Test results
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

A: Six times higher
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Seven times higher
Q: Why must the pump unit be installed below the dynamic water table?
A: So you are sure to minimise your power bill.
Q: Why must the pump unit be installed below the dynamic water table?
A: To avoid the risk of dry-running during operation.
Q: Why must the pump unit be installed below the dynamic water table?
A: To maintain a stable pressure in the system.
Q: Is the SQE pump able to provide constant pressure?
A: No.
Q: Is the SQE pump able to provide constant pressure?
A: Yes.
Q: Which protection features does the SQE have?
A: Voltage handling, soft start, dry-running protection and overload protection.
Q: Which protection features does the SQE have?
A: Protection against the well running dry.
Q: Which protection features does the SQE have?
A: The SQE does not have any protection features.
