High-performance refiner plates with SAS and VGD technologies for 1483 and 2734 series refiners, delivering consistent fiber quality and maximum plate life.
Parason Refiner Plates are engineered with advanced SAS (Small Angle Sector) and VGD (Variable Groove Design) technologies to deliver superior fiber development, energy efficiency, and extended plate life across all stock preparation refining applications.
Available in multiple configurations for both flat disc and conical refiners, our plates feature precision-cast bar patterns optimized for specific pulp grades and refining targets. The VGD technology ensures progressive fiber treatment, while SAS geometry maximizes refining intensity per sector. For broader refiner fillings options including ERP technology, see our complete range.
(12 Sectors)
Standard flat disc plate for general-purpose refining with proven bar geometry.
(24 Sectors)
Advanced flat disc with Small Angle Sectors and Variable Groove Design for superior fiber development.
(7 Sectors)
Standard conical refiner plate with optimized bar pattern for efficient deflaking and refining.
(9 Sectors)
Conical plate with Variable Groove Design and Small Angle Sector for maximum refining performance.
Progressive groove depth ensures optimal fiber treatment — aggressive initial deflaking transitioning to gentle fibrillation for superior pulp quality.
More sectors per plate means higher refining intensity, more bar crossings, and superior fiber development per revolution.
Optimized bar and groove geometry reduces specific energy consumption while maintaining target freeness and strength properties.
Premium alloy materials and precision casting ensure longer operational life, reducing downtime and replacement frequency.
CNC-machined profiles with tight dimensional tolerances and balanced sector weights for consistent refining performance.
Available for multiple disc diameters in both conical and flat disc types, with OEM replacement compatibility for all major refiner brands.
Parason manufactures SAS VGD refiner plates with:
Parason SAS VGD refiner plates are available as direct-fit replacements for flat disc and conical refiners from European, American, and Asian OEMs:
| Plate Series | Fits Refiner Type | Configuration |
|---|---|---|
| 1483 Regular | Flat disc refiners (all OEM makes) | 12 sectors, standard bar geometry |
| 1483 SAS VGD | Flat disc refiners (all OEM makes) | 24 sectors, progressive groove depth |
| 2734 Regular SC | Conical refiners (all OEM makes) | 7 sectors, standard conical pattern |
| 2734 VGD SAS SF | Conical refiners (all OEM makes) | 9 sectors, VGD + SAS combined |
Send your refiner nameplate or model number — Parason engineering will confirm the correct plate series and SAS VGD configuration for your machine.
Standard refiner plates use uniform bar geometry with fixed groove depth. Parason SAS VGD plates improve on this with two proprietary design features:
| Feature | Standard Plate | SAS VGD Plate |
|---|---|---|
| 1483 Sectors | 12 | 24 |
| 2734 Sectors | 7 | 9 |
| Bar Crossings | Standard | Higher per revolution |
| Groove Profile | Uniform depth | Progressive (deep → shallow) |
| Energy | Baseline | Lower specific energy consumption |
