A peristaltic pump comprises a drive assembly, a hose pump, and a hose bracket. The drive assembly is rotatably disposed within a frame to move a roller along a pumping path with respect to the frame. The pump hose has rigid hose ends connected by a bendable hose section with limited flexibility tending to bias the pump hose towards a substantially unbent shape. The hose bracket has a rigid body with a first central opening sized to receive the rigid hose ends at first and second retention locations, such that the natural bias of the pump hose towards a substantially unbent shape retains the hose ends within the first and second retention locations, positioning the bendable hose section along the pumping path of the roller.

Environmental sanitizing device including a frame housing a disinfectant liquid reservoir and supporting a nozzle, the nozzle associated with a generation system of an air flow within which a plurality of disinfectant liquid particles are suspended to sanitize a closed environment in which the device can be positioned; the nozzle is movable with respect to the frame, and associated with positioning system controlled by a control unit for orientation of the nozzle with respect to at least two mutually perpendicular axes, preferably around a first vertical axis and around a second horizontal axis to automatically orient the nozzle in desired direction with respect to the frame during a sanitization step, the nozzle coupled with at least one distance detector able to determine distance between the nozzle and an obstacle facing the nozzle.

A system for spraying granular pasty matrices onto buildings. A spray gun for a wet mortar which makes possible the easy, safe and efficient spraying of wet mortars including aggregates with a particle size D50 of between 1 and 15 millimeters. The system which it concerns which includes spray gun for wet mortar provided with gun body, with at least one injector emerging in contacting chamber, at least one spray nozzle for mortar, and at least one connection end piece mounted on inlet of body for flow of mortar. Flow of mortar within the guiding duct of body is monodirectional or multidirectional (angular deviation<30°. The position of injection head of the injector in chamber is adjustable. The mortar is constituted by a pasty matrix including aggregates, fillers and additives. The aggregates have a D50=1-15 mm and a form factor F≠1.

This invention relates to a method and system of applying a fluid material to a roofing surface. By modifying a peristaltic pump-driven sprayer device, a fluid material having a viscosity of 10,000 to 40,000 centipoise at 25 C. can be effectively sprayed onto a roofing surface. Additionally, the use of a modified peristaltic pump-driven sprayer device allows for the fluid material to be applied onto the roofing surface at a faster rate than other spraying methods.

Systems for shredding fibrous material are described. In some embodiments, the system includes a cart that includes a hopper that includes an auger motor for shredding fibrous material and a blower motor configured to blow the shredded fibrous material onto structures for fireproofing. The cart may include a handle, one or more wheels, and/or forklift apertures to aid in transport.

Cleaning machine (100) comprising a nebuliser device (10) for nebulising a liquid product (115), a tank (110) containing said liquid product (115), an intake part (120) comprising at least one waste air vent (125), wherein said nebuliser device (10) comprises a dispenser (20) for dispensing said liquid product (115), a first connecting duct (211) which connects in fluid communication said tank (110) with said dispenser (20), a second duct (225) which connects in air-flow communication said at least one waste air vent (125) of said intake part (120) with said dispenser (20), wherein said dispenser (20) comprises a hollow body (21) comprising an inner cavity (25) connected in air-flow communication with said second duct (225), a dispensing tube (30) connected in fluid communication with said first duct (211), wherein a space is provided forming a nebulisation area (40) arranged at a mouth of an outlet pass-through opening of said dispensing tube (30) and at a mouth of a pass-through outlet opening of said inner cavity (25).

Apparatus and associated methods relate to remote priming of a texture sprayer. The texture sprayer includes a main unit, a hose assembly and a spray gun, the main unit includes an air compressor, a sensor that senses a parameter of air compressed by the air compressor, and a texture material pump that is activated and deactivated in response to the parameter sensed. A spray gun can be remoted coupled to the main unit via the hose assembly. The spray gun includes a nozzle, from which the texture material is forcefully expelled as a spray, a trigger, and a prime valve. Actuation of the trigger causes the spray gun to mix the compressed air with the texture material and to forcefully expel the texture material as a spray from the nozzle, thereby causing flow of the compressed air. Opening the prime valve releases the compressed air thereby causing flow of the compressed air.

A mobile pressure washer can include a wheeled chassis, a power plant supported by the wheeled chassis, a fluid pump a fluid pump coupled to and driven by the power plant, a sprayer in fluid communication with the pump, a chemical solution container, and a container holder for supporting the chemical solution container. In some examples, the container holder has a frame operably connected to the wheeled chassis and has a container support mounted to the frame, the container support including a base wall and a sidewall defining a receptacle for receiving and supporting a container in fluid communication with the pump.

An application system for applying a substance over a predetermined surface includes a frame movable over the predetermined surface, a pressurized carrier source, a vessel containing the substance. The system further includes a first conduit for conveying the substance from the vessel to at least one nozzle and a second conduit for conveying a pressurized carrier from the pressurized carrier source to the at least one nozzle for applying a mixture of the pressurized carrier and the substance over the predetermined surface. The system further includes a cover laterally surrounding the at least one nozzle for minimizing overspray of the mixture, the frame carrying the pressurized carrier source, the vessel, the first conduit, the second conduit, and the cover.
