Pumps that are designed and approved for fire suppression systems can be grouped into four major categories based on configuration.

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.

Horizontal Split Case Fire Pump

These pumps use a between-the-bearings design, which means that the impeller is supported by bearings on both sides. This design provides more support for the impeller and enables it to rotate more efficiently under stress. HSC pumps place the suction and discharge nozzles (flanges) in the bottom half of the casing, on opposite sides. The impeller shaft is positioned slightly above the flanges. This sturdy but simple design is particularly suitable for higher flow applications, because it reduces thrust loads on the pump shaft and allows for operation over a broad range of flows.

A Review of Pump Types for HVAC Systems

Pumps can be grouped according to the method of displacement, the direction of fluid flow, orientation, and control capabilities. Major types of pumps include positive-displacement pumps, centrifugal pumps, and axial flow pumps.

Meets NFPA-20 (2019 Edition), Section 4.8 Standards

Toronto, June 18, 2019 – Armstrong Fluid Technology has unveiled its industry-leading, self-regulating variable speed fire pump which, in addition to new safety benefits, also holds the distinction of being the first fire pump to meet NFPA-20 (2019 Edition), Section 4.8 standards. 

“The new Design Envelope Fire Pump will provide safe, reliable performance in fire suppression systems, along with complete transparency into the operation of the pump. The Design Envelope Fire Pump also makes fire suppression systems that require a variable speed approach more affordable for contractors and building owners, as it enables a more cost-effective design for the fire sprinkler system.” said Steven Baird, Marketing Manager – Fire Products at Armstrong.
