About products and suppliers

A pressure sprayer, also known as a pressure washer, is a device used for cleaning, as well as sprinkling water and other liquid chemicals. It's a versatile tool widely used in different work scenarios such as cleaning driveways and vehicles, maintaining gardens and lawns, and some industrial applications.

Different types of pressure sprayers

Pressure sprayers can be categorized by their different sources of energy. Electric power sprayers use electricity and are applied in duty tasks such as washing vehicles and commercial cleaning. Gas-powered pressure sprayers are designed to help with heavy duties such as cleaning driveways. This particular type is reliable equipment for construction, agriculture, and heavy industry. All of these pressure sprayers are available in various sizes to meet different kinds of use purposes and scenarios. Basically, types for household or residential scenarios are in smaller sizes than those of commercial and industrial functions. And commercial types can generate higher water pressure to ensure the use effects. There are also more portable types of pressure sprayers, mostly air pressure sprayers, designed for light tasks. Their common functions include gardening and agricultural activities such as watering plants and applying pesticides and fertilizers, as well as some cleaning. Most of them are hand pump sprayers, with hand-held pump sprayers and backpack garden sprayers as common types.

Components and materials of pressure sprayers

Pressure sprayers are typically composed of many parts including pumps, nozzles and tips, tanks, seals, and valves. These components are made of various kinds of materials and each of them has different properties. Since the pump is the component that generates water pressure, its durability and resistance to rust are crucial. Thus, materials that are commonly used on pumps are brass, stainless steel, or aluminum. For nozzles and tips, they are usually made of stainless steel, brass, ceramic, and plastic to create a high-pressure water stream. Valves that control water flow and pressure can be made of brass, stainless steel, or plastic. As for the tanks, it needs to hold the liquid all the time. Therefore, it has to be durable and resistant to chemicals, and it has to be easy to clean. It also needs to be lightweight for manual operation. Taking these factors into consideration, materials such as polyethylene are ideal choices for making tanks. Watertight seals are commonly made of rubber or synthetic elastomers. And valves made of plastic, brass, or stainless steel can do a good job in controlling water. Other components like straps and grips should focus on comfort and stability.
