The ProMinent® alpha is a metering pump designed for simple operations. It is especially suited to continuous dosing.
Advantages
- High suction capacity, smooth dosing stroke and constantly accurate dosing
- Robust bodywork: Strong shaded pole motor with gear, shock-resistant and chemical resistant housing of glass fibre reinforced plastics, controlled eccentric for stroke agitation
- Constant operation event with outgasing media possible thanks to combined ventilation valve with integrated fine ventilation screw for continuous, automatic ventilation at full operation pressure
- Good adjustment to precise use by 4 different gear reductions and liquid ends in 3 sizes and 2 materials
Features
- Capacity range 0.5 - 21 l/h, 10 - 4 bar
- Adjustment of dosing capacity via stroke length adjustment in 10% steps from 0 to 100%
- Stroke length adjustment via eccentricity adjustments
- Diaphragm control from middle run
- Coercive control of suction and discharge strokes
- Smooth, sinusoidal stroke run for suction and dosing stroke
- Constant stroke frequency
- Liquid end in PP or Acrylic/PVC
- Liquid end with double ball-valve on suction and pressure sides
- Spring-loaded valves for highly viscous media
- Patented coarse/fine ventilation for continous, automatic ventilation
- Controlled via mains ON/OFF connection
