Understanding Pressure Washer Basics

Pressure washers utilize high-pressure water spray to remove dirt, grime, and other debris from surfaces. Understanding the core components and principles of operation is crucial for safe and effective use. At the heart of any pressure washer lies a pump, responsible for increasing the water pressure. Simpson pressure washers often feature robust CAT Pumps, known for their durability and performance.

Power comes from either a gasoline engine, frequently Honda engines in Simpson models, or an electric motor. The engine or motor drives the pump, creating the pressurized water stream. Water is drawn from a source – a garden hose is typical – and passes through the pump before exiting through a nozzle. The nozzle shapes the spray pattern and influences the cleaning power.

Key to understanding performance is recognizing the interplay between pressure (PSI) and flow rate (GPM). Higher PSI delivers more forceful cleaning, while GPM determines the volume of water, impacting how quickly an area can be cleaned. Familiarizing yourself with these basics will enhance your pressure washing experience.

PSI and GPM: Key Performance Indicators

Pounds per square inch (PSI) measures the force of the water stream, dictating its ability to lift dirt and grime. Higher PSI is ideal for tackling stubborn stains on durable surfaces like concrete. Conversely, lower PSI is preferable for delicate materials to prevent damage. Simpson offers models ranging from 2100 PSI for lighter tasks to 3600 PSI and beyond for heavy-duty cleaning.

Gallons per minute (GPM) indicates the volume of water delivered. A higher GPM means faster cleaning, as more water washes away debris. However, GPM also impacts water consumption. A balance between PSI and GPM is essential; high PSI with low GPM can be inefficient, while low PSI with high GPM may not provide sufficient cleaning power.

Understanding these metrics allows you to select the appropriate Simpson model and nozzle for each cleaning job. A combination of both results in “Cleaning Units”, a measure of overall cleaning performance.
