A method for pumping, tracking, and controlling a fluid includes the steps of producing a drive signal for driving a motor of a pump using a controller, driving the motor to pump a fluid based on the drive signal, sending a dispense signal from the controller to a sprayer for dispensing the fluid, determining a work piece count as a function of a work piece signal provided to the controller from the work piece sensor, detecting the position of a rod connected to the motor and the pump using a position sensor, creating a position signal as a function of the position of the rod using the position sensor, sending the position signal to the controller, and determining a volume usage as a function of the position of the rod using the controller.

A pressure washer includes a prime mover, a pump driven by the prime mover, and a spray gun fluidly coupled to the pump. The spray gun includes a flow-control valve movable between an open position and a closed position to control a fluid flow from the spray gun, a user interface for controlling the flow-control valve, a sensor configured to detect the state of the user interface, and a first wireless system electrically coupled to the sensor. In a first state of the user interface, the flow-control valve is in the closed position. In a second state of the user interface, the flow-control valve is in the open position. The pressure washer further includes a second wireless system electrically coupled to the prime mover. The second wireless system signals the prime mover to start to drive the pump to provide fluid to the spray gun upon receiving a start signal from the first wireless system indicating that the sensor detects the user interface in the second state.

An ejection device includes a nozzle that ejects an ejection fluid, an ejection-side pump, a driving-side pump, and a heating unit. The ejection-side pump includes a pressure transmitting member, and an ejection chamber and a driving chamber adjacent to each other across the pressure transmitting member. The ejection chamber is filled with the ejection fluid. The driving chamber is filled with a driving fluid. The driving-side pump is a pump that applies pressure to the driving fluid. The pressure transmitting member transmits the pressure applied to the driving fluid to the ejection fluid in the ejection chamber. The heating unit heats at least the ejection-side pump while the driving-side pump remains unheated.

A pump system for pumping a fluid includes a motor housing, a motor, a rod, a positive displacement pump, a position sensor, and a controller. The motor is located within the motor housing. The rod is connected to and driven by the motor and the positive displacement pump for moving a fluid is driven by the rod. The position sensor produces a rod position signal that is a function of a position of the rod, and the controller produces a drive signal for driving the motor as a function of the rod position signal.

A device for conveying viscous material out of a barrel-like container which has a container base and a container shell which extends upward from the container base, having a follower plate for closing off the container. The follower plate having a material outlet opening and a ventilation opening. There is a pump for conveying the viscous material through the material outlet opening, and a ventilation device for introducing compressed air through the ventilation opening, and a lowering device for lowering the follower plate in the container. A discharge valve is provided which, in a first switching position, blocks a line which leads out of the first pressure chamber, and which, in a second switching position, opens the line for the purposes of discharging pressure medium out of the first pressure chamber.

The invention relates to a paint spraying unit which includes a paint pump, a paint storage container, a paint spraying device, a paint line and a drive device, where the drive device drives the paint pump and the paint pump conveys paint out of the paint storage container through the paint line to a nozzle of the paint spraying device. In this connection, the drive device includes a compressed air rotation motor as the motor.

A two-component pumping system includes a first pump for pumping a first component, a second pump for pumping a second component, a motor, and a yoke assembly for connecting the motor to the first pump and the second pump and driving them simultaneously. The first pump includes a first displacement rod that reciprocates in a first pump axis. The second pump includes a second displacement rod that reciprocates in a second pump axis parallel to the first pump axis. The motor includes a drive shaft configured to reciprocate in a drive axis that is parallel to and in a common plane with the first and second pump axes. The motor is also configured to drive the first and second displacement rods in unison. The yoke assembly includes a top connector and a shoe. The top connector connects to the drive shaft.

A ground marking system includes a position signal receiver configured to receive a position signal and generate current position information based on the position signal. A paint supply is configured to discharge paint onto ground beneath the paint supply. A first actuator is operatively connected to the paint supply for linearly moving the paint supply in both a first direction and a second direction opposite the first direction. A second actuator is operatively connected to the paint supply for controlling the discharge of paint from the paint supply. A memory device stores predetermined positional data. A processor is in communication with the position signal receiver and the memory device, and is configured to control linear movements of the first actuator based on the current position information received from the position signal receiver and the predetermined positional data stored in the memory device, and adjust a position of the paint supply.

The disclosure relates to a paint system for coating components with a coating medium, in particular a painting system for painting motor vehicle bodywork components with a paint, comprising at least one pneumatic pump for circulating paint in the system. The pneumatic pump includes a feed air connection for feeding in a feed air stream for mechanically powering the pump and an exhaust air connection for conducting away a depressurised, cold exhaust air stream. The cold exhaust stream passing through a first heat exchanger where the heat exchanger cools a medium in a cooling circuit and the medium cools a heat-sensitive component. The heat sensitive component can be the paint circulation lines or a protective housing for the robot.

A system includes a material sensor system having an inlet and an outlet. The inlet receives a flow of a material and the outlet outputs the flow of the material. The material sensor system includes an inner cavity having a surface, where the inner cavity receives the flow of the material. The material sensor system also includes a float system having one or more floats, where the one or more floats float within the material of the inner cavity. The material sensor system also includes a switch that sends one or more signals to a control valve system when the float system engages the surface of the inner cavity.
