Pump Selection Tips
Underground miners considering a new pump should answer some questions internally before they approach manufacturers for recommendations. Tsurumi provided the following checklist to consider:
What will be pumped? Pumps have limitations. Mine water often has solids and can be corrosive. The filter perforation size on the pump indicates which particles can pass; some are up to 30 mm. A corrosive medium may require more durable materials. Tip: Attach anode blocks to the pumps to prevent corrosion.
What’s the pumping volume? The water volume that needs to be pumped is usually the factor that dictates the required pump output. Each pump covers one range and has an optimum, which is why there are so many types. Tsurumi has around 800. Tip: Choose slower pumps because they are less prone to wear.
