Workshop services for pulping

Valmet’s bale pulpers and under-the-machine pulpers represent the most advanced pulping technology that meets the highest requirements to ensure reliable production with the optimal performance and cost-effective availability needed in stock preparation production.

Pulper rotor units, bearing units and rotors need periodic reconditioning, and for guaranteed pulper availability, spare units are needed. Valmet offers a full range of workshop services for pulpers: reconditioning services; pulper and rotor upgrades; and exchange unit services.

Workshop services for screening

Screening is essential for cleanliness, fiber quality and fiber loss. Valmet’s screening for coarse, fractionation, fine and machine screening responds to all these challenges in stock preparation production.

Workshop services offer vital maintenance solutions for the screening. Complete screen overhauls with the latest upgrades guarantee the optimal screening performance. Standard bearing unit reconditioning or exchange units are the basis for maintaining the screens. Rotors are reconditioned with standard foils or upgraded ones, depending on the target of the workshop services scope.

Valmet Oil Monitoring for stock preparation equipment

Most bearing failures occur due to insufficient lubrication. Insufficient lubrication typically arises from missing or contaminated lubricant.

The traditional indications of bearing failure are increased vibration and temperature. These can be considered lagging indicators because failures have already progressed when they arise.

Valmet offers intelligent solutions for oil monitoring. Using oil quality as the leading indicator supports a predictive maintenance approach.

 Benefits:

• Early warning of oil contamination or degradation
• Avoid expensive bearing failures and unplanned shutdowns
• Detect leakages in the lubrication system
• Warning signal about misoperation
• Remote services from Valmet (optional)

Exchange unit agreement – a powerful risk management tool

Finding a balance between risk and costs in the spare equipment inventory can be difficult. Valmet’s Exchange Unit Agreement is an alternate solution that eliminates the need to purchase your own spare equipment. The agreement ensures dedicated equipment in perfect condition is always available to the customer. Agreements are established based on each customer’s needs. Agreements are powerful risk management tools, with known annual costs.

A lighter exchange unit service is available for multiple equipment and assemblies – for example, for bearing units, adjusting assemblies or complete refiners.
