NB/NBF are non-self-priming vertical multistage centrifugal pumps designed for vertical motor installation. The motor shaft is directly coupled to the pump shaft via a coupling on the bracket. Tie rod bolts secure the pressure cylinder and flow-through components between the bracket and the pump casing. The pump inlet is aligned with the bottom of the pump.

The NHL/NHLF(T)/NHM series are light-duty horizontal multistage centrifugal pumps. The pump features a design where an extended shaft motor is directly connected to the rotor components, effectively reducing the installation size and creating a more compact structure. The pump is designed with an axial horizontal inlet and a vertically upward radial outlet, both of which have threaded connections. The pump is characterized by high energy efficiency, low noise, lightweight, and ease of installation and maintenance.

NBK/NBKF are non-self-priming vertical multistage centrifugal pumps. The pump uses a vertical motor, with pump components connected via a coupling. The pump's length can be adjusted by adding a empty guide vane, allowing it to meet the installation depth requirements in specific environments. The lengths corresponding to different numbers of stages can be found in the dimension and weight table or the available product range table.

The ND pump is a single-stage, inline centrifugal pump with same inlet and outlet diameters, horizontal suction, and horizontal discharge, mainly used for liquid transportation and boosting. The product is designed with an advanced hydraulic model , combined with a fully enclosed standard IEC motor, enables efficient and energy-saving operation of the pump.

The NZS pump is made using advanced processes such as stamping, expanding, and welding with stainless steel plates. It features axial water inlet and radial water outlet, with the casing fixed to the base. It equipped with a standard fully enclosed, air-cooled IEC motor. The structure is compact, the appearance is attractive, and it is efficient and energy-saving.

The NY(B)/NYL(B) pump is a air-liquid mixed pump, with a horizontal suction inlet and a vertical discharge outlet. It can simultaneously suction water and air, with mixing and pressurization inside the pump. It has high air-liquid mixing efficiency and good air-liquid dissolution. The pump has a simple structure, is durable, has a wide range of applications, operates smoothly, and produces low noise.

NIS/NISF/NISO pumps are single-stage, single-suction, non-self-priming end-suction centrifugal pumps designed based on the GB/T 5662 (ISO 2858) standard, with axial suction and radial discharge. The pump's core hydraulic components, the impeller and casing, are optimized through advanced simulation and design, offering excellent performance and smooth operation. The entire series comes standard with fully enclosed, high-efficiency IEC motors, making them more environmentally friendly and energy-efficient.

NBF and NBH are pump sets assembled by vertical multistage pumps and high-pressure pumps in serial, capable of generating a pressure of 48 bar. Each pump set consists of two pumps, both of which are non-self-priming vertical multistage centrifugal pumps. The motor shaft is coupled to the pump shaft via a coupling mounted on a bracket, and tie rod bolts secure the pressure-resistant cylinder and flow parts between the bracket and the water chamber. The pump inlet is aligned with the bottom of the pump. NBF is a stainless steel vertical multistage centrifugal pump; NBH is a high-pressure pump with an internal reverse-core structure, which reduces the pressure requirements on external components and seals. The pump sets feature high efficiency and energy saving, high lift, simple structure, and high reliability. Both use modular mechanical seals with a detachable structure, making maintenance and repair convenient and quick.

NLT(S)/LLT(S) pumps for cooling towers are non-self-priming, single-stage centrifugal pumps with identical inlet and outlet diameters. NLT(S) is horizontally installed with axial suction and radial discharge, while LLT(S) is vertically installed with horizontal suction and horizontal discharge. The pump's core hydraulic components, the casing and impeller, use a high-efficiency hydraulic model, offering excellent performance and smooth operation. They are equipped with standard fully enclosed IEC high-efficiency motors, making them more environmentally friendly and low-carbon.
