Item Number: BetaB
Our Price: Call for pricing

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

  • 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

Above capacities and suction lift refer to pumps tested on water at 115 VAC, 60 Hz, and an ambient temperature of 70°F (21°C). 
Higher specific gravity fluids will reduce suction lift. Higher viscosity fluids will reduce capacity. 
Liquid ends for highly viscous media have 10-20% less metering capacity and are not self-priming. Standard connectors are 1/2" MNPT or 5/8" hose barb. Positive suction recommended. 
* Not available with bleed valve. 
** SS versions use 1/4" female threads except models 0220, 0420, and 0232 which use 3/8" female threads. 
*** Only available in SS and Acrylic liquid ends
