provide the required performance at half the cost.

The result was a practical, outside-the-box solution that delivered reliable performance while significantly reducing project costs.

The Challenge

The existing competitor pump operated in a groundwater collection pond using a suspended installation rather than a traditional well application. The quoted rebuild cost prompted the customer to explore alternative solutions.

The application required a pump capable of meeting the system's hydraulic requirements while operating reliably in an environment where a vertical turbine pump would not typically be considered. The challenge wasn't finding another pump, it was finding a smarter way to solve the problem.

The Solution

Rather than viewing the application through the lens of a traditional submersible replacement, American-Marsh looked at the operating conditions and identified an opportunity to utilize a standard Submersible Vertical Turbine Pump.

To make the installation suitable for the application, the team incorporated a custom cooling shroud that allowed the standard pump to operate successfully in the suspended pond environment.

The selected pump was designed for 1,000 GPM at 170 feet of total dynamic head, providing the required hydraulic performance without the expense of rebuilding the existing equipment.

Results & Customer Benefits

The installation performed almost exactly as expected. During startup, the pump delivered around 950 GPM, which closely matched the design point while providing dependable operation.

What was really impressive was that the complete solution, including the custom cooling shroud, cost less than half the price of rebuilding the existing competitor's submersible pump. More importantly, the project demonstrated the value of looking beyond conventional replacement options.

Customer Benefits

• Less than 50% of the cost of rebuilding the existing pump.
• Reliable performance that closely matched the design point.
• Utilized a proven, standard American-Marsh Submersible Vertical Turbine Pump.
• Simple adaptation with a custom cooling shroud rather than a custom pump design.
• Minimized project costs while maintaining dependable operation and project deadlines.
• Demonstrated American-Marsh's willingness to evaluate each application individually rather than simply replacing equipment like-for-like.

Thinking Beyond Traditional Replacements

Not every application requires a conventional solution.

At American-Marsh, our team works with distributors, engineers, and end users to evaluate each application and identify practical, cost-effective alternatives. Sometimes the best answer isn't a custom-designed pump, it's applying proven products in innovative ways.

This mining project is a great example of how applying application knowledge, flexibility, and collaboration can help our partners reduce costs while achieving reliable, long-term performance for their mining pump applicaitons.
