What You Need to Know Before Buying a Pressure Washer Pump

The cleaning ability of a pressure washer is great, removing dirt, grime, and algae quickly, efficiently and effectively. A pressure washer can greatly increase your ability to maintain and clean your property and equipment giving it greater value.

A pressure washer comes with many parts, and one of them is the pump. Without it, the machine would not be able to achieve its cleaning objectives, that receives water from your hose, and pumps it through a tip at high pressure. There are several common types of pumps that you will see in commercial and home-owner type machines. All pressure washer pumps have pistons and valves similar to a gas engine or an air compressor. On some pumps the pistons are driven by a plate on an angle (wobble plate), and in other cases the pistons are driven by a crankshaft. Crankshaft driven pumps are generally built better and will last longer.

We'll cover the three main types as they're easier to understand for typical consumers.if you're wondering what category to pick for your new pump, here is what you should know.

1.Wobble Pump

Wobble pump is a kind of entry-level pump and it’s better for home use.

 This pump uses a wobble plate by connecting to the drive shaft that pushes the piston back and forth. Then the piston sucks in the water and pushes out water with huge force.

Large spring with the piston is a great matter as this allows the wobble plate to work against the piston. That’s the reason for this wobble pump being just 70% effective. This kind of pump is of low PSI and GPM. This pump can run dry, producing high pressures. This pump works usually 400+ hours. They can’t be repaired when spoilt and must be replaced. This type is best used in washers below 2500 PSI and a flow rate of less than 2 GPM.

2.Axial Cam Pump

This is a kind of intermediate level pump,It’s capable of higher GPM and PSI. The difference in design is that the pistons rotate around the swashplate that strokes the piston in this pump. Then the pistons suck up water from one side and push it out to the other side. The lifespan of the pump is twice or thrice that of wobble pumps. They’re used in washers with less than 3500 PSI.

To help narrow down your choices, We recommend for you some of the best pressure pumps you should consider:

The Yamatic pressure washer pump is a direct drive vertical axial pump. It fits most pressure washers with a vertical shaft, including Blackmax, Powerstroke, Troy Bilt, and Briggs & Stratton brands, washer pressure works reliably at a range of between 2000 and 2900 PSI. The best performance is delivered at 2300 PSI at a rate of 2.3 GPM. It’s an excellent replacement for vertical pressure washer pumps.

The design of the pump is built for quick and straightforward cold starts. It doesn’t require you to release pressure first before starting the engine.

The lifespan is 150 hours running time, which outdoes that of other pumps, which last only 60-80 hours. This means that it can support your home cleaning needs for three years, working weekly.The installation process is straightforward.

The Yamatic pressure washer pump is a direct drive horizontal axial pump fits most 3/4" shaft power washer, washer pressure works reliably at a range of between 2500 to 3000 PSI. The best performance is delivered at 2800 PSI at a rate of 2.4 GPM. It’s an excellent replacement for horizontal pressure washer pumps.

The design of the pump is built for quick and straightforward cold starts. It doesn’t require you to release pressure first before starting the engine.

The lifespan is 100 hours running time, which outdoes that of other pumps, which last only 60-80 hours. This means that it can support your home cleaning needs for three years, working weekly.The installation process is straightforward.

3.Triplex Plunger Pump

These are professional pumps that allow for higher pressure and last longer than the previous two.Triplex plunger pump is named for having 3 plungers in it.

There is the crankshaft, connecting rods to drive positive action pistons to suck in water. After each stroke, the pistons push out the water almost similar to the car engine. These pistons are 90% efficient and run cooler at less RPM. Triplex plunger pump is built with heavier components and bearing than axial cam pump.This kind of pump works longer than any other pump, but you may need to maintain it. They’re used in machines with a PSI higher than 3000 PSI.

We recommend for you:

This Triplex Plunger Replacement Power Washer Pump, MAX 3300 PSI / 3.0 GPM, top performance at 2500-3300 PSI and fit most 160 ~ 212 cc. based on OEM, direct-drive triplex plunger pump with adjustable unloader fits most 3/4" shaft power washer horizontal engine at 5.5 ~ 7hp (160 ~ 212cc).

The service life of the Triplex Plunger Pump is Max 500 hrs, it's more than 400% of the normal pressure washer pump. The Triplex Plunger design makes the pump run more stable, with less vibration, and provides continuous power output for your cleaning work. The fully anodized treatment for rust prevention improved the wear resistance and hardness of the pressure washer pump.Can be installed in 10 minutes.

Now you got the best guide to purchasing pressure washer pump, happy shopping for the best pressure washer pump.

    I have a pressure washer that’s made by power stroke it’s a 1900psi 1.2 gpm electric pressure washer. I need a replacement pump for it what’s the best one for me to get? Thank you John biggs

    I have a G2500PH vertical pressure washer that needs a replacement pump. The current pump is a Karcher pump 9.120-020-0. Is there a replacement pump that will fit directly on this machine and increase the pressure?
