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.

  • Adjustable stroke length and stroke frequency
  • Fault and pacing relays optional
  • External control via adjustable pulse contact signal 1:32-32:1

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
