Features (depending on model)
- Use of standard and cheap squirrel cage motors
- Control can be manual, pneumatic or electrical and can provide speed regulation controlled by parameters varying with the driving speed such as pressure, flow, liquid level, etc
- Direct, instantaneous response and accurate regulation
- Starting-up a motor under no-load conditions and progressive acceleration of the driven machine in conjunction with application requirements
- Silent operation even at high speed
- No monitoring, no special maintenance requiring skilled labour
- High efficiency
- Low investment cost
- No generation of harmonics and interference in the power supply network
- On existing installations, no requirement to change the motor or the pump
