1. A transfer pump configured to pump material, the transfer pump comprising:
a fluid module including a fluid moving member configured to reciprocate along a pump axis to pump the material; and
a drive module including:
an electric motor operatively connected to the fluid moving member to power reciprocation of the fluid moving member; and
a control module operably connected to the electric motor, the control module configured to:
enter a learning mode based on the control module receiving a learning mode command from a user interface, the learning mode command generated based on actuation of a second input of the user interface;
receive a dispense command from the user interface based on manual actuation of a first input of the user interface while in the learning mode, the first input different from the second input, the dispense command having a duration representative of how long the first input of the user interface is manually actuated, wherein, while in the learning mode, the control module activates the electric motor to cause pumping of the material while the first input is manually actuated and causes the electric motor to stop pumping of the material based on release of the first input;
monitor operation of the drive module while operating the electric motor to power reciprocation of the fluid moving member to pump the material in response to the dispense command while in the learning mode and store, in a memory of the control module, an operating parameter associated with a volume of the material dispensed while pumping based on the dispense command in the learning mode as a dosing parameter, the volume forming a dose volume;
exit the learning mode based on release of the first input and enter into an operating mode other than the learning mode based on the release of the first input;
receive a dosing command from the user interface;
recall, from the memory, the dosing parameter based on the dosing command; and
operate the electric motor based on the dosing parameter and in response to the dosing command to cause the electric motor to drive reciprocation of the fluid moving member such that the transfer pump outputs the dose volume.
