ProMinent – Beta Pump

The ProMinent Beta B solenoid diaphragm metering pump is designed to accurately dispense precise amounts of liquid chemicals into a system or process. It uses a solenoid-driven diaphragm to create a consistent and reliable flow, making it ideal for dosing applications in industries such as water treatment, chemical processing, and manufacturing. It offers flow rates from 0.16 to 8.45 gph (0.59 to 32 l/h) and handling pressures up to 363 psi (25 bar).

The feed rate is regulated by adjusting both stroke length and stroke frequency. Stroke length can be set from 0% to 100%, providing a 10:1 turndown ratio, while stroke frequency is adjustable in 10% increments from 10% to 100%. Optional external control is available via a standard 4-20 mA or pulse contact signal for greater operational flexibility.

Features:
Certified to NSF/ANSI 61 (acrylic or PVDF liquid ends)
50% less power consumption
Auto-degassing liquid ends are 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
Continuous 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
