Water cavitation on a pressure washer

 Water cavitation on a pressure washer is the process of gas bubbles forming and collapsing inside the pump, which can damage the pump and cause premature failure. 

Cavitation occurs when the pump's inlet doesn't supply enough fluid to match the amount being discharged from the outlet. This can happen when the net positive suction head (NPSHR) needed by the pump isn't available. The NPSHA is the minimum pressure required at the suction port to prevent the liquid from boiling or evaporating. 

To prevent cavitation, you can: 

• Ensure the pressure applied at the suction port is greater than the liquid's vapor pressure 
• Match the pump specifications to the fluid and system requirements

the pump has been over-pressurized

 

-What you show as leaking means the pump has been over-pressurized and is probably not repairable. -

-Over-pressurized means the adjustable knob on the top was turned clockwise beyond the pump's capacity.

-Specifically which model number do you have, or horsepower of the motor or label on the top of the pump.

system of seals and valves

 

A pressure washer relies on a system of seals and valves to control and direct the flow of water from the inlet to the pump, then to the outlet and the cleaning nozzle. When the water seals are in good condition, they provide a strong barrier that prevents water from leaking into the oil chamber of the pump.

However, as the water seals wear out – due to general wear and tear, aging, corrosion, or improper maintenance – they can start creating small gaps or cracks. When this happens, water can start to seep through these gaps and mix with the oil in the oil chamber. This can lead to water contamination in the oil, which can further degrade the pump's performance.

Pump oil must remain pure and free from contaminants to lubricate the moving parts effectively. Once water enters the oil chamber, it reduces the oil's lubricating properties, leading to increased friction, overheating, and potentially, serious damage to the pump mechanism. Hence, it's advised to regularly inspect and replace the water seals when necessary to ensure the pressure washer's optimal performance.

Replacement water filter

 A pressure washer water filter is a device that is used to remove impurities from the water that is used in a pressure washer. These impurities can include dirt, sediment, and other particles that can damage the pressure washer over time or affect the quality of the cleaning.

The filter typically attaches to the water inlet of the pressure washer and uses a fine mesh stainless steel to trap the impurities before they enter the machine.

Comet pumps

 

Comet pressure washer pumps are known for their durability because they are made with high-quality materials and are designed to withstand the high-pressure and high-temperature conditions of pressure washing applications. Bronze connecting rods ensure long life and are considered the most significant upgrade for direct drive pressure washer pumps. 

The pumps are made with aluminum alloy and stainless steel, which are both corrosion-resistant and able to withstand high pressure

 Additionally, they are designed with thermal relief valves and low pressure seals, which help to protect the pump from overheating and high-pressure damage.

Finally, Comet pumps are tested thoroughly before leaving the factory to ensure its reliability.
