Variable speed booster pump systems
Variable speed booster pumps use inverter drives to match pump speed to water demand. They can improve pressure control and efficiency when correctly specified and commissioned.
Common faults
Faults can include inverter alarms, pressure transducer failure, unstable pressure, communication faults, motor overloads, poor commissioning, sensor drift or one pump not sharing duty correctly.
Useful information
Send the inverter fault code, pump make/model, controller display photos, pressure gauge readings and details of when the fault occurs.
Replacement and upgrades
Older fixed speed systems may sometimes be replaced with variable speed booster sets, but suitability depends on demand, pipework, controls, supply, space and budget.
