Standard Centrifugal Pumps: NT / NB Series
Whether it’s complex cooling and heating systems, industrial processes, or municipal water supply—large-scale projects demand uncompromising operational reliability. Biral standard centrifugal pumps (NT series) and monoblock pumps (NB series) offer robust designs, flexibility, and excellent efficiency.
NT Series – The Classic Standard Centrifugal Pump
NT 1450 rpm and NT 2900 rpm
Primary pump for large heating, ventilation, and cooling systems, district heating, or a wide variety of industrial and water supply processes. The standard centrifugal pump, mounted on a base plate, features an axial suction port and a radial discharge port. The pump and motor are connected by a flexible coupling, which simplifies maintenance. Thanks to the modular design, the pump can be precisely customized for the desired application. Depending on requirements, the pump is available with a standard mechanical seal for water up to 110 °C, a mechanical seal for water/glycol mixtures from 0 to 100 °C, or a mechanical seal for hot water up to 140 °C.
NB Series – The Compact Block Pump
NB 1450 1/min & NB 2900 1/min
Primary pump for large heating, ventilation, and cooling systems, district heating, or a wide variety of industrial and water supply processes. This single-stage volute casing pump features an axial suction port and a radial discharge port. Thanks to its monoblock design, the pump is particularly compact. The drive unit and impeller can be installed and removed without disassembling the pump housing. Depending on requirements, the pump is available with a standard mechanical seal for water up to 110 °C, a mechanical seal for water/glycol mixtures from 0 to 100 °C, or a mechanical seal for hot water up to 140 °C.
