The Pneu-Flap™ Pneumatic Torque Controller is designed to provide a constant torque through the full range of motion of the pump discharge flapper valve, thereby maintaining a good material seal at all times between the pressurized conveying line and the pump screw.

Designed to be easily adjustable for the specific operating conditions, the Pneu-Flap Torque Controller minimizes component wear and improves the Fuller®-Kinyon pump performance by optimizing the flapper valve torque.

• Improved performance and higher capacity
• Reduced wear due to less blow-back through flapper valve
• Reduced overall maintenance cost
• Lower overall power consumption
• On-line adjustment of the flapper valve
• Less movement of the flapper valve
• More stable operation
• Easy to install
• Change materials and torque adjustment without shutting down
