DFD Thick Stock Pumping System

This system represents the most advanced heavy stock pumping system on the market. It exceeds the performance of all other types of stock pumping technologies in terms of higher stock consistencies, water dilution requirements, air removal requirements, non-impingement of pulp fibers, and reduced maintenance. The DFD System has all the advantages of both centrifugal pumps and positive displacement pumps with none of the disadvantages. The DFD System replaces medium consistency pumping systems based on centrifugal pump technology and high density pumping systems based on positive displacement pump technology.

• Pumps 8% - 18% consistency stock
• Changes pulp rheology to reduce apparent viscosity by 90%
• Low maintenance requirements

• Low life cycle costs

• Able to run dry for extended periods
• No air removal required
• No water dilution required
• Eliminates pulp bridging problems
• Pulsation-free laminar flow
• No impingement of pulp fibers
• No close tolerances or clearances - passes tramp solids to 3" OD or 6" long

Detailed information on the DFD system is now available on our website.
