NMQ-Direct-coupled Stainless steel magnetic pump

The NMQ series magnetic drive centrifugal pump (referred to as NMQ magnetic pump) is a new type of completely leak-proof and corrosion-resistant pump developed by our company based on current user and market demands, building on existing magnetic pumps in the market. It primarily consists of a motor, magnetic coupler, and corrosion-resistant centrifugal pump, with power transmitted via the magnetic coupler, ensuring no leakage. The key feature is that when the motor drives the external magnetic steel of the magnetic drive unit to rotate, the magnetic field passes through the gap and isolation sleeve, acting on the internal magnetic steel, causing the pump shaft to rotate synchronously with the motor, transferring torque without contact. On the power input end of the pump shaft, the liquid is sealed within the stationary isolation sleeve, eliminating the need for dynamic seals, thereby preventing common leakage issues in the petrochemical industry and achieving complete leakage prevention.

Designed according to ISO2858 and HG/T2730 standards, the pump interface dimensions are compatible with replacing chemical pumps such as IH and CZ, offering good interchangeability, high efficiency, and low vibration.

The inner and outer magnets are made from neodymium iron boron or samarium cobalt permanent magnetic materials, providing high magnetic efficiency and strong high-temperature resistance.

The pump can be designed in both direct-coupling and split configurations according to technical requirements, with insulation devices available for crystallizing media.

The modular structure is easy to disassemble and maintain, significantly reducing the professional requirements for maintenance personnel.

Dry-running protection devices can be configured according to user requirements to prevent damage caused by dry running.

The pump operates with absolute leakage prevention, thoroughly solving the leakage issues common with sealed pumps, making it the best alternative to shielded pumps.

Applications:
Applicable Fields: Environmental protection, petrochemical, food, biopharmaceuticals, power generation, metallurgy, aerospace, and other industries, such as refineries, ethylene plants, natural gas processing plants, various chemical plants, pharmaceutical plants, nuclear fuel plants, nuclear power plants, etc.

Applicable Processes: Clean, flammable, explosive, volatile, toxic, precious liquids, and other media requiring leakage prevention, where contamination of the medium by seals is not allowed.

Materials: The flow components of the pump can be made from various corrosion-resistant materials based on operating conditions and user requirements, such as 304, 304L, 302, 321, 316, 316L, 904, titanium alloys, nickel-based alloys, etc. For special needs, custom designs can be made based on specific operating conditions.

Design Instruction
NMQ series stainless steel magnetic pump is a new type of high-efficiency magnetic pump improved from the standard COB metal magnetic pump. The
international leading combined pull-push magnetic circuit is adopted and the design is optimized. The magnetic torque is increased by 15% under the same
size. The isolation sleeve can be made of HC276, TA2, and other materials, which greatly reduces the loss caused by magnetic eddy currents. The excellent
hydraulic model improves the efficiency of the whole machine by 3-8 percentage points. It is supported by double-sliding bearings and runs smoothly. When
the temperature is below 100 "C, the Nd-Fe-B magnetic material with the largest magnetic energy product and the samarium-cobalt magnetic material with
high-temperature resistance of 100 C -320 C are selected. The product has high compatibility, standardization, and universality.
