Q: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Q: What is the benefit of a slow increase in speed?
A: It keeps pump movements at a minimum
Q: What is the benefit of a slow increase in speed?
A: It removes the need for motor contactors
Q: How does the integrated dry-running protection work?
A: It automatically restarts 3 minutes after shut down.
Q: How does the integrated dry-running protection work?
A: It prevents sand from damaging the pump.
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
