Pressure washer pumps are an essential component of any pressure washing system. These pumps are responsible for pressurizing the water, allowing it to blast away dirt, grime, and other debris from surfaces. There are several types of pressure washer pumps available, including axial cam pumps, triplex plunger pumps, and direct drive pumps. Each type of pump has its own unique features and benefits, and the right one for a particular application will depend on factors such as the amount of pressure needed, the type of surface being cleaned, and the frequency of use. Regardless of the specific type of pump chosen, a high-quality pressure washer pump will provide reliable performance and efficient cleaning power.

Buying Guide Image

A Guide to Selecting Pressure Washer Pumps

It is common knowledge that to carry out washing at high pressure; you need a pressure washer pump. Purchasing the right one entails having the knowledge of several other factors such as the pressure washer hoses to be used, and the pressure washer gauges.

Thankfully, this guide details all that you need to know to aid you to make the right decision when purchasing pressure washer pumps.

Factors to consider before buying pressure washer pumps

Pump Design: There are three main pressure washer pump designs; axial cam pumps, Triplex pumper pumps, and Wobble pumps.

  • Wobble Pumps: This is the most basic type of pressure washer pump. It utilizes pistons and is driven by a driveshaft. The driveshaft pushes the piston back and forth, causing it to suck in and push out water at high pressures.
  • Axial Cam Pumps: These kinds of pumps can also be referred to as swashplate pumps. It also makes use of pistons and is driven by a driveshaft. For it to work, the piston is stroked by the swashplate, sucking in water and forcefully throwing it out from the other end. There are two types of this pump design; the fixed and the variable which allows you to adjust the angle of the swashplate.
  • Triplex Pumper Pumps: This is the most efficient type of pressure washer pump and is very suitable for professional use. This type of pressure washer pump is very strong and can push water out at much higher pressures than the other types.

Brand: Pressure washer pumps are not the types of machines that you can just purchase anyhow. You need to go for reputable brands such as Yamatic, Homelite Universal, and Honda Excell, which comes along with usage guarantees as well as expert guidance when needed.

Water Pressure: The different pressure washer pumps come with different pressures rated as PSIs. The higher the PSI, the higher the pressure with which the water pumps out. A pressure washer pump with a low PSI can affect the cleaning output as high-pressure water expulsion aids in removing those tough dirt.

Benefits of Pressure washer pumps

Removing Tough stains: Pressure washer pumps ensure that those tough stains are easily removed. This is because of the pressure with which the water is pumped out.

Saves Time: Tough stains can be a time killer when cleaning manually. However, pressure washer pumps save you the time that would have been wasted by swiftly removing those stains, no matter how tough they are.

Cost-Effective: Most times we may not realize that we have spent more than necessary when trying to remove tough stains.

However, a one-time purchase of a pressure washer pump can save you that extra money.

Frequently Asked Questions (FAQs)

What Kind of Detergent can I use in my pressure washer pump?

Every type of detergent can be used with a pressure washer pump. However, you can still refer to the user guide of the particular brand you purchase to know if there is a specific type of detergent for that brand.

How will I know my pressure washer pump PSI rating?

Simply check the user manual for the rating. Also, most brands boldly imprint the rating on the product packaging.

Frequently Asked Questions (FAQs)

1. What type of pump is best with pressure washers?

The best type of pump for pressure washers is a high pressure pump, specifically a positive displacement reciprocating pump like a plunger or piston version. Plunger pumps are more common, as they are more efficient and have a longer lifespan.

2. How do I choose a pressure washer pump?

When choosing a pressure washer pump, you need to match the pressure rating (PSI) and gallons per minute (GPM) of your old pump with the available replacement. It's important not to go for a pump that offers much higher PSI, as it can strain the engine or be too powerful for your hose's burst rating.

3. Which is better axial or triplex pump for pressure washer?

Both axial and triplex pumps have their advantages. Axial cam pumps are direct drive and offer high pressure and performance but have a shorter lifespan. Triplex plunger pumps are of higher quality, providing longer life and better performance.

4. How many PSI Do I need to clean concrete?

To clean concrete, you will need a powerful pressure washer with high pressure levels of around 3000 PSI. However, if you plan to clean a variety of surfaces in addition to concrete, it's recommended to choose a pressure washer with adjustable pressure levels and set it to around 3000 PSI for concrete cleaning.

5. How can you tell if your pressure washer pump is bad?

There are several signs of a bad pressure washer pump, including water or oil leaks, inconsistent or low pressure, and loud noises. If your pump has a crack or leak, it may need to be replaced. Similarly, damaged seals, gaskets, or pistons can cause oil leaks. Inconsistent pressure or low pressure are also indicators of a faulty pump.

6. What is the life expectancy of a pressure washer?

The life expectancy of a pressure washer can vary depending on the type. A standard vertical shaft power washer typically has a life expectancy of 100 hours, while a standard horizontal shaft pressure washer can last up to 400 hours.
