It is always a good practice to consider the entire system when purchasing pumps. Focusing on just the pump without considering the control method and instrumentation, for instance, is shortsighted and will result in suboptimal operation. However, the design and packaging can be done individually and input into a building management system or as a package from the pump manufacturer that fits into the building management system.

An example of pumps that are supplied as packages with driver and controls are fire pumps. These pumps are governed by code (state, local, national building code and international building coded, with National Fire Protection Agency standard, NFPA-20 acting as the guiding standard). Fire pumps will have third-party certification and listings that verify the pumps are constructed to the guiding standard. The underwriting listing agency verifies the fire pump package, with the pump manufacturer being responsible for use of approved components (see Image 1).
