ANDRITZ Submersible Pump Spare Parts Wear Plate

Our brand provides integrated fluid machinery solutions to industrial customers worldwide — covering component supply, system engineering, and overseas technical field support through a single coordinated channel. The product categories we serve include pumping units across multiple configurations, frequency converters and variable speed drive equipment, servo control and positioning systems, operator interface terminals and programmable automation platforms, motor control centers and switchgear assemblies, electric motors and speed-reducing gearboxes, mechanical seal assemblies and support systems, shaft coupling products in flexible and rigid designs, and gear-type power transmission units. For field engineering, we deploy our own specialists to international project sites to execute FARO 3D scanning for reverse replication, precision laser alignment of pump-driver trains, full pump commissioning and performance verification, and on-site diagnosis and corrective service for operating machinery.

ANDRITZ Wear Plate (also called a side plate, suction side liner, or casing wear liner depending on the pump configuration) is a replaceable flat or contoured plate installed inside the pump casing to protect the casing wall from direct erosion by the pumped fluid containing abrasive solids. In slurry pumps, the wear plate is typically located on the suction side of the casing, facing the impeller eye, and forms a replaceable wear surface that takes the brunt of the abrasive attack.

Some pump designs also incorporate an additional discharge-side wear plate on the casing back surface, providing a complete replaceable lining for the volute region. The wear plate is designed as a sacrificial component — its thickness provides an acceptable wear life after which it is replaced, protecting the more expensive and more difficult to replace casing casting.

Our ANDRITZ replacement wear plates are produced using FARO 3D scanning for geometry capture, CNC-machined pattern equipment, resin sand or V-process casting, and full dimensional and hardness verification before dispatch. Available in standard and high-chrome abrasion-resistant alloys.

• FARO 3D Reverse Engineering — Full surface scan captures the wear plate contour, bolt pattern, and register fit without original drawings
• High-Chrome Casting Expertise — Specialized in Ni-Hard and high-chromium white iron metallurgy for maximum abrasion resistance in slurry pump service
• Interchangeability — Each plate is dimensionally verified to match the original, ensuring bolt hole alignment and casing fit without modification
• Wear Life Consistency — Hardness tested per production lot to ensure consistent wear characteristics from replacement to replacement
• Bolt-Free Mounting Options — For large slurry pump plates, pin-and-clamp mounting eliminates bolt erosion and simplifies replacement

• Dimensional Verification — Overall plate dimensions, bolt hole positions, register diameters, and flatness checked against scan data or drawing
• Hardness Testing — Brinell hardness measured on the wear surface and on a production coupon to confirm heat treatment consistency
• Material Certification — Chemical composition analysis from spectrographic sample taken during pouring; mechanical property test results from coupon
• NDT Inspection — Dye penetrant examination of the wear surface and machined areas to detect casting defects (shrinkage, porosity, cold shuts)
• Visual & Dimensional Report — Photographic record and dimensional inspection report included with each shipment
