Bild vergrößernBeta® Membrandosierpumpe

The solenoid metering pump Beta® is equipped with all setting and control functions for modern water treatment and chemical metering. As compared to its predecessor model, it features a pulse step down and step up function. This facilitates a more accurate adaptation to external signal transducers. The result is an easier and more precise adjustment of the metering to the actual requirements.

  • Capacity range 0.74 - 32 l/h, 25 - 2 bar
  • Continuous stroke length adjustment from 0-100 %

Accessories (11)

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.

Flow Meter DulcoFlow® DulcoFlow®

Operates based on the ultrasonic measurement method. Media contacting parts manufactured using chemically resistant PVDF. Therefore, aggressive media can also be measured without problem. Installed directly in the pipe of the medium being measured.
