CAT Pressure Washer Pumps

The strongest most durable power washers on the market often have CAT pressure washer pumps on the inside.

Those machines used in commercial and industrial applications such as factories, farms, commercial buildings and warehouses, and for cleaning heavy duty equipment are expected to absorb a higher amount of wear and tear. Just like any other pressure washer, the pump is at the heart of the machine and can often require replacement depending on use.

Among the highest rated parts you can buy, especially for heavy duty applications, are Cat Pumps. The company manufactures pressure washer pump parts across a wide spectrum of machines including those powered by gasoline, diesel fuel, or electric. This also includes portable, stationary or trailer mounted machines, both hot or cold.

Aside from making sure that there is adequate pressure washer pump oil in the reservoir there are other factors in maintenance. If you are replacing a worn or broken part always be sure to select the right pump and install it properly. Consult the pressure washer manufacturer's information about replacement parts. Chances are they will be able to assist in choosing the right CAT pressure washer pump. Using a part on a machine for which it was not designed will cause problems down the line. It is especially important to adhere to specifications such as pump rating, flow and pressure rating, and whether the pump is designed for hot and cold water or just cold.

Ongoing Pump Maintenance

First and foremost, the pressure limit specification needs to be adhered to and that is accomplished by monitoring the pressure gauge. It will monitor system pressure and provides information about potentially dangerous changes. Being able to set the pressure is a great way to protect your investment. A regulator or unloader is used to set system pressure. The regulator is basically a valve that will go into by-pass mode if something blocks or interferes with the flow in the discharge line which can really damage the pump mechanism. With industrial or commercial grade machines there may be a secondary relief valve that can be set slightly higher than the primary protection. It is crucial that these devices exceed the flow and pressure rating of the pump itself. The product manual or specifications will most likely include the proper specifications.

Hot water power washers require even more protection. These systems should also have a monitored and pressurized inlet. A thermal relief valve to release high temperature liquid from the by-pass line is recommended. Another precaution would be a temperature control that shuts the system down at pre-set temperature levels.

The most effective way to protect mechanical devices over the long term is regularly scheduled maintenance. Most manufacturers have specific guidelines for service intervals and a preventative maintenance checklist. Changing the oil regularly is not too difficult and should be done using the manufacturer's recommended oil. Regularly inspect the seals and gaskets for leaks or excess wear and tear.
