Pump with lock-out feature

A method for controlling a flow parameter of a pump, said method comprising the steps of:

• providing a pump, said pump comprising:
• a pumping means for pumping fluid, said pumping means having at least one flow parameter;
• a control means for controlling said at least one flow parameter of said pumping means, said control means coupled to said pumping means;
• and
• a control panel coupled to said control means, said control panel having a plurality of controls operable by a human, said control means being programmable by operation of said plurality of controls, whereby said at least one flow parameter of said pumping means is programmed by a human by operation of said plurality of controls;
• said control means having a lock, said lock being activated by activation of at least two of said plurality of controls, said control means preventing alteration of said at least one flow parameter when said lock is activated;
• programming said at least one flow parameter of said pumping means by operating said plurality of controls;
• activating said lock by activating at least two of said plurality of controls, thereby preventing alteration of said at least one flow parameter of said pumping means until said lock is deactivated.
