Factory testing ensures that the pumping package will operate and function as designed BEFORE it ships to the jobsite. The Systecon factory testing includes a flow test that guarantees the performance of the pumping system from a flow. head AND kW standpoint. This is a ZERO tolerance test that measures flow, head and system kW to compare the actual values to those predicted in the Wire to Water report included in the contract documents. Every Systecon pumping package meets the predicted performance before it ships. This means that if the package fails the performance test at the factory, it is fixed before it is shipped.
Every Systecon pumping package is tested to full design flow. Systecon has a flow test stand that can test up to 25,000 GPM. Many times for field built systems, testing to full flow is not possible. Future buildings may not be online, which allows only a partial system flow test. So, verification of full system flow for a field built system may never happen.
The factory test also includes testing of the control sequences. The sequences of operation, such as pump staging, chiller staging, valve operation, failure modes, etc. are tested. Again, this ensures that the pumping package will operate as designed. This factory testing of the control sequences streamlines the on site commissioning process. The reduction in commissioning time is ideal for fast track projects.
Note that EVERY Systecon pumping package is subject to factory performance testing. This is a requirement for all systems regardless of size or application. All instrumentation of the Systecon test stand, such as flow meters, tachometers, watt meters, etc is NIST traceable. This ensures the reliability and quality of the testing procedures and data. |
