Beta® Solenoid Diaphragm 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.

Benefits

• 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
