INDRON® vertical pump bearings are engineered using PREM high-performance polymer composite materials, specifically designed for water-lubricated pumps in industrial, marine, and municipal applications. With low friction, high load capacity, and superior wear resistance, our bearings are ideal for vertical pumps, axial flow pumps, and mixed-flow pumps, ensuring reliable performance in demanding environments such as power plants, seawater desalination, and wastewater treatment.
Choosing the right vertical pump bearing is critical for long-term efficiency and reduced maintenance costs. Yanlong’s innovative PREM polymer composite bearings provide the following advantages:
Advanced PREM Material Technology: A next-generation polymer composite with high compressive strength and excellent durability.
Superior Load-Bearing Capacity: Dynamic surface pressure ≥12 MPa, ideal for high-load, high-speed pump applications.
Self-Lubricating & Water-Lubricated Design: Eliminates external lubrication, ensuring eco-friendly operation.
Dry Start Capability: Unlike traditional bearings, PREM bearings support short-term dry running up to 90 seconds, ideal for intermittent lubrication conditions.
Low Friction & Enhanced Lubrication: A unique split-groove design promotes fluid film formation at low speeds, reducing startup torque and dynamic-static friction.
Corrosion & Chemical Resistance: Withstands extreme environments, including seawater, acidic fluids (pH 5–10), and industrial process chemicals.
Longer Service Life: Outperforms traditional rubber and metal bearings, delivering twice the wear resistance in high-sediment conditions.
Lightweight & Easy Installation: Lower density than metal bearings, reducing weight and simplifying maintenance.
