A method for colouring turf and a turf colouring system. The method and system comprise delivering liquid colourant at a hydraulic pressure greater than 1000 psi to sprayers having a high pressure, high impact, fine spray nozzle with a spray pattern having feathered edges for even coverage with overlapping nozzles. Alternatively, the method and system comprise delivering liquid colourant at a pneumatic pressure greater than 60 psi to sprayers having a high pressure, high impact, fine spray nozzle with a spray pattern having feathered edges for even coverage with overlapping nozzles.

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.

A pump arrangement, in particular in a coating installation for the coating of components, such as a painting installation for the painting of motor vehicle body components, is provided. The pump arrangement includes a plurality of adjustable pumps for delivering a coating agent, e.g. for delivering a sealing agent for the sealing of weld seams on a motor vehicle body component. The pumps are connected in parallel such that the pumps extract the coating agent for delivery from a common inlet line and deliver said coating agent into a common outlet line. The arrangement further includes a control device for the open-loop or closed-loop control of one fluid variable at the outlet of the individual pumps, respectively, wherein the control device actuates the individual pumps individually, and/or a monitoring unit, which switches the pumps on and off non-simultaneously.

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 self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. Each liquid ejecting element takes the form of a piston disposed within a cylinder. The pistons responds to pressurized fluid imposed directly thereon from the source to generate the motive force on the ejecting element.

A high pressure water cleaner with detachable water tank includes a water cleaner main unit having an internal hydraulic pump, a top receptacle and a feed water connector in the receptacle in communication with the hydraulic pump, and a water tank detachably insertable into the receptacle and lockable to the receptacle by a movable lock. Thus, the water cleaner main unit and the water tank can be used together or separately subject to different application requirements.

Disclosed is a nozzle rotation mechanism that is small in size, has a simple structure, and can accurately adjust the rotational direction of a nozzle tip. Also disclosed is a coating device provided with the aforementioned nozzle rotation mechanism. The nozzle rotation mechanism is provided with: a nozzle having a discharge outlet from which a liquid material is discharged; a nozzle unit having a channel that connects the nozzle and a liquid material supply source; a base member; and a rotation device that is provided on the base member and rotates the nozzle unit. The nozzle is disposed in the nozzle unit such that the centerline of the discharge outlet of the nozzle forms an angle with the rotational centerline of the nozzle unit, and the nozzle unit is removably mounted to the rotation device.

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.
