The business of pressure washers relies greatly on the equipment they use. Pump repair is a critical process that needs special attention. The process is relatively easy given enough knowledge of the person doing it. If you want to lessen the necessary repair, then maintenance is the key. The two common types of industrial grade pumps are General and Cat. General is the most popular in terms of sale while Cat leads in terms of suction power for it is said that it can suck better in plastic containers.
The pump is directly connected to the main engine while two parallel belts are connected to the pump to power it. In order for the pump to do its job, it needs the right amount of water flowing in it. Insufficient water can lead to burn out. Turn off the engine as soon as you see that there is no more water running in the pump. Also, you have to change the oil in a span of once a month.
During pump repair, you have to check the valves inside the pump. It is ideal to change the pumps after 300-500 hours of use. Changing the valve is easy. You just have to remove the bolt, remove the valve and then replace it with the new one. Put back the old bolt and wrench it tightly.
Once you drain the oil, you will know if you have a problem with either the water or the oil itself. If the oil has bubbles or if it turned white, then it means it overheated due to lack of water or the casing might have cracked.
The belts should be checked as well. Keep it nice and tight. Look out for drips. If there is a drip, use the ever reliable Teflon tape. Not only will this stop the leak, it also prevents rust formation and it is also convenient to separate if you ever need to refit in the future.
Low pressure inside the pump is one of the most common pump repair problems. There are a multitude of reasons that may cause this. Among these reasons include faulty water supply, leakage in the hose, belt slippage, worn out gun nozzle tip, slow engine rpm, faulty pressure gauge, malfunctioning spray nozzle tip and dirty inline filter.
Since your machine is the one that brings in the money, you have to make it your business as well as to check it regularly for little damages and future repairs. Sometimes, all you have to do is listen to the pumps. If it is making too much noise then it may be time to check the air suction line, bearings and the valves.
Pressure washing contractors should have more than the basic knowledge concerning the repair and maintenance of their machines. Just think, this is only the pumps that are being discussed here. If you do not know how to handle pump repairs, better ask the assistance of the professional to avoid further damage.
