When the impellers are new, they are the correct shape for the Stainless Steel Submersible Pump design. But this will not last. Over time, the fluid flowing on the impeller will wear down the material, thereby changing the size of the impeller. Although this is true for all fluids (even clean water), this is especially true for fluids that also contain suspended matter (such as sand, mud, sticks, and other debris).

Since the impeller blades are worn during the entire pumping process, their pumping capacity will be reduced. You will begin to notice a drop in performance in perfusion time and flow.

Solving the impeller problem is easy. You can't actually repair the impeller, but the design of the centrifugal pump makes it possible to replace the impeller. Since you may not have the luxury of waiting for the impeller to be delivered, it is best to keep them handy when needed. It doesn't happen often, but when they wear out, they can waste your time and money, so what you have on hand will reduce the time you spend on a poorly performing pump.

If your impeller wears faster than you expected, please contact us. The problem may be that the pump you are using is not designed for your needs. Just because "something" can pass through the pump does not mean that the pump is designed to handle it.

Blocking is not the only problem caused by suspended solids in the fluid. Small solids such as sand, mud, and silt (abrasives) may not clog the pump quickly, but their damage can be even more serious. Excessive wear on the impeller may indicate too much abrasive in the fluid. This will not only wear the impeller, but also damage the mechanical seal, preventing fluid from entering the engine. If the pump you use is not designed for disposal, the engine itself may be in danger.
