Variable Frequency Drive (VFD) Systems in Western Canada
Match Pump Output to What the System Actually Needs.
Sego sizes, supplies and integrates VFD systems that adjust pump speed as system demand changes, helping maintain pressure, reduce cycling and improve pump control.
Where a VFD Pays Off
Demand That Changes Throughout the Day
When system demand rises and falls, a VFD can adjust pump output instead of running at full speed continuously.
What matters: Demand range · Minimum flow · Operating profile
Pressure That Needs to Stay Steady
Variable-speed control can maintain a pressure setpoint as fixtures, processes or zones move in and out of service.
What matters: Pressure setpoint · Sensor location · Flow variation
Cycling That Is Hard on Equipment
Frequent starts and stops increase mechanical and electrical stress on pumps and motors.
What matters: Start frequency · Pump sizing · Low-demand operation
What Determines the Right VFD Strategy?
01
Pump & Motor Compatibility
Horsepower, voltage, motor characteristics and pump operating range all affect drive selection.
02
Operating Range
The expected minimum and maximum demand determines how far the pump needs to turn down.
03
Control Variable
Pressure, flow, level or another process condition determines how the drive responds.
04
Minimum Flow Requirements
Some pumps or systems require minimum operating limits even when demand is low.
05
Multi-Pump Sequencing
Lead/lag logic and pump staging may be required when one pump cannot efficiently cover the full demand range.
06
Communications
BAS, SCADA or remote monitoring requirements influence drive and control architecture.
What Goes Into a VFD Pump System
A complete VFD system combines the drive, sensing, control logic and integration needed to adjust pump output around actual demand.
Variable-Speed Drive
Control motor speed to match pump output to changing system requirements.
Pressure & Process Sensing
Provide continuous feedback on pressure, flow, level or other critical process conditions.
Control Logic & Protection
Configure how the drive responds while protecting the motor and pumping system.
System Integration
Connect the VFD with pumps, panels and broader control or monitoring systems.
Considering variable-speed pump control?
VFD or Conventional Pump Control?
A VFD varies pump speed to match demand.
Conventional controls primarily start, stop, protect and sequence pumps. Many systems use both.
