In commercial plumbing installations, which often incorporate large diameter pipework and pumped systems, water hammer can be a single destructive event that occurs when a pressure wave rapidly propagates through the pipework. The magnitude of the incident and the reflected pressure waves can sometimes exceed the rated operating pressures of components within the plumbing system. Surges can typically exceed 1.5 times the normal system operating pressure.

In 2018, the HVAC system at a popular holiday resort suffered a series of failures and leaks, resulting in frequent downtime. An initial review determined that the existing pumps were the cause and had to be replaced. The review also noted that the pumps were oversized, which affected system efficiency. With the resort occupancy rates near 95% for most of the year, HVAC performance and reliability are crucial, so managers decided to go ahead with an upgrade.

Design Envelope Fire pumps are designed, assembled, and tested to meet the code requirements of a Self-Regulating Variable Speed Fire Pump Unit, as described in NFPA 20 – 2019 edition. Design Envelope Fire pumps are factory-built, integrated fire pumps consisting of a Vertical In-Line pump, driver, and variable speed control unit. They’re configured to maintain a set pressure until the maximum power draw is reached, while modulating pump speed to control to meet limits on pressure or suction.

A domestic water pressure booster system is essential for buildings with inadequate supply pressure from the city or buildings served from storage tanks. A booster ensures potable water is available at appropriate pressures on every level of a building. Because flow demand in most buildings is highly variable, variable frequency drives and automatic controls are an excellent option to reduce the energy used to maintain constant pressure.
