The pump curve of a heating pump displays the feed rate on the x-axis and the delivery head on the y-axis.
The dry running alarm is triggered if the motor is running and the flow rate is less than 0.07 m³/h and the pressure is lower than the pressure set on the pressure switch.
The dynamic total delivery head is also referred to as the
The number of switching cycles is unlimited, as the SQ/SQE is equipped with soft start integrated into the motor.
A: Circulator pumps are generally used to circulate hot water. The temperature of the pumped medium is transferred to the pump, and it is normal for the pump's surface to be warm or even hot.
Dry running of the pump can damage the mechanical seal and the motor.
Yes, that is possible. To do so, connect one phase and the neutral conductor. The voltage between phase and neutral is 230 V.
In order to increase the service life of both pump and motor, weather protection should always be provided.
No, this is not possible
These days, heating systems are designed as hydraulically closed systems.
