Beta b Metering Pump

Beta b Metering Pump

Energy efficient and NSF approved

The ProMinent® Beta® is a microprocessor-based diaphragm solenoid metering pump capable of flows from 0.16 to 8.45 gph (0.59 to 32 l/h) and pressures to 363 psi (25 bar).

Feed rate is determined by stroke length and stroke frequency. Stroke length is adjusted from 0% to 100% with a 10:1 turndown. Stroke frequency is adjusted in 10% increments from 10-100. (Optional) External control via a standard 4-20 mA or pulse contact signal.


  • Certified to NSF/ANSI 61 (acrylic or PVDF liquid ends)

  • 50% less power consumption

  • Auto-degassing liquid ends ideal for off-gassing chemicals such as bleach

  • Capable of handling up to 3000 cps of viscous media such as polymers

  • Integral bleed valve eliminates priming issues

  • Continual monitoring of chemical supply with optional dual stage level switch

  • Adjustable stroke length and stroke frequency

  • Fault and pacing relays optional

  • Standard external control via potential-free contacts with pulse step-up and step-down to adapt to existing signal transducers of 64:1 to 1:64

  • (Optional) External control via standard 4-20 mA and potential-free contacts with pulse step-up and step-down of 32:1 to 1:32
