Product Specifications

Technical details and manufacturing context for Metering Pump or Valve

Definition
A metering pump or valve is a critical component within filling systems that precisely controls and measures the flow of liquids or semi-liquids during the filling process. It ensures accurate volume dispensing by regulating flow rates through mechanical displacement or controlled valve operation, maintaining consistent fill levels across production batches.
Working Principle
Operates through either positive displacement (pump) or controlled orifice (valve) mechanisms. Metering pumps use pistons, diaphragms, or gears to displace exact volumes per cycle, while metering valves regulate flow through precisely controlled openings. Both types integrate with control systems to adjust flow rates based on feedback from sensors monitoring fill levels.
