What Parameters Need to Be Confirmed When Selecting a Ceramic Slurry Pump for Highly Abrasive Slurries?
Highly abrasive slurries continuously scour the impeller, casing, liners, and other wetted parts. When selecting a ceramic slurry pump, in addition to flow rate and head, it is also necessary to confirm the sources of wear and impact conditions.
First, the particles should be confirmed. It is essential to understand the main composition, maximum particle size, hardness, shape, and whether the slurry contains sharp or oversized foreign debris. The harder the particles, the higher the wear risk typically is; however, larger particle sizes or strong impact forces may also impose different requirements on the ceramic components.
Second, the slurry concentration and density should be confirmed. As solid content increases, the pump's power demand, pipeline resistance, and wetted part wear patterns will all change. During selection, normal operating conditions and the potential maximum concentration should be provided, rather than sizing based solely on clean water conditions.
The pump's operating point should also be confirmed. Long-term low-flow operation, pipeline blockages, improper valve throttling, or fluctuations in system resistance can all lead to localized erosion, vibration, and uneven component wear. The actual performance of ceramic materials is influenced not only by the material itself, but also by pump model selection, rotational speed, and operating practices.
It is recommended to provide wear photos, operating hours, and failure locations of the previous pump's impeller, casing, or liners. With this information, it is possible to more accurately determine whether it is necessary to adjust materials, optimize the operating point, or improve pipeline and installation conditions.
