Precision pumping system for spray treatment cycles

A system for spraying a skin treatment solution, comprising:

• a controller operable to control a plurality of precision pumping systems;
• at least one spray nozzle fluidly coupled to the plurality of precision pumping systems, a precision pumping system comprising:
• a positive displacement pump in fluid communication with the at least one spray nozzle, the positive displacement pump comprising a displaceable member, displacement of the displaceable member corresponding to a pumping cycle of the positive displacement pump;
• the positive displacement pump in communication with the controller, the controller being operable to apply a predetermined actuation parameter to direct an expected displacement of the displaceable member and being further operable to receive an indication of an actual position of the displaceable member;
• and
• wherein the controller is further operable to compare the predetermined actuation parameter associated with the expected displacement of the displaceable member to a measured actuation parameter associated with the actual displacement of the displaceable member.

A precision sprayer system for spraying a skin treatment solution, comprising:

• a piston pump comprising a piston and a linear actuator, the linear actuator operable to displace the piston during a pumping cycle of the piston pump;
• a position sensor operable to detect a flag coupled to the piston, detection of the flag corresponding to a known position of the piston;
• a controller in communication with the linear actuator, the controller being operable to apply an actuation parameter to direct a displacement of the piston and being further operable to receive a signal from the position sensor upon detection of the flag;
• at least one sprayer nozzle receiving a skin treatment solution from the piston pump;
• and
• wherein the controller is further operable to compare a predetermined actuation parameter associated with an expected displacement of the piston to a measured actuation parameter associated with an actual position of the piston.
