Mechanical sealing solutions for pumps and industrial machinery.
Variable Frequency Drive
VFD — Variable Frequency Drive
A VFD controls motor speed by varying supply frequency and voltage — giving smooth starting, precise speed control and, for pumps and fans, significant energy-saving potential.

Technical overview
What a VFD controls
- Motor speed Hz / rpm
- Acceleration & deceleration
- Motor current A
- Output power kW
- PID control (e.g. pressure)
- Fault diagnostics
01Applications
- Pumps and constant-pressure booster systems
- Fans, blowers and HVAC
- Conveyors and material handling
- Machine speed control
02System integration
- Controlled by PLC over I/O or communication
- Drive data available to HMI and SCADA
- Energy data can be included in EMS
03Selection considerations
- Motor power, current and voltage
- Load type (variable or constant torque)
- Environment and cooling
- Harmonics and cable length considerations
Engineering support
More than supplying a VFD
Machine Lab reviews the application, recommends a suitable product and can integrate, install and commission it as part of the complete system.
