What is the Performance Differences between BB4 and BB5 pumps

Flow and Head

BB4 pumps typically have a flow rate (Q) ranging from 15 to 1000 m³/h and can achieve a head (H) from 180 to 2600 m. They are designed to handle a relatively wide range of flow and head requirements, making them suitable for many general - purpose industrial applications.

BB5 pumps, in comparison, can handle even higher flow rates, with some models capable of exceeding 4400 USgpm (about 1000 m³/h), and they can reach heads beyond 12000 ft (around 3660 m). This makes BB5 pumps ideal for applications that demand extremely high - volume and high - head pumping, such as in large - scale oil and gas pipelines or high - pressure boiler feed systems.

Temperature and Pressure Resistance

BB4 pumps are generally suitable for temperatures ranging from - 80 °C to + 220 °C. They are designed to operate under normal to moderately high - temperature conditions in industrial processes.

BB5 pumps can handle much higher temperatures, up to 840 °F (450 °C), and have a standard design working pressure of 2250 psig (15000 kpag). Their robust double - casing construction enables them to endure these harsh temperature and pressure conditions, which are often found in applications like carbon capture, utilization, and storage (CCUS) and high - temperature hydrocarbon processing.
