WATER

Typical Applications

• Water pumps
• Sewage pumps
• Vertical Hollow Shaft pumps
• Submersible pumps
• Starting from Diesel Generators (weak mains supply)

 Special Functions for Water Pumping Application:

• Reduced inrush current & mechanical shock Smooth, step-less acceleration & deceleration Unique soft starting and stopping characteristics Heavy duty, fully rated design
• Sophisticated motor protection package
• Ease of installation and operation
• Preparation for harsh environmental conditions Prevention of Over Pressure & Water Hammer

 How can you Protect Water Systems with Solcon Soft Starters?

• Start Curves - Solcon’s Soft Starters incorporate an Intelligent Pump Control algorithm that offers selection between five special dynamic voltage ramp-up curves, and Torque or Current curves. Reduces peak torque, thus, extends acceleration time.

• Stop Curves - When pumping to a higher elevation and when the motor is soft stopped, motor torque may quickly fall below load torque causing abrupt stalling instead of smoothly decreasing speed to zero. This may create a Water Hammer phenomenon resulting in a loud noise, disturbances and damage to the piping network. The Pump Control enables selection between four dynamic voltage ramp-down or Torque curves to prevent a stall condition and eliminate Water Hammer.

• Final Torque - Prior to concluding the deceleration process, motor torque reaches a level where the load torque is higher than motor’s torque and the valve closes. The motor continues to run against a closed valve (no load) until it stops. The Final Torque feature enables setting a point where the motor stops when the valve closes, thus eliminating operation without water.
