A pressure washer's performance is measured in both pressure and flow. Both are important. Plus you need to consider where the machine the machine will be used, what application you will be using it for and how much work it will do.
Pressure washers use water at high pressure for washing a variety of vehicles and machinery and for cleaning any type of washable surface or floor. They can be used in a wide and varying number of sectors e.g. agriculture, automotive, car washing, engineering, food preparation, industrial, marine and transport industry – to name but a few.
High pressure hot water cleaners are ideal for heavy duty users. They feature a compact design and easy to use controls, housed within a durable fibre glass or stainless steel cover fitted to a stove enameled hard wearing chassis and frame with solid tyres. Contained within are self-priming pumps with heavy duty fibre seals and brass cylinder heads and components, hard wearing nylon valves and stainless steel valve seats, providing various options of pressure, flow and performance.
High pressure cleaners are divided into 3 main groups – cold water cleaners, hot water cleaners and static units.
You need a hot water pressure washer when grease oil or fat needs to be removed. A cold pressure washer could be used in these circumstances, but would need to use a higher concentration of chemical.
A pressure washer consists of a pump and a motor. The motor drives the pump which creates the water pressure. Being under pressure the water is pumped out at high speed. The pump ensures a constant amount of water is produced, the water pressure can be varied by altering the size of the nozzle at the end of the lance.
Mobile units for cleaning on demand, and developing pressures of up to 5000psi. Machines can be fixed or static. Traditional high-pressure cleaners are often mobile units, and can be connected to services by the operator each time they are used. The operator then has access to settings including the detergent, flow, temperature and pressure. The operator then has access to settings including the detergent, flow, temperature and pressure.
Static cabinet machines are housed in a strong steel lockable container, permanent connections are made to mains power, water services, and fuel. The controls for temperature, flow, pressure, and detergent are all contained inside the cabinet. Stainless steel statics are ideal for external situations such as lorry washes in transport yards.
