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.

Where do Circuit Balancing Valves (CBVs) fit in a hydronic system?

 CBVs should be included in every branch of a hydronic system. For many applications such as boilers, chillers and heat pumps, they are needed to ensure balanced or equalized flow of water to all parts of a building and, as required by heating or cooling loads, across all branches of a system.

This condo tower (324 units on 13 floors) had completed a previous retrofit that unfortunately left the variable speed pumps operating in a fixed mode at low speed, so the HVAC system couldn’t cool the west-facing units in the summer.
