Can a progressive cavity pump operate without feed material without being damaged?

A progressive cavity pump requires feed material to operate effectively and safely. When these pumps run without liquid or material, it can lead to significant problems. The absence of feed material means that there is no lubrication or cooling for the rotor and stator. This lack of lubrication can result in excessive friction, leading to wear and tear or even catastrophic failure of the pump components. Therefore, it is essential for the pump to have feed material during operation to prevent damage and ensure optimal performance. Hence, it cannot run without being damaged.
