Hole Baskets

Parason hole screen baskets are highly sophisticated and manufactured in modern drilling workshops using the best available manufacturing technology. Due to optimized pitch design, we can achieve the highest open screen areas.


Parason hole screen baskets are ideal for use in stock preparation, broke system, pulp mill, and approach flow screening, for Parason screens and for all current machines and associated rotor combination of other suppliers.

Open Area Calculation

Slotted Baskets

Constant advances in our manufacturing methods yield the highest precision in different hole designs and roundness of the screen baskets. Each screen goes through a hard-chrome process for wear resistance quality which increases basket life.

As a leader in stock preparation equipment manufacturing, Parason has been developing profiled wedge bar baskets for the last few decades. Parason baskets efficiently remove dirt, specks & stickies to improve properties like cleanliness, strength, brightness, whiteness, and printability of paper.


Parason screen baskets are developed for use in stock preparation, broke system, pulp mill, and approach flow screening for Parason screens and for all existing non Parason screens and associated rotor combinations of other manufacturers.

Continuous improvement in our manufacturing methods yields the highest precision in different Slotted designs and roundness of the screen baskets. Each screen goes through a hard-chrome process to improve wear resistance property for a better life.

Application Based Wedge Bar Designs

Parason has developed different wedge wires considering a wide range of screen basket applications as per:

  • Open area requirement
  • Slot size
  • Strength
  • Fiber length

TF rotor design screen basket

TF rotor design – Technical features

  • Rotor designed for high consistency
  • Better pulp fluidization
  • Higher operation consistency
  • Reduces thickening factor
  • Eliminates stringing/fiber hang-ups


  • Increased capacity and runnability
  • Optimized foils number and position
  • Better pulse distribution over the cylinder surface
  • Helps to push pulp towards the reject chamber
  • Helps to handle change in consistency along with the surface screening
  • Handles higher consistency

It makes a lot of sense that a refiner disc should have uniform wear properties. Normally the variation in the wear of the refiner plates may be wavy, serrated, or flat type.

Step Rotor

  • Suitable for operation with large flat-shaped contaminants
  • Adjustable speed to suit a wide range of requirements
  • Special design features avoid string formation
  • Hard faced edges
  • Computerized dynamically balanced rotor

Solution Based On Operational parameters

  • Feed consistency
  • Volumetric reject rate
  • Rotor tip speed and rotor frequency
  • Passing velocity
  • Furnish parameters Like Temperature and PH
  • Reject thickening
  • Power consumption

Parason Inflow – Centripetal Baskets

Your benefits

  • Large, open screening surface
  • High sticky removal efficiency
  • Less energy consumption
  • High stability by welded profile bars
  • Suitable for all centripetal screening machines

Advanced rotor and screen basket design and technology

  • High screening efficiency
  • Trouble-free operation
  • Modular design
  • Low energy consumption
  • Low maintenance costs

The wavy & serrated wear causes maximum fiber damage and multiple disadvantages of high power consumption, increased cost per tonne, load variations, etc. PARASON has innovated the concept of `ERP’ that is Edge Retention Property. During strenuous refining conditions, the ‘ERP’ plate has flat wear.

Casting is done by using the latest technology to provide the best condition for the alloys in temperature, time, melting technique to determine the best suitable alloy. Due consideration to properties of erosion, corrosion, wear resistance of refiner plates is taken care of.

Re-Chrome Plating Of Screen Baskets

Extend the lifetime of your screen basket with our re-chroming and repair services. Rebuilding your existing rotors provides substantial cost-saving benefits as well as the possibility of upgrading older OEM rotors to newer more productive and energy-efficient designs for today’s demanding screening applications. PARASON also offers screen bearing assembly and housing rebuilds.

Screen rebuilds and upgrades are available for virtually all OEM makes and models.

To regain profile geometry

Due to operational wear in screening, the heads of profile bars frequently wear out. Rebuilding the chrome layer ensures constantly high screening quality.

PARASON team is specially trained in the analysis of screen baskets so as to be able to determine whether re-chroming is necessary. If so, the old chrome layer of the screen basket is completely removed. It is especially ensured that there is no change in the geometry of the profile head comes. The slot width of the screen basket also remains unchanged.

Chrome is one of the materials that are least susceptible to wear and can also be applied repeatedly. This makes re-chroming the most economical alternative for wear prevention in the case of screen baskets. Re-chroming is provided for the entire screen basket portfolio from PARASON and for those of other manufacturers. The service is also specifically available for hole screen baskets.
