The pump will have a torque versus speed characteristic curve. This curve can be calculated from the pump characteristics.
The motor will have a torque versus speed characteristic curve. This is essentially the torque/slip diagram with a change of units (converting slip to speed).
When the motor drives the pump, the system will accelerate as long as the motor torque is greater than the pump torque. The acceleration will stop when the torques are equal.
For the motor to be matched to the pump, the point of intersection needs to be at a reasonable normal operating point for the motor. Additionally, the motor must be able to accelerate up to this point; either there must be no intersections at lower speeds, or there needs to be a way to 'unload' the pump to permit the startup acceleration.
