Stator Wear Monitoring Techniques: Ensuring Reliability in Industrial Rotating Machinery Stators are the backbone of rotating machinery—from power generators in utility plants to conveyor motors in manufacturing lines. Their performance directly impacts operational continuity, yet unexpected wear-...

Oil entrapment is a common problem in positive displacement hydraulic pumps, and direct-coupled single-screw pumps are no exception.

Industry Background and Market Demand Screw pumps are widely used in industries requiring high-viscosity fluid transfer, including oil and gas, wastewater treatment, food processing, and chemical manufacturing. Their ability to handle abrasive, viscous, and shear-sensitive fluids makes them indispensable in these sectors. However, the stator—a critical wear component—degrades over time due to friction, chemical exposure, and thermal stress.

Essential Accessories for Screw Pump Upgrades: Enhancing Performance and Reliability

When pumping high-viscosity media, adjusting the speed of a screw pump is a critical step to ensure proper operation and minimize wear. Here are some suggestions:

Industry Background and Market Demand Sludge screw pumps are critical in wastewater treatment, mining, and industrial processing, where viscous fluids with high solids content must be transported efficiently. The global demand for these pumps is rising due to stricter environmental regulations and the expansion of municipal and industrial wastewater infrastructure. Unlike centrifugal pumps, screw pumps excel in handling thick, abrasive, and non-Newtonian fluids, making them indispensable in sectors requiring reliable sludge transfer.

Industry Background and Market Demand Screw pumps are widely used in industries such as oil and gas, wastewater treatment, food processing, and chemical manufacturing due to their ability to handle viscous fluids with high efficiency. However, maintaining these pumps requires reliable, cost-effective accessories to ensure longevity and operational efficiency.

In a progressive cavity pump, the driving and driven screws rotate in opposite directions. That is, when the driving screw rotates clockwise, the driven screw rotates counterclockwise, and vice versa. This opposite rotational direction relationship is determined by the operating principle of the progressive cavity pump.
