When the AC is on the pump should not go on and off so if it is there is something wrong with that part of the system.
When correctly charged, it is normal for the compressor to cycle on and off. It does this to prevent the temperature of the evaporator coil from dropping low enough to cause icing.
Excessive cycling frequency may indicate a low refrigerant charge.
