Approach Flow Equipment
Fan Pump
A critical approach flow pump that delivers low-consistency stock to the headbox with stable flow and pressure, supporting better sheet profile and machine stability.
Product Introduction
The fan pump is one of the most important pumping units in the paper machine approach flow, because unstable delivery directly affects headbox performance and the sheet profile. The unit is selected according to stock flow, consistency, machine width, and system pressure requirements.
Typical Supply Scope
- Pump body, impeller, and drive arrangement
- Flow control integration and instrumentation support
- Connection with screening, deaeration, and headbox system
Application Notes
Often reviewed during paper machine upgrades where clients want more stable approach flow and improved basis weight profile behavior.
