Factory Pump Testing Services: Why is this Important?

Blog | June 12th, 2020

A wide range of industries is utilising the benefits and capabilities of pumps on their operations. The automotive industry use pumps for water-cooling and fuel injection purposes. Alternatively, the energy industry use pumps to pump oil and natural gas. The said industry also utilises pumps to operate cooling towers and components of the heating, ventilation, and air conditioning systems. As for the medical industry, it maximises pumps for the development of medicine and artificial body parts replacements.

The overall design and functionality of pumps make them suitable for a lot of applications. Pumps are devices that move and lift liquids from their source through mechanical action. This movement allows the conversion from one type of energy into hydraulic energy. These devices can work with energy sources like electricity, wind, diesel, and others. The basic types of pumps are positive displacement, centrifugal, and axial-flow pumps.

Testing Pumps is Essential

Given the importance of pumps in various industries, pump manufacturers would typically place these devices under different types of factory tests to ensure that they meet the standard requirements by certain industries. These manufacturers ensure that their pumps can certainly function and perform well under different conditions and situations with a huge consideration of extreme variables. The stricter nature of factory tests contributes to the release of highly capable pumps in the market.

Most factory pump testing procedures are done in private. All results that will be produced by the tests are brought in and checked by the engineering department of a pump manufacturer, which has the last say whether a pump passed the tests or not. In some cases, however, companies or clients who are interested in buying pumps can witness the testing procedures of the said devices. This kind of practice ensures that prospective buyers are guaranteed high-quality and dependable pumps, especially if they are familiar with all the elements surrounding these devices.

Types of Factory Pump Tests

Manufacturers would conduct different types of tests to ensure the release of high-quality and dependable pumps in the market. One of these tests is the hydrostatic pressure test. This type of test is done to verify and confirm the integrity of the pump casing. Manufacturers apply maximum operating pressure to determine if there are any presence of leaks and strength issues.

A mechanical test, on the other hand, is conducted to know if the vibration levels, bearing temperatures, and noises levels of the pump are within its recommended levels and capacity. If a pump exhibits appropriate levels of vibration and noises and reasonable bearing temperature, then it successfully passes the said test. 

The head and flow produced by the pump are both measured in a performance test. These variables, alongside the input power to the pump, are all evaluated at numerous operating points to effectively assess the efficiency and effectiveness of the device. Another test that is conducted by manufacturers is the net positive suction head (NPSH) test. This type of test is done by reducing the suction pressure to a pump. A pump will only pass this test if its result is analogous to the NSPH values that are present on previously approved pumps. Conducting all these tests in the factory enables manufacturers to easily modify the pump especially if it can still be fixed. All the necessary materials are already present to do significant adjustments and changes. This benefit makes factory pump testing services crucial for numerous industries.
