alpha c Diaphragm Metering Pumps

The ProMinent® alpha c 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
Automatic ventilation at full operation pressure with outgasing media possible thanks to combined ventilation valve with integrated ventilation screw
Good adjustment to precise use by 4 different gear reductions and liquid ends in 3 sizes and 2 materials

Features

Capacity range 1,0 - 30,6 l/h, 10 - 2 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, PVDF or Acrylic/PVC
Liquid end with double ball-valve on suction and pressure sides
Spring-loaded valves for highly viscous media
fine ventilation for continous, automatic ventilation
Controlled via mains ON/OFF connection
