Product description
The magnetic drive centrifugal pump of the NMQ series (abbreviated as NMQ magnetic pump) is a new type of completely leak-free and corrosion-resistant pump developed by our company according to the current needs of users and the market, combining existing magnetic pumps in the market. It is mainly composed of an electric motor, a magnetic coupler, and a corrosion-resistant centrifugal pump, using the magnetic coupler to transmit power without leaks. The feature is that when the electric motor drives the rotation of the external magnet of the magnetic coupler, the magnetic lines pass through the space and the insulation sleeve, acting on the internal magnet, causing the pump shaft to rotate synchronously with the motor without contact, transmitting the torque. At the power input end of the pump shaft, because the liquid is sealed inside the fixed insulation sleeve and there is no dynamic seal, the inevitable phenomenon of leaks, drips, and escapes in the petrochemical industry is completely eliminated, achieving a total absence of leaks.
Product introduction:
- It complies with API685-2010 and GB/T25140-2010 standards, the dimensions of the pump interface are compatible for replacing IH, CZ type chemical pumps, etc., with good compatibility, high efficiency, and low vibration.
- It uses neodymium-iron-boron or samarium-cobalt permanent magnetic materials for the internal and external magnets, with high magnetic efficiency and great resistance to high temperatures.
- According to technical requirements, it can be designed in two types: direct connection and split type; for crystalline media, a thermal insulation device can also be added.
- The modular structure is very easy to disassemble and repair, significantly reducing the professional requirements for maintenance personnel.
- A dry running protector can be configured according to user requirements to prevent damage caused by dry running.
- Absolutely leak-free, completely solves the leakage problem of sealed pumps, also being the best product to replace shielded pumps.
- The NMQ series includes more than twenty types of magnetic pumps such as NMQ (direct connection magnetic pump), NMQR (direct connection magnetic pump with air cooling), NMQL (split type magnetic pump), NMQG (split type magnetic pump for high temperature), NMQEW (direct connection magnetic pump with double thermal insulation), NMLEW (split type magnetic pump with double thermal insulation), NMZ (self-priming direct connection magnetic pump), NMZL (self-priming split type magnetic pump), NQG (direct connection pipe magnetic pump), NQL (split type pipe magnetic pump), NQGW (pipe magnetic pump with direct connection thermal insulation sleeve), NQLW (pipe magnetic pump with split type thermal insulation sleeve), among others, which customers can reasonably select according to the conditions of the medium.
