Pump testing evaluates pump efficiency, safety, and functionality. Fluid pressure and flow are commonly evaluated, and tests can be done on individual pumps or entire stations. Flowmeters are used for testing, and guidelines ensure consistent results. Thermodynamic tests focus on energy use and temperature changes.
Pump testing is a method by which a wide variety of pumps are evaluated for efficiency, safety and overall functionality. The process is commonly completed annually as part of regular maintenance. Pumps can also be tested before being purchased to ensure they can handle the expected flow. Tests can be performed on equipment such as fuel, sump or water pumps.
Two of the most common specific items evaluated during pump testing are fluid pressure and flow. By measuring these things, you can determine if a pipe has adequate capacity for the level of fluid it processes. These items can also show whether energy is being used efficiently.
The pump test can be performed one pump at a time or with an entire pump station. While testing individual pumps can help resolve specific problems, testing all pumps simultaneously can help a professional evaluate whether the system as a whole is performing adequately. The pump testing process typically includes both types of testing as there are strong benefits to both big picture analysis and tuning. It is also possible that one pump on its own works differently than other pumps. One that might be acceptable on its own might not work when done with the rest of the system.
The flowmeter is the primary tool used in most pump tests. It is connected to the pump, where it then records the amount of energy used. The gauge also evaluates the difference between the external and internal fluid pressure. Tests usually consist of a series of small tests performed at timed intervals.
Pump testing can be done in-house or outsourced. If it’s done by employees, often the best results come from the people who work with the pump system on a regular basis. There are also testing facilities where equipment can be brought in for examination.
Most organizations will have guidelines for performing a pump test. These may include instructions for the test process or a list of standards the equipment must meet. There may also be scoring systems that can be used to measure the adequacy of the pump. By having guidelines for these tests, an organization is more likely to have consistent results, which can ease the process of potential troubleshooting and remediation.
In addition to general pump tests, there are also thermodynamic pump tests. These focus only on the amount of energy used and changes in temperature. They are most often performed to ensure efficient use of energy and safety.
