Pulp & Paper Mill Spares
Every disc, shaft and impeller we cast is machined to run as a direct replacement on your line, not just something that looks similar.
Bar and groove widths matched to Andritz and Parason spec at every size, 12″ up to 36″ and beyond. Drop-in fit, no on-site rework.
Every TDR, DDR and SDR plate is cast in high-chrome CA40 grade, holding its bar pattern and edge through continuous refining duty.
Refiner discs, turbo and pulper impellers, splined shafts, disc holders, pulper screens and centrifugal pumps, all off one production line.
Sleeves, splined shafts and disc holders finished to running tolerance, not just cast and shipped.
Non-standard bar and groove widths cut to match your refiner's duty, not squeezed into a catalog size.
Manufactured with tight dimensional tolerances for perfect fit and balance.
Premium alloy composition for longer service life and reduced replacement frequency.
Improves fiber quality while reducing energy consumption.
Controlled casting and heat treatment for uniform hardness across the entire disc.
Defect-free castings with minimal porosity and excellent metallurgical integrity.
Disc plates produced to match OEM specifications or customer-specific designs.
Designed for efficient refining and improved pulp quality.
Premium quality at cost-effective prices.
Quick production and dispatch to minimize customer downtime.
From pattern making to machining and inspection, ensuring complete quality control.
Chemical composition, hardness, dimensional, and dynamic balance checks before dispatch.
Assistance with disc selection, installation, and application optimization.
