Beta/4 Metering Pump for PAA

The ProMinent Beta/4 is a microprocessor-controlled solenoid diaphragm metering pump supplied by BioSafe Systems for precise PAA chemical feed. Output is set by stroke length and stroke frequency, and the pump can follow external contact signals from a controller such as the Aegis II.

The beta series covers capacities from 0.16 to 8.45 gph (0.59 to 32 L/h) at pressures up to 363 psi depending on model, with auto-degassing liquid ends for off-gassing chemicals and an integral bleed valve to prevent priming issues.
