· Irrigation in agriculture and greenhouses

· Sewage and wastewater lift stations

· Industrial process cooling water loops

· Chemical and slurry pump control



Application Case Study: Rural Water Supply Station

Challenge: A remote pumping station operated at full speed regardless of demand, wasting energy and requiring frequent maintenance.

Solution: A 45kW VFD with pressure feedback sensor was installed, adjusting pump speed in real time.

Results:

· Reduced energy consumption by 42%

· Cut pump maintenance frequency in half

· Improved water pressure stability across all endpoints

· Enabled remote monitoring via GSM module



Benefits of Using VFDs for Pumps

· Energy Efficiency: Eliminate over-pumping and reduce electricity bills

· Process Stability: Maintain consistent pressure or flow under variable demand

· Longer Equipment Life: Gentle start/stop protects pipes, valves, and bearings

· Flexible Automation: Supports multiple control modes and sensors

· Smart Alarms and Protections: Prevents pump damage from dry run or clogging
