Basic knowledge of pump operation of Washer Pump Manufacturers
In order to be able to work or troubleshoot your pump, you must fully understand how they work. The pump is the core of the high-pressure cleaning system. The pump exerts force to generate water flow. The plunger or piston moves in the cylinder of the pump, applying this force to the water. The pump is said to generate pressure, but this is technically incorrect. The pump actually just produces a flow of water. When water flows into the inlet, the inlet check valve allows water to flow into the pump, but not backflow. Then the plunger (or piston) moves forward into the water chamber, forcing the water out of the discharge check valve. The discharge check valve allows water to flow out of the pump instead of backflow.

Most pumps are designed to handle water temperatures of 140°F.

When the water in the bypass reaches 155° F, the pump will begin to fail. Pump packing, plungers, seals, and even short bypass hoses in external bypass settings may be damaged. It is best not to leave the pump in bypass mode for more than 2-3 minutes. By simply squeezing the trigger gun, you will introduce new cold water into the system.

Water shortage is the number one problem with pump performance

To diagnose any pump problem, it is important to determine the flow rate.

Always use a graduated container to check the flow rate (method of measuring the amount of water).

Air leakage will not cause cavitation. It usually leads to insufficient performance.
