Motor driven diaphragm metering pump designed for simple operations. It is especially suited to continuous dosing. 

  • 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 continuous, automatic ventilation
  • Controlled via mains ON/OFF connection
  • 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

Accessories (10)

Accessorie Product details
Injection Valve

Used for generating pressure and preventing backflow.

Back Pressure Valve

Used to generate a constant back pressure for precise dosing and/or to protect against overdosing, or for dosing accuracy with an open discharge or a positive pressure on the suction side. Used with pulsation dampeners to produce low-pulsation dosing.

Foot valve

For connection at the end of the suction line. Used to create pressure and to prevent return flow. Important: Injection valves are not intended as completely sealed units.

Float Switch

Float switches enable problem-free and flexible integration of metering pumps into automatic control loops.

Suction Assembly

For ProMinent® solenoid pumps consisting of foot valve, adjustable retaining tube with screw connection and intake line.

Suction Lance

Consisting of foot valve, retaining tube and screw connection, intake hose.

Suction and discharge pipe

for metering pumps and accessories. We recommend using the original lines to ensure the mechanical connection in case of clamping ring fittings as well as compressive strength and chemical resistance. On request, food grade version is possible.

Control Cable

Control cables enable problem-free and flexible integration of metering pumps into automatic control loops.

Relief Valve

The relief valve protects all system components against damage due to pressure overload.

Wall Mounting Bracket

With fixtures, to hold one metering pump.
