Medium Consistency Pump Discharge
Medium consistency pumping (dry solid content between 8-18%) and chemical mixing systems are the most important stock transfer
equipment in the modern oxygen delignification and bleaching processes, with recycled fiber and in mechanical pulp lines. These valves can
be used in two distinct ways: with variable speed pumps, the valve is run at full 90 degrees open, and with static head pumps, the valve needs
to be throttled.
Restrictions in the flow path can discourage appropriate process flow and cause decreases in throughput. Additionally, high vibration can
cause serious damage to piping and supporting structures around the stock pumps, creating production delays and safety issues.
