Pumps in duty, assist, or standby
Water & wastewater
Drives that hold pressure, stage pumps, and keep flow moving
Match pump speed to real pressure and flow demand, stage multiple pumps without a separate PLC, and protect stations against dry running, blockages, and leaks. Optidrive Eco brings pump-focused control into one VFD.

Why drives matter
Where pump control earns its place
Water and wastewater systems rarely run at one fixed demand. A properly selected drive can hold pressure, stage pumps as flow changes, and protect equipment before a blockage, dry-run condition, or leak turns into downtime.
Up to 5
Pumps on one master drive
Hold pressure as demand rises and falls
A single master VFD can control and monitor up to five pumps in duty, assist, or standby modes. As demand changes, the station can maintain the required pressure and flow while bringing assist pumps online only when they are needed.

Auto
Blockage detect and clear
Clear a blockage before it becomes a callout
Wastewater pumps can accumulate sediment and blockages. Optidrive can detect a blockage and run a cleaning programme to clear it, while dry-run protection can stop the pump before an empty condition causes avoidable damage.
Blockage detection and clear
PID
Pressure matched to demand
Stop wasting energy across throttling valves
When flow and pressure demand fall, a drive can slow a centrifugal pump instead of forcing the system to waste energy across a throttling valve. Built-in PID control lets the station regulate pressure against the real setpoint.

Applications and drives
Drives we recommend for water and wastewater
Application 1 of 6
Potable-water booster systems
Pressure-controlled booster sets that maintain service as demand changes, stage assist pumps when required, and use sleep mode to avoid hunting around the target pressure.

Payback months
Formula: motor kW x annual hours x energy cost x savings rate, where motor kW is HP x 0.746. The savings rate comes from the pump affinity laws: power falls with the cube of speed, so a drive saves energy only by running the pump below full speed, and the saving shrinks as static head rises. Drive losses of about 3 percent are included. Payback uses the entered drive price, or the recommended one when blank. Verify against the pump curve for critical sizing.
