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. INDRON® Vertical Pump Bearings Key FeaturesChoosing 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.
