Pumps are an important part of any pressure washer. It is the pump that creates the pressure that makes your cleaning job easier and faster. A good pump will make sure you get the best results from your pressure washer.
The pump has two main parts, the motor and the pump head. The motor powers the impeller inside the pump head, which puts pressure on water before it is released through nozzles or attachments. The impellers are usually made from plastic or brass and can vary greatly in size depending on how much pressure you need. If you are to pressure wash driveway or other light-duty tasks like washing your car or patio furniture, then you will want to go with a smaller impeller that spins faster but does not put out as much force as a larger one would. On the other hand, if you plan on using your pressure washer for cleaning heavy debris from concrete or other surfaces that require more cleaning power, then choose an impeller that spins slower but produces more torque (rotational force).
Here are some of the most common types of pumps used in pressure washers:
Diaphragm Pumps
Diaphragm pumps are the most popular type found in residential pressure washers because they are easy to install and have a relatively small footprint. They also have low maintenance costs and can be used with other brands of pressure washers, which makes them ideal for people who have multiple machines at home or in their business. Diaphragm pumps are made up of two chambers: one contains water, while the other holds air. When you pull on a trigger on your wand, it opens up a valve and allows air to enter the chamber containing water, which causes suction through an intake valve on top of the pump. As more air enters this chamber, it creates more suction until you release your trigger or run out of hot water from your heater tank.
Gear Driven Pumps
Gear driven pumps are less expensive than diaphragm pumps, but they don’t last as long because they have moving parts that can wear out over time. Gear driven pumps are ideal for light duty tasks like washing cars or small jobs around the house like cleaning gutters or watering plants.
Piston Pumps
Piston pumps are the most common type of pumps in pressure washers. They’re usually found in gas-powered pressure washers, but they can also be used with electric ones. Piston pumps have an oil reservoir that lubricates the moving parts. When the trigger is pulled, this lubricant is forced out of a hole at the bottom of the pump body through a nozzle; this causes water to be drawn up into the pump body from below and pushed out through another nozzle on top. The piston pump uses an impeller — or propeller — to help draw water into its body and push it out again at high speed.
Rotary Pump
A rotary pump is the most common type of pump used in pressure washers. It’s a positive displacement pump that uses centrifugal force to move fluid through the system. The rotary pump requires less maintenance than other pumps, but it also has lower flow rates and can be more expensive than other types of pumps.
Conclusion
There are a wide variety of pump options available within pressure washers. There are different sizes and various kinds of pumps. Pumps are often one of the more important parts to look at when finalizing a purchase on a pressure washer. As with purchasing any product it is vital to read reviews, follow forums and other places where people can share their experiences.
To sum up, when choosing a pump for a pressure washer, consider its power rating in PSI, GPM and water flow capacity. You can also inquire from the professionals at Giraffetools collections about different pump models.
