Abstract: A battery powered fluid sprayer includes a reciprocating positive displacement pump, a power supply that includes a battery, an electric motor, a motor controller, a user-adjustment mechanism for setting a user-adjustable pressure threshold corresponding to system fluid pressure of the battery powered fluid sprayer, a pressure switch, and a power controller. The pressure switch generates a pressure signal indicative of whether the system fluid pressure is greater than the user-adjustable pressure threshold. The power controller is configured to control power of the battery powered fluid sprayer by providing operating power of the motor controller in response to the pressure signal indicating that the system fluid pressure is less than the user-adjustable pressure threshold, and not providing the operating power of the motor controller in response to the pressure signal indicating that the system fluid pressure is greater than the user-adjustable pressure threshold.

Abstract: A transfer pump includes a drive module having electronic components and a fluid module not including electronic components. The drive module provides motive power to a pump of the fluid module to power pumping by the fluid module. A control module is configured to monitor operation of the transfer pump and control pumping by the transfer pump. The control module is configured to receive dosing commands from a user interface, recall a dosing parameter based on the dosing command, and cause the drive module to operate the fluid module based on the dosing parameter to cause the transfer pump to output a set volume of material.
