Pulp and Paper Market • Primary SIC Codes

– 2611 Pulp Mills• Establishments primarily engaged in manufacturing pulp from wood or

from other materials, such as rags, linters, wastepaper, and straw. Establishments engaged in integrated logging and pulp mill operations are classified according to the primary products shipped.

– 2621 Paper Mills• Establishments primarily engaged in manufacturing paper from wood

pulp and other fiber pulp, and which may also manufacture converted paper products. Establishments primarily engaged in integrated operations of producing pulp and manufacturing paper are included in this industry if primarily shipping paper or paper products.

– 2631 Paperboard Mills• Establishments primarily engaged in manufacturing paperboard,

including paperboard coated on the paperboard machine, from wood pulp and other fiber pulp; and which may also manufacture converted paperboard products.

Common Paper Mill Pump Issues

• Short Life – Seal Leakage– Run Dry

• Pumpability– Entrained Air– Varying Viscosities– Thixotropic


Primary HD Applications

• Black Liquor Soap– Kraft (Pulp) Mills– Chemical Recovery Area


Pulp Plant Flow

Black Liquor Soap and Tall Oil


Primary Applications

• Black Liquor Soap Pumping Challenges– Abrasive– Air Entrainment– Varying Viscosities– Can be shear sensitive “thixotropic”



• Paper Coatings– Coated Papers– Fine Hardwood Papers, eg. “copy paper”

• Not softwood corrugated box paper

Coating



• Paper Coatings– Clay Fillers, – Titanium Dioxide– Pigments– Binders



• Paper Coatings Kitchen


Primary HD Applications • Paper Coatings Flow

Chart



• Paper Coatings Pump Challenges– Product tends to agglomerate– Varying viscosities– Leakage– Entrained Air



• Centrifugal Pump Disadvantages– Wear due to speed– Vapor locking– Cannot handle higher viscosities– Cannot handle shear sensitive liquids



• Progressive Cavity Pump Disadvantages– Run dry damage – Long foot print


HD Advantages

• Will Handle Thin to Thick Materials• No Metal to Metal Contact for Low Wear• Low Shear• Ideal Pump for Black Liquor Soap, Paper

Coatings


HD Advantages

• Tuffseall™ Out on Test in a Black Liquor Soap Service on an HD Pump


GG Applications

• Lower Concentration Thick Black Liquor Soap and Paper Coatings– Best results with running slow: Under 250 RPM– Consider hardened parts options– Abrasive duty seal


Other GG Applications

• Sizing Agents Used Upstream of Paper Machine– Starch– Rosin

• Tall Oil in the Chemical Recovery Area


LubeTech Applications

• Numerous Equipment Lubrication Pumps– Bearings requiring forced lubrication


TechnaFlo Applications

• Paper Additive Chemicals

Paper Chemical Addition Points


TechnaFlo Applications

• Water and Wastewater Treatment Chemicals– Cooling Tower– Boiler Feed– Wastewater
