Motor-Driven Metering Pump alpha

Capacity range 1.0 – 30.6 l/h, 10 – 2 bar

The motor-driven metering pump alpha is the metering pump for liquid media and the optimum solution for simple applications. Robust, low-noise, chemical-resistant, with precise metering and good suction capacity.

The Cost-Effective Solution For Simple Applications In The Lower Performance Range.

Various pump types are available as a combination of 2 gears and 4 sizes of dosing head in materials PVDF and clear acrylic/PVC, enabling you to match the pump perfectly to your metering process.

Your benefits

  • Precise metering and good suction capacity by soft controlled suction and compression strokes
  • Tough plastic housing – shock-proof and chemical-resistant
  • Suitable for higher viscosity media, thanks to spring-loaded valves
  • Low-noise operation

Technical Details

  • Stroke length adjustment by changing the eccentricity on the pump drive when the pump is idle
  • Stroke length adjustment in 10% steps
  • Diaphragm deflection from the centre position
  • Soft controlled suction and compression strokes
