A Guide to the Main Components of a Pressure Washer

Various types of motors are used in different kinds of pressure washers. It may even vary depending on the kind and setting of the applications. The large majority of high pressure washers utilised in professional works, normally use gasoline or diesel-powered engines. Since the majority of commercial cleaning needs large amount of time, these engines could run for a longer time without overheating versus their electric equal. And because most professional works are executed out-of-doors; and often or mostly offsite, where there isn’t any available source of electricity. Those with electric powered engines are typically employed for light to moderate washing works (e.g. home, automobile, and smaller watercraft) and are best used in interior applications because these engines do not produce hazardous gases.


You have now reached the “core” of the pressure washer model, the high pressure pump motor. Each one is positive displacement reciprocating pumps either piston or plunger types. commercial pressure washer Plunger pumps are the most efficient and have a extended life, as a result these are by far the most often used pumps found on a top quality pressure washer right now.

You will find duplex and triplex plunger pumps. Plungers are typically produced from ceramic, an extremely tough material with terrific wear resistant traits. The triplex pump has become the most in-demand due to more stable flow it makes.

These pumps can be really robust and virtually hassle free whenever thoroughly looked after. Most people are suspicious of the pump when first encountering difficulties but astonishingly 90% of issues can be traced to causes aside from the pump.


These simple apparently minor parts are what make the whole high pressure system work. Pressure washer nozzles possess a small spray hole which can be sized to produce the required pressure at the certain flow. This pinhole is a constraint in the water flow. Once the flow from your pump is forced through this restriction, pressure is created. It is only now that you have a pressure washing system. Pressure washer nozzles with an orifice which is most closely sized to the specifications of the pump provide you with the maximum efficiency. The high pressure nozzle is a considerably more important element of the power washer than most recognize. This generates the restriction which allows water flow to get “pressurized” and delivered with such force. A worn nozzle will diminish pressure clearly. A mismatched spray hole might have the same effect. A nozzle with little to no wear and one with an hole correctly sized to the pumps’ output can get the best functionality from your device.


A high pressure hose comprises an inner tube into which the water passes. This can be packaged in either a solitary or a double braid of wire mesh. It is in turn surrounded by a rubber exterior cover. The less expensive hoses are covered in a thermoplastic material, while the better hoses have rubber covers. Most hoses are produced with burst ratings four times their graded working pressure. While matching hoses for pressure washers try to use a hose rated slightly higher than the psi rating of your pressure washer. It’s going to last longer. Normal psi ratings are 3000psi, 4000 psi, 4500 psi, 5000psi and 6,000 psi. 3,000 and 4,000 psi hoses are generally single braid while 5,000 psi and greater are practically always double braided (2-wire).
