What Causes Screw Pump Seal Failure? Key Factors You Shouldn’t Ignore
What Causes Screw Pump Seal Failure? Key Factors You Shouldn’t Ignore In industrial fluid handling, screw pumps are widely used for their stable flow, low pulsation, and strong ability to handle high-viscosity or particle-laden media. However, in real-world applications, one issue still shows up frequently: seal failure. From an engineering perspective, it’s fair to say that choosing the right pump is only half the job—whether the sealing system is reliable often determines how long the pump can run without trouble. So what actually causes screw pump seal failure? Here are the key factors. 1. Fluid Characteristics: The Most Overlooked Factor Many users focus on flow rate and pressure, but overlook how the fluid itself affects sealing performance. Typical risks include: High viscosity → increases friction and heat Solid particles → cause abrasion and scratches Corrosive media → attack sealing materials Crystallizing fluids → deposit around seal faces 👉 In many cases, seal failure ...
