A pump oil change should be done every 3 to 5 months to keep equipment running smoothly, safely and efficiently.
Pressure Washer Pumps and Maintenance
The high pressure pump inside a hard working pressure washer is literally the heart of the machine. Leaving water in the pump can result in mineral buildup and corrosion, which wear out the pump seals and pistons.
Most pressure washer pumps use a 30w non-detergent oil. This is because most pressure washer pumps use splash lubrication.
Upgrading Pressure Washer Components
You can replace the pump in your pressure washer with a larger pump without damaging it. However, if you want it to perform at the same PSI it did before, you will also need to replace the motor with a stronger one. The maximum PSI that a pressure washer is able to put out is a combination of the Horse Power (HP) of the motor and the GPM of the pump.
Determine whether your pressure washer uses an axial or triplex pump. Your new pump must be compatible with your pressure washer.
The maximum PSI for car wash you should use is 1900 PSI. The best PSI for car wash that can effectively and safely clean a car is around 1200 to 1900 PSI.
If you’re having issues with your pressure washer, it’s possible that the problem is with the pump.
Pressure washers are made for the highest level of pressure, typically ranging from 1,300 – 2,400 psi. Some pressure washers even require a hose that can hold up to 4,000 psi.
In general, a good, properly used pressure washer pump should last for 5 to 10 years.
There are three main types of pressure washer pumps: wobble, axial cam, and triplex pumps.
