Common Faults And Routine Maintenance Of High-Pressure Pumps


Your high-pressure pumps are the heart of your industrial operation, yet they are often the most overlooked piece of equipment in your system until they fail. This is partly because any pump repair or maintenance work should only be carried out by properly trained personnel, who are not always available as permanent employees.

Therefore, high-pressure pumps experience two common failures:

The first is a lack of basic maintenance such as running with low or water in the oil, no or delayed oil changes, low pressure due to damaged seat O-rings, damaged plungers, or worn packing. All of these problems can damage your pump.

This is followed by poor inlet conditions, which can lead to improper filtration, dry running or cavitation, and subsequent premature priming and plunger and valve damage.

Proper maintenance of high-pressure pumps includes not only changing the oil but also checking the quality of the discharge equipment and fluid materials. In fact, HP pump maintenance requires regular inspection and repair of the pump and other components in the system.

Here are some tips to help you keep your pump and overall system performing at peak performance:

Compile a daily checklist for the entire system. Your system manufacturer, professional installer, and service team can help you create a daily inspection checklist that includes a thorough visual inspection of all critical components of the system (i.e. pump, motor or engine, fluid system, filters, piping, etc.) Check. Each section should be subdivided to contain smaller components.

Develop a preventive maintenance plan with the help of a professional services team. It may include oil changes, valve and packing changes, belt inspections, and more.

Make sure the pump is maintained in a timely manner according to the manufacturer's instructions, which usually depend on hours of operation. For example, pump manufacturers recommend that the first oil change be performed after 50 hours of operation, followed by an oil change every 500 hours or 3 months, or even less if the equipment is operating under extreme conditions.
