Why is the flow rate lower than expected in my Pulsafeeder PulsaPro PP680?
A lower than expected flow rate in your Pulsafeeder Water Pump can stem from several causes. The motor speed might be too low; check the voltages, frequency, wiring, and terminal connections, and compare the nameplates against the specifications. Worn or dirty check valves can also be the culprit, so clean or replace them if damaged. Other potential causes include a hydraulic bypass valve operating each stroke (refer to the Hydraulic Bypass Valve), a calibration system error (evaluate and correct), product viscosity being too high (lower viscosity, increase pump and/or piping size), product cavitation (increase suction pressure), a piston seal worn or damaged by contamination (inspect and replace if necessary), or a process pressure relief valve leaking or relieving (repair, adjust, or rep...
