Which outcome occurs when a progressive cavity pump stator elastomer degrades due to incompatible fluid?

💡 Explanation

When a stator elastomer degrades, its sealing ability diminishes because the elastomer swells or cracks, thus increasing internal leakage and decreasing the volumetric efficiency and flow of the pump. Therefore, reduced flow is the result, rather than increased motor load, fluid temperature, or drive shaft rupture which require other modes of failure.
