Pump start-up TS curve
Thread Content
In a technical request from a user (abroad), it is required to provide the \"pump start-up TS curve, showing the rotational inertia of the impeller as well as the torque at full load and zero flow rate.\" One curve should represent the damper being fully open, and another curve should represent the damper being closed. This pump is an IH50-32-200 type chemical pump; the fluid handled is water, with a flow rate of 12.5 m3/h and a head of 50 m. Its power requirement is 5.5 KW. Does anyone know where I can find the corresponding performance curve?
I have to hold on by myself; no one can help me
Since the starting torque and rotational speed variations are related to the motor connected to it, the motor’s starting curve can be used as a reference; generally, a starting time of no more than 5 seconds is considered acceptable
