Pump Maintenance Checklist
Pump maintenance is crucial to ensure that things run smoothly and reduce the expense for repairs or loss in revenue due to productivity issues. Pumps that are not properly maintained can cost a company expensive repairs due to unneeded stress on parts or premature wearing out of the pumps. A poorly maintained pump will have to work harder to maintain its output; thus preventative measures are necessary. Having a checklist will help avoid potential problems in the future and make sure that the pump is running at its best.
Types of Pumps
There are two types of industrial pumps: 1) a centrifugal pump, which is used to transfer fluids from one location to another and 2) a positive displacement pump, which traps a certain amount of fluid in a reservoir before forcing the fluid into another pipe.
Each day the pump should undergo a visual inspection as part of maintenance, ensuring there are no leaks, corrosion or breakage. In addition, turning off unnecessary motors will guarantee that the pump is running smoothly and optimally. Changing the speed of the pump to match the output in horsepower needed will further ensure optimal performance.
Monthly maintenance should include lubricating bearings in accordance with the manufacturer's specifications, checking and repairing seals, adjusting motor couplings for efficient transfer or output, and making sure that the pump is mounted securely onto its base.
Once a year, a maintenance tech should inspect the pump to adjust, repair or replace drive belts, bearings or any damaged parts as well as performing a vibration and temperature analysis to check the motor's condition.
Along with scheduled preventive measures, a pump's efficiency can be increased by several different methods, such as using a small booster pump to help the main pump maintain its output, downsize larger pumps if no longer needed, use several smaller pumps or change the speed of the pump.
Fluid pumps emit unique sound patterns not heard with the human ear; an ultrasound analyzer can help pinpoint any trouble within the pump and pipes. Pumps are in constant motion, and a vibration analyzer detects changes in movement patterns to make sure everything is running properly.
