A catheter pump system with a pump having a fluid displacement member in the blood flow channel, a motor and a motor controller having a pressure sensing port for connection to a control pressure source. The motor controller is arranged for causing motor speed to be increased in response to a reduction of pressure applied to the pressure sensing port and for causing motor speed to be reduced in response to an increase of pressure applied to the pressure sensing port. The motor may be a pneumatic motor for driving the pump and the motor controller may be arranged for controlling motor speed by reducing flow through a supply channel to the motor and allowing an increase of flow through the supply channel to the motor in response to control signals received via an input interface.
