    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. The transfer pump further includes a spout extending mounted to an outlet connector of the fluid module by an inlet end of the spout interfacing with an outlet end of the outlet connector. The spout is repositionable relative to the outlet connector while mounted to the outlet connector.

    Abstract: A fluid dispensing system includes a motor housing and a piston pump assembly connected to the motor housing. A motor is mounted within the motor housing. The piston pump assembly includes a pump housing, a cartridge having a first end that extends into a second end of the pump housing, a piston that extends into a first end of the pump housing and the first end of the cartridge, and a packing stack within the cartridge and adjacent an inner surface of the cartridge and through which the piston extends. The cartridge is configured to be removed from the pump housing, and removal of the cartridge removes the packing stack from within the pump housing while leaving the pump housing connected to the motor housing.

    Abstract: A handheld sprayer includes a housing, a turbine, a spray tip, and a hopper. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and configured to discharge a fluid into the air flow passage. In one embodiment a valve is positioned within the air flow passage and configured to control the airflow from the turbine to the spray tip. In another embodiment, a voltage limiting circuit is configured to control voltage to an electric motor of the turbine to control speed of the turbine. In another embodiment, an air inlet control device is configured to control the air intake of the turbine.
